With LoRaWAN® module, it transmits the sensor value via gateway to networks server and application server. User can monitor the status remotely. It is optional for different frequency, such as 470Mhz (China), 868Mhz (Europe), 915Mhz(USA), 923Mhz (Australia). As it is with algorithm of low power consumption, the internal battery can work for more than 1 years for one charge (With different parameter, 3 years lifetime is realized).
1) More than 3 years battery life
2) -141dBm sensitivity
3) 3,000m emission distance in the view area
4) Through the gateway, it can upload the data into cloud
