LoRaWAN Non-magnetic Coil Metering Module

Short Description:

HAC-MLWS is a radio frequency module based on LoRa modulation technology that complies with the standard LoRaWAN protocol, and is a new generation of wireless communication products developed in combination with practical application needs. It integrates two parts in one PCB board, i.e. non-magnetic coil metering module and LoRaWAN module.

The non-magnetic coil metering module adopts HAC’s new non-magnetic solution to realize the rotation counting of pointers with partially metallized discs. It has excellent anti-interference characteristics and completely solves the problem that traditional metering sensors are easily interfered by magnets. It is widely used in smart water meters and gas meters and intelligent transformation of traditional mechanical meters. It is not disturbed by the static magnetic field generated by strong magnets and can avoid the influence of Diehl patents.
