LoRaWAN uses unlicensed spectrum and your own gateways, suiting wide sites such as farms or industrial estates. Where power and network already exist, LAN or Wi-Fi is often simplest. Test on site before choosing." - question: "Can old machines use IoT?" answer: "Usually, yes. Start by reading data from the PLCs or control panels you already have; where a machine cannot share data, add an external sensor such as a power meter or vibration sensor instead of replacing it. A site survey confirms this before work starts." - question: "Is IoT secure, and what should I watch for?" answer: "It can be, if designed in from the start. Following NISTIR 8259A, choose devices that can be identified, have changeable default passwords, encrypt data, close unused ports and receive updates. Put IoT on its own network, give every user a role-based login, and handle camera footage under Thailand's PDPA." - question: "How much does an IoT system cost?" answer: "Costs split into devices, installation, connectivity, cloud and software, each paid to a different party; hardware prices depend on models and point count. At iReadCustomer, software is priced from ฿7,990 per man-day and custom projects start at ฿50,000. Start with a pilot: one problem, one area." robots: "noindex, follow" --- # What Is IoT? An Internet of Things Guide for Thai Businesses What IoT stands for and how it works, in business terms: sensors, gateways, MQTT, LoRaWAN and NB-IoT, examples from Thai factories, cold chains, energy, buildings and fleets, plus AI, security basics, cost and how to start with a pilot. **What is IoT?** **IoT, the Internet of Things, means letting the physical things in a business, such as machines, sensors, cameras, power meters and trucks, send data over a network on their own, with nobody writing readings down.** Software then shows that data on a dashboard, alerts the right person or triggers the next action. For an owner, IoT means knowing what is happening on the floor now, not after the damage is done. Below: how it works, the parts, Thai business examples, AI, security and cost. Have a problem to solve already? See our [IoT and robotics development](/en/services/iot-development) page. ## What IoT stands for, and what it really means IoT stands for **Internet of Things**. The "things" are anything that can be measured or controlled: motors, freezers, pumps, doors, trucks. Recommendation ITU-T Y.2060 (2012) from the International Telecommunication Union defines it as a global infrastructure for the information society, enabling advanced services by interconnecting physical and virtual things through interoperable information and communication technologies. In business terms, the value is not that a device is online. It is that **data from the floor reaches the person who has to decide, in time**. A cold room that drifts out of range at 2 a.m. costs far less if the shift lead hears about it at 2 a.m. rather than at the morning check. Industrial IoT (IIoT) is the same idea in factories: joining PLCs, sensors and control panels to dashboards, reports and ERP, with tougher hardware and stricter security. ## How IoT works: four steps from floor to decision Every IoT system, small or large, follows four steps: 1. **Device.** A sensor, camera or machine measures something: temperature, vibration, current, running or stopped. 2. **Connectivity.** The reading travels over a network such as plant LAN, Wi-Fi, 4G, NB-IoT or LoRaWAN, usually through a gateway that collects data from many points. 3. **Platform.** Software stores the data, keeps its history, shows it on a dashboard and checks it against rules. 4. **Action.** A LINE or email alert goes out, a report is produced, data flows into the ERP, or a command goes back to a machine. In a cold room: the sensor reads, the gateway forwards, the dashboard checks the limit, and the shift lead's LINE group hears the moment it is crossed. ITU-T Y.2060's reference model has four matching layers (device, network, service and application support, application), with security spanning all four: it is designed in, not added later. ## The parts of an IoT system **Sensors and devices.** Temperature and humidity for cold rooms and warehouses, vibration for motors, power meters per machine or zone, level sensors for fuel and water tanks, door switches, GPS for vehicles, IP cameras for inspection and safety. Before buying sensors, check what your machines already know: **a lot of data already sits in your PLCs and control panels**. **Gateways and edge.** A gateway collects data from many devices, translates protocols and sends it on, buffering readings when the internet drops. For AI cameras, an edge box runs the model on site, so video stays inside the plant. **Networks.