2. DHT22 Temperature and Humidity Sensor

2.1. Connecting resistor to DHT22 To start off with the DHT22 sensor, you first need to connect the first two pins (left to right direction) with a 10kΩ resistor. Same as in the previous step, use resistor legs and wrap them around the two sensor legs (just make sure they are touching each other).Af
