LoRaWAN Non-magnetic Coil Metering Module
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.

NB-IoT wireless transparent transmission module
HAC-NBi module is an industrial radio frequency wireless product independently developed by Shenzhen HAC Telecom Technology Co., LTD. The module adopts the MODULATION and demodulation design of NB-iot module, which perfectly solves the problem of decentralized ultra-long distance communication in complex environment with small data volume.
Compared with the traditional modulation technology, THE HAC-NBI module also has obvious advantages in the performance of suppressing the same frequency interference, which solves the disadvantages of the traditional design scheme that cannot take into account the distance, disturbance rejection, high power consumption and the need for a central gateway. In addition, the chip integrates an adjustable power amplifier of +23dBm, which can obtain a receiving sensitivity of -129dbm. The link budget has reached the industry-leading level. This scheme is the only choice for long-distance transmission applications with high reliability requirements.