** Choose by area, data volume and power source: | Network | Good for | Know this | |---|---|---| | LAN or Wi-Fi | Sites with power and network; cameras | Keep IoT on a separate network from office PCs | | 4G / 5G | Vehicles, places you can't cable | Monthly SIM fee per device | | NB-IoT | Low-data, battery-powered meters, including indoors | 3GPP standard on mobile operators' networks | | LoRaWAN | Farms, industrial estates, multi-building plants | Unlicensed spectrum; you can run your own gateways | NB-IoT is a narrowband radio technology for IoT that 3GPP, the body behind mobile standards, finished standardising in June 2016 as part of Release 13. LoRaWAN is the LoRa Alliance's low-power, wide-area (LPWA) specification in unlicensed bands; the Alliance cites up to 15 km of range in rural areas and 10+ years of battery life. Test on site first; obstacles and reporting frequency change real results. In Thailand, the NBTC's rules for IoT in the 920–925 MHz band, including device technical standards, took effect in 2017 (B.E. 2560); check that wireless devices meet the current rules. **Protocols.** MQTT is a lightweight, open OASIS standard (version 5.0 approved on 7 March 2019) for moving device data to a platform. Devices publish readings under a topic; systems that need them subscribe. It is built for constrained devices and limited bandwidth, with three quality-of-service levels. A gateway can translate factory protocols such as Modbus. Open standards let you change vendors later. **Platform.** Time-series storage, dashboards, alert rules, Excel and PDF exports, and data sent into your ERP: output, machine hours, energy. If IoT data never reaches the systems your team already uses, it becomes one more screen nobody opens. ## IoT examples for Thai businesses Start with the problem that costs you most when you find out late. **Factory machine monitoring.** Live status (running, stopped, waiting, and why) shows where production time goes and feeds OEE, which combines availability, speed and quality. Vibration and temperature sensors on motors let maintenance plan repairs before a breakdown, and cameras count and measure parts. For AI in quality, maintenance and scheduling, read our [AI manufacturing operations guide](/en/blog/the-ai-manufacturing-operations-implementation-guide-quality-maintenance-and-scheduling). **Cold chain.** Sensors in cold rooms, freezers and refrigerated trucks alert when a limit is crossed or a door is left open. The automatic temperature history doubles as evidence for customers and for GMP or HACCP audits. **Energy.** Meters per machine or zone show where power goes and what is left running after a shift; against output, they give energy per unit. **Smart buildings.** Leak and pump sensors alert maintenance before a plant room floods; gate cameras log licence plates; cameras flag entry into restricted zones. **Fleet tracking.** A fuel-level sensor paired with GPS shows where and when fuel dropped abnormally, reefer units report temperature during the trip, and a dock scale compares real weight with the order to catch short-loading.

Models must be trained and tested on images from your own floor. **Anomaly alerts** learn each machine's normal pattern and warn when vibration, heat or power use starts to drift, before a fixed limit is crossed. They need history, so **start with simple thresholds your team understands** and add AI once enough data exists. AI can be wrong, so keep a person in the loop for important calls and tune alerts until they reach the right person without crying wolf. ## Security basics Every IoT device is a door into your network. NIST's NISTIR 8259A (May 2020) sets six baseline capabilities an IoT device should have, which make a good buying checklist: | Capability | Ask the vendor | |---|---| | Device identification | Can each device be uniquely identified? | | Device configuration | Can default passwords and settings be changed only by authorised people? | | Data protection | Is data encrypted when stored and sent? | | Logical access to interfaces | Can unused ports and services be closed? | | Software update | Are security updates provided, and how are they applied? | | Cybersecurity state awareness | Does the device log or report suspicious access? | On the system side: a separate IoT network, role-based logins with an audit log, cloud accounts in your company's name, and camera footage handled as personal data under Thailand's PDPA (why it is kept, for how long, who can see it). ## Cost, and how to start with a pilot There is no single price for "an IoT system". You pay devices to the hardware seller, installation to your integrator, SIM plans or gateways to the network provider, cloud hosting in your name, and software to a development team. Hardware and connectivity prices depend on models, point count and site, so get quotes after a survey. At iReadCustomer, software is priced by the man-days the scope needs, **from ฿7,990 per man-day**, and custom projects start at ฿50,000. You see the number before work starts; see [how pricing works](/en/pricing). A pilot keeps the risk small: 1. **Pick one problem** that hurts most when found late. 2. **Survey the site** to see what your machines, cameras and network can already share. 3. **Run it for real in one area** and tune the alerts. 4. **Measure against targets agreed in advance**, such as how much sooner you learn of an incident. 5. **Grow once it works**, extending what was built rather than starting over. ## Starting with iReadCustomer iReadCustomer builds the software layer of IoT: connecting sensors, cameras, machines, PLCs and robots, with dashboards, LINE alerts, AI vision, reports and ERP integration. We don't make hardware, change PLC control logic or program robot motion; we work with the equipment you have and alongside your integrator.
