About this item

The DHT11 Digital Relative Humidity and Temperature Sensor Module is a budget-friendly, pre-calibrated sensor ideal for basic environmental monitoring projects. It detects ambient humidity and temperature and outputs readings directly via a digital signal on a single data pin, simplifying integration with microcontrollers like Arduino or Raspberry Pi. Operating at 3.3 V to 5 V, the module features an onboard 8-bit microcontroller and pre-installed components such as an LED, bypass capacitor, and pull-up resistor—further easing setup. Humidity is measured in the 20%–95% RH range with an accuracy of ±5% RH, while temperature spans 0 °C to 50 °C with ±2 °C accuracy. The sensor updates readings approximately every 2 seconds (0.5 Hz).
