I am looking at using the Humirel sensor HTG3515 with an ESP32 Wroom-32D, but I am not understanding how to connect it, if possible. I’ve included the pin out assignment for the sensor below. So far, I have connected it thus:
2.VCC-5V (also tried 3.3V)
I thought it would be enough to connect 3 and 4 to any ADC pin, but it seems not. Does anyone know how it should be connected?
Also, I have done the reading with
mgos_adc_read_voltage(). I thought this ought to be enough, i.e. no special library?
