Digital Humidity and Temperature(DHT) PIN 1, 2, 3, 4 (from left to right)

 PIN 1- 3.3V-5V Power supply

 PIN 2- Data

 PIN 3- Null

Data pin (pin 2) can be

connected to any digital

pin

 PIN 4- Ground

digital pin

Answer 2

DHT sensor: They are low cost temperature and humidity sensors that contains a very basic chip that converts analog signals to digital signals.

It uses a capacitor and thermistor to sense the temperature and humidity.

As the sensor converts analog signals to digital signals, the data pin should be connected to the digital pin as the output of the sensor is digital.

The answer is digital pin.
