7.Introduction of FSK
The wireless remote valve controlled water meter is composed of two parts: a separate wireless meter and a separate wireless gateway.
The separate wireless meter is Low-power electronics by the SX1208 wireless chip of Semteck Company, through the main control MCU of St to achieve communication, measurement, valve control in one of the integrated control;
The split wireless gateway is responsible for collecting and transmitting data tables, and connects to the public network through the NB-IOT network. The gateway can support the Telecom, Mobile and UNICOM networks with a wide range of applications, at the same time optional gateway swipe card (T5557-RRB- function, known as meter reading in the"WiFi router.".
