HD3014 display temperature (1 channel 32.3 ° C)
HD3014 display humidity (2 channels 46.4% RH)
The wall-mounted temperature and humidity sensor probe uses the SHT10 temperature and humidity sensor imported from Sensirion, Switzerland. The sensor uses a digital interface to output a fully calibrated digital signal. It can be completely interchanged without calibration.
The TVS diode is used inside the module to prevent accidental burning of the chip.
Installation method: wall-mounted installation.
