Product Description:
WiFi temperature/humidity detection alarm, large LCD screen display; support mobile APP to arbitrarily set upper and lower limits, when it is lower than the set lower limit at that time, the device starts to send an alarm prompt, and the mobile APP receives the alarm information at the same time;
◎USB power supply, built-in 500MA battery, can be used without power interruption forever; ◎2.9-inch LCD screen display with clear visibility;
◎Five displays (temperature, humidity, brightness, time, date)
◎The APP monitors the whole process, sets the upper limit and lower limit alarm; effectively overcomes the shortcomings of the traditional can not always control;
◎Intelligently turn off / turn on the backlight / save point mode;
◎Precise detection, constant detection, every second;
◎Support external temperature sensing line (optional)
◎Support temperature unit switching at will (℉~℃), completely solve the different units in different countries;
◎Easy to install, fixed on the wall, placed on the desktop arbitrarily;
