DHT11 Digital Temperature & Humidity Sensor

The DHT11 is an entry-level digital temperature and humidity sensor, perfect for beginners experimenting with Arduino or other microcontrollers. It communicates via a single-wire digital protocol and requires only one digital pin per sensor, making integration into DIY projects simple and straightforward.

Specifications:

• Temperature range: 0°C to 50°C
• Temperature accuracy: ±2°C
• Temperature resolution: 1°C
• Humidity range: 20–90% RH
• Humidity accuracy: ±5% RH
• Response time: 1–2 seconds
• Interface: Single-wire digital
  

For projects requiring slightly higher accuracy or outdoor use, you might also consider the DHT22 (AM2302). Both sensors are compared in our Best Arduino Digital Temperature Sensors guide.
