DHT11 Temperature Humidity Sensor Module

Description

The DHT11 is a digital temperature and humidity sensor that uses a capacitive humidity sensor and an NTC thermistor to measure the surrounding air. The capacitive humidity sensor consists of two electrodes with a moisture holding substrate as a dielectric between them. As the humidity levels change, the capacitance of the sensor changes. The NTC thermistor is a resistor whose resistance decreases as the temperature increases.

Here are some of the advantages of using the DHT11 sensor:

Low cost
Easy to use
Single data pin
One-wire protocol
Wide temperature and humidity range
Good accuracy

DHT11 Temperature Humidity Sensor Pin Descriptions : –
The DHT-11 digital temperature and humidity sensor has 4 pins:

VCC: The VCC pin is the power supply pin for the sensor. It should connect to a voltage source of 3.3V to 5.5V.
DATA: The DATA pin is the data pin for the sensor. It used to communicate with the sensor using the one-wire protocol.
GND: The GND pin is the ground pin for the sensor. It should connect to a common ground.
NC: The NC pin is not connected to anything. It typically left unconnected.
