EM500-CO2 is designed for measuring CO2, temperature, humidity and barometric pressure in harsh environments and transmitting data using LoRaWAN® technology. With this low power consumption technology, EM500-CO2 can work up to 10 years with 19000 mAh battery. Combining with Milesight LoRaWAN® gateway and Milesight IoT Cloud solution, users can manage all sensor data remotely and visually.
EM500-CO2 is widely used for applications like smart agriculture, smart city, forest fire detection, etc.
