How it works

The DHT11 sensor uses a capacitive humidity sensor and a thermistor to measure the surrounding temperature and humidity. The sensor then outputs a digital signal that can be read by a microcontroller. This allows you to easily integrate the sensor into your projects and retrieve real-time environmental data.

Getting started

1. Connect the DHT11 sensor to your microcontroller using the provided wires.
2. Install the necessary libraries for your microcontroller (e.g., DHT library for Arduino).
3. Write a simple program to read data from the sensor.
4. Upload the program to your microcontroller.
5. Monitor the temperature and humidity readings in your serial monitor.

Wiring / connections

Connect the DHT11 sensor as follows:

1. VCC to 5V power supply
2. GND to ground
3. Data pin to a digital pin on your microcontroller

Tips & troubleshooting

1. Ensure proper connections to avoid inaccurate readings.
2. Keep the sensor away from direct sunlight for accurate temperature readings.
3. Use pull-up resistors if necessary for the data line.

Safety notes

Handle the sensor with care and avoid exposing it to moisture or extreme temperatures.
