AM104/AM107 is a compact indoor ambience monitoring sensor for measurement of temperature, humidity, light, CO2 concentration, TVOC, barometric pressure and motion. These data will be shown on the E-ink screen in real-time, which allow to quantify the indoor environment and comfort. AM104/AM107 is widely used for offices, stores, classrooms, hospitals, etc. Apart from screen display, sensor data is also transmitted using LoRaWAN ® technology. With this low power consumption technology, AM104/AM107 can work for one year with 2 replaceable AA batteries. Combining with Milesight LoRaWAN ® gateway and Milesight IoT Cloud solution, users can manage all sensor data remotely and visually.
