Product Overview:
The WJ18 product realizes the collection of humidity and temperature signals, which are reported to Alibaba Cloud, Tencent Cloud, Huawei Cloud, China Mobile IoT OneNET, and private through WiFi
Various MQTT servers such as the cloud also support accessing data through the Modbus TCP protocol, and can be viewed through the built-in web pages of the module
Temperature and humidity data for the hour. The WJ18 product can also enter low-power mode for battery powered applications.
The WJ18 product can be applied to the smart factory MES system, agricultural greenhouse temperature and humidity collection, smart warehouse temperature and humidity monitoring, and small meteorological station data reporting,
Real time monitoring of hospital environment, comfort testing of high-end residential buildings, and so on.
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 layer based protocol that is widely used, connection oriented, and reliable. Users can directly set up on the webpage
The module IP address, subnet mask, and other configuration information set by the user are stored in the non-volatile memory EEPROM.
The WJ18 series products are designed and manufactured according to industrial standards, with strong anti-interference ability and high reliability. Working temperature range -40 ℃ to+85 ℃.
