WS868-LW is a low-power, small-sized LoRaWAN module designed and developed by Shenzhen Youxunda Technology Co., Ltd., embedded with Semtech's LoRa chip SX1276 and ST ultra-low-power STM32 series MCU, in line with the release of LoRa Alliance. The LoRaWANTM protocol standard enables easy and fast IoT networking (with LoRaWAN gateways).
The user equipment can interact with the module through the serial communication interface (UART). The module supports AT command set, firmware upgrade, AES encryption, low power consumption, network access activation, etc., and has rich peripheral communication interfaces (UART, ADC). , SPI, PWM, GPIOs, etc.), to provide users with flexible and simple LoRaWAN network data access operations.

The FC-RF701 wireless water and gas heat meter module can work in three working modes: water meter, gas meter and heat meter. In the water meter or gas meter mode, only a 3.6V lithium sub-battery, two reed switches, and a motor can be connected externally to realize all the electronic parts of the water meter or gas meter, plus the mechanical equipment of the water meter or the gas meter. In part, it constitutes a complete water meter or gas meter with pulse acquisition function, billing function, and wireless meter reading function. In the heat meter mode, it is only necessary to externally connect a heat meter with RS485 interface, RS232 interface or TTL level interface to realize wireless remote meter reading of heat meter data. In the above three modes, the FC-RF701 module can use the handheld device developed by our company to realize long-distance wireless meter reading. Communication between the FC-RF701 and the handheld is fully compliant with the CJ/T188-2004 protocol.

Gas meter for double-reed switch water meter and double reed switch;
Suitable for photoelectric direct reading water and gas meter of RS485 interface, RS232 interface and TTL interface;
