Product Description

4-channel DI switch detection counter, MQTT protocol, online webpage display, WiFimodule WJ162

Product Overview:
The WJ162 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchangebetween sensors and networks. The switch data of the sensor can be forwarded to the network.The WJ162 series products include power conditioning, switch quantity acquisition, and WiFi networkinterfacecommunication. The communication method adopts MQTT protocol. TCP is a transport layer based protocol thatiswidely used and a reliable connection oriented protocol. Users can directly set module IP addresses, subnet masks, etc.on the webpage. Can be used for monitoring and controlling the operation of sensor devices. The WJ162 series products are intelligent monitoring and control systems based on microcontrollers, whereusersetmodule IP addresses, subnet masks, and other configuration information are stored in non-volatile memory EEPROM. The WJ162 series products are designed and manufactured according to industrial standards, withstronganti-interference ability and high reliability. The working temperature range is -45 ℃to+85 ℃
