KL103 & KL103L Air Quality Monitoring Sensor

KL103 is a compact indoor ambience monitoring sensor for measurement of temperature, humidity and CO₂. These data will be shown on the E-ink screen in real-time, which allow to quantify the indoor environment and comfort. KL103 is widely used for office, store, classroom, hospital, etc.

Apart from screen display, sensor data can also be transmitted using LoRaWAN. With this low-power technology, KL103 can work for more than 3 years with 2 replaceable batteries. Combining with KLED LoRaWAN gateway and KLED IoT Cloud solution, users can manage all sensor data remotely and visually.
