Landis Gas Meter Pulse Reader
The gas meter reader sensor is specifically designed to measure usage from Landis, Elster, or similar gas meters. As the rotating part of the gas meter passes through these sensors, it initiates a reading, enabling remote meter reading. This gas meter reader integrates with LoRaWAN technology to support wireless communication, leveraging STMicroelectronics' advanced LoRa technology.
