AM103 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. AM103 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, AM103 can work for more than 3 years with 2 replaceable batteries. Combining with Milesight LoRaWAN® gateway and Milesight IoT Cloud solution, users can manage all sensor data remotely and visually.
