Humidity Sensor

The Humidity Sensor project demonstrates how to use an Arduino Nano with a DHT11 sensor to measure humidity and temperature. This project is valuable for applications requiring environmental monitoring, such as climate control systems and weather stations.

Components Needed

• Arduino Nano
• DHT11 Sensor
• Jumper Wires

Circuit Diagram

Circuit Setup

1.Connect DHT11 Sensor to Arduino Nano:

Connect the data pin of the DHT11 sensor to digital pin 2 on the Arduino Nano.

Ensure proper grounding by connecting the sensor's ground pin to the Arduino Nano's ground (GND).

Connect the sensor's VCC pin to the Arduino Nano's 5V pin for power.

Instructions

1.Circuit Setup:

Wire the DHT11 sensor to the Arduino Nano as described in the circuit setup section.

2.Code Upload:

Connect the Arduino Nano to your computer via USB.

Open the Arduino IDE and paste the provided code.

Select the correct board (Arduino Nano) and port from the Tools menu.

Upload the code to the Arduino Nano.

3.Testing:

Once the code is uploaded, tap the sensor module.

Observe the humidity and temperature values displayed in the serial monitor.

Applications

Climate Control Systems: Use humidity sensors in HVAC systems for maintaining optimal indoor air quality.

Weather Stations: Incorporate humidity sensors into weather monitoring systems for collecting environmental data.

Plant Monitoring: Monitor humidity levels in agricultural settings to optimize plant growth conditions.

Notes

Ensure the DHT11 sensor is adequately positioned to avoid interference with external factors affecting humidity readings.

Calibrate the sensor if necessary for accurate humidity and temperature measurements.

Implement error handling in the code to handle sensor communication failures or anomalies.
