DHT11 Digital Temperature and Humidity Sensor Module for Arduino

DHT11 Digital Temperature and Humidity Sensor Module for Arduino

Monitor environmental conditions with the popular and cost-effective DHT11 Digital Temperature and Humidity Sensor. This module is a go-to choice for hobbyists and students looking to create basic weather stations, climate control systems, or any project that requires ambient temperature and humidity readings.

The DHT11 is a composite sensor that contains a calibrated digital signal output for both temperature and humidity. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air. An internal 8-bit microcontroller handles the measurements and provides a clean, single-wire digital signal, making it incredibly easy to use with microcontrollers like Arduino. Simply connect power, ground, and a single data pin to start getting readings.

This sensor is pre-calibrated in the factory, ensuring good reliability and excellent long-term stability. It’s the perfect entry-level sensor for a wide range of applications.

Key Features:

• Dual Function: Measures both relative humidity and temperature.
• Digital Signal: Provides a fully digital output, eliminating the need for analog conversion.
• Operating Range: 20-90% RH for humidity and 0-50°C for temperature.
• Accuracy: +/- 5% RH for humidity and +/- 2°C for temperature.
• Simple Interface: Uses a single data wire for communication.
• Operating Voltage: 3V to 5V.

Applications:

Ideal for building DIY weather stations, home automation systems for HVAC control, environmental monitoring for greenhouses, humidity regulators for incubators, and various educational science projects.
