The FC-706-HX module is used as a low-power integrated reading system, which not only solves the problem of the meter itself (usually for water, gas, heat meters, etc.) that is difficult to obtain electricity, but also realizes the real time information interaction between the master station and the meter, the network uses a series of measures to control the power consumption of each node, which is a good choice for a collection system that not only needs to use battery power, but also to ensure remote data transmission.
