Wireless LoRaWAN Water meter with Valve control

RHF1S052 is a LoRaWAN Smart water meter designed by RisingHF. It supports dual- input pulse counter to achieve water meter reading.

RHF1S052 Smart water meter sense meter reading real time, and uplink to LoRaWan server periodically. It also support reading the history data via the downlink command.
The sensor with local data storage offered a backup support for the meter reading in
data management which offered an alternative mean for the database server to
collect the data.

RHF1S052 is designed for Cold /hot/warm water meter which has built-in motor engine to support Valve control and work in LoRaWAN class A or B, to improve the downlink control respond time.
