LoRaWAN™ modem GM-2 is designed to take readings from Elster gas meters, with the subsequent accumulation and transfer of this information to the LoRaWAN™ network.
The modem is equipped with Hall sensors, one of which calculates the current meter readings and the other is located in such a way and has a sensitivity level that reacts only to the presence of an external magnetic field (for example, when a strong magnet is placed near the gas meter to disable the counting mechanism).
To protect against unauthorized access, the modem has a tamper. There are also two security inputs and two open-drain outputs for control of an external devices.
The modem is powered by a 3400 mAh soldered battery with up to 10 years life up. The modem acts as a LoRaWAN™ device of class A.
