Digital Humidity and Temperature Sensor Module (DHT11)

The DHT11 is a basic low-cost digital humidity and temperature sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and provides a digital signal on the data pin. It’s fairly simple to use but requires careful timing to grab data, you can only get new data from it once every 2 seconds.

This module is an implementation of the popular low-cost DHT11 sensor. It comes with proper headers to make it even easier to connect to any exposed pins of your development board.

  Features :

• Operating voltage: 3V ~ 5V.
• Humidity measurement ranges from 20%~80% with ±5% accuracy.
• Temperature measurement range 0°C ~ 50°C with ±2°C accuracy.
• Interface: One-wire communication protocol.
