Smart Indoor Air Quality Monitor (IAQ)

SIAQ is a Smart and Modular designed Indoor Air Quality Monitor, equipped with a touch and beautiful color LCD display for easy viewing at a distance and noticing the alerts by color changing. With ModbusRTU or ModbusTCP, it can easily integrate into the existing BMS system, PLC, SCADA system in your facility, or factory. With Wifi, Ethernet, or NB-IoT version, it can connect to Globiots platform or any IoT platform for remote monitoring and data analytics. For Sigfox and LoRaWAN versions, please contact us. The device has built-in sensors to measure temperature, humidity, CO₂, PM1.0, PM2.5, PM10, TVOC, and HCHO formaldehyde. Those advanced sensors are from Germany, Japan, and the USA to deliver the highest accuracy and stability. This professional smart IAQ monitor is used in office buildings, schools, hospitals, factories, warehouses, laboratories... or any facility.
