AM2302 is a discontinued sensor that measures temperature and humidity using a thermistor and a capacitive sensor. It requires a data pin and a 5V power, and has a low sampling rate of once every 2 seconds.
When AM2302 detect the start signal, AM2302 will pull low the bus 80us as response signal, then AM2302 pulls up 80us for pr eparation to send data. See below figure:-----2). Step 2 : AM2302 send data to MCU When AM2302 is sending data to MCU, every bit's transmission begin with low-voltage-level that last 50us, the
