major function

One way temperature, one way humidity intelligent digital temperature and humidity monitor. Using a digital display to cyclically display the measured values of current temperature and humidity can effectively prevent various accidents caused by high temperature, humidity, and condensation. Its unique high temperature alarm, low temperature alarm, load disconnection alarm, and sensor abnormal alarm output can better ensure the safe and efficient operation of unmanned power supply systems.

In addition, the product also has 3-channel load output function (2-channel heater, 1-channel fan), temperature and humidity analog output function (0-5V or 4-20mA), RS485 communication function and self checking function.
