The Dragino LAQ4 is a LoRaWAN Indoor Air Quality Sensor for Internet of Things solutions and is designed to measure surrounding environment parameters, including TVOC (Total Volatile Organic Compound), eCO2 (equivalent CO2), temperature, and relative air humidity, uploading the data to an IoT server via LoRaWAN wireless protocol.
IAQ (Indoor Air Quality) is a very important factor for indoor activity and human life. VOC (Volatile Organic Compound) gas emissions from certain solids and liquids are the main source for poor indoor air quality. LAQ4 helps you monitor IAQ and, like other TVOC sensors, LAQ4 can be calibrated for more accurate measurements of TVOC and eCO2.
