Product Overview:
The WJ18 product collects humidity and temperature signals and reports them to various MQTT servers suchasAlibaba Cloud, Tencent Cloud, Huawei Cloud, China Mobile IoT OneNET, Private Cloud, etc. through WiFi. It alsosupports accessing data through Modbus TCP protocol, and real-time temperature and humidity data can be viewedthrough the module's built-in webpage. The WJ18 product can also enter low-power mode for battery poweredapplications. The WJ18 product can be applied to smart factory MES system, temperature and humidity collection inagriculturalgreenhouses, temperature and humidity monitoring in smart warehouses, data reporting from small weather stations, real-time monitoring of hospital environments, comfort testing of high-end residences, and more. The product includes a high-precision temperature and humidity sensor and a high-performance WiFi module.The communication method adopts MQTT, character protocol or MODBUS TCP protocol. TCP is a transport layerbased protocol that is widely used and a reliable connection oriented protocol. Users can directly set moduleIPaddresses, subnet masks, etc. on the webpage, and all user set parameter settings and configuration informationarestored in non-volatile memory EEPROM. The WJ18 series products are designed and manufactured according to industrial standards, with stronganti-interference ability and high reliability. The working temperature range is -40 ℃to+85 ℃.
