The DHT11 sensor is a basic but cost-effective sensor suitable for applications where moderate accuracy is sufficient. It provides temperature and humidity readings in a digital format, making it easy to interface with microcontrollers and other digital systems. However, please note that the DHT11 sensor has lower accuracy and a slower response time compared to more advanced sensors like the DHT22 or the SHT series sensors.

    Usage

    • The DHT11 sensor has three pins: VCC, Data, and GND.

    • VCC (or VDD): Connect this pin to the positive supply voltage, typically 3.3V or 5V, depending on the operating voltage of your system.

    • Data: This pin is used for communication with the sensor. Connect it to a digital input/output (I/O) pin of your microcontroller or development board.

    • GND: Connect this pin to the ground (0V) of your system.
