What it does

The DHT11 Temperature and Humidity Sensor Module is a basic, low-cost digital temperature and humidity sensor. It provides calibrated digital output via a single-wire interface, making it ideal for beginners and simple weather stations.

Key features

  • Measures temperature and humidity in one module
  • Digital output via single-wire interface
  • Factory calibrated for stable readings
  • Low power consumption suitable for battery projects
  • Compact module with onboard components
  • 3-5V operation compatible with Arduino and ESP
  • No additional components needed

Good to know

  • Requires 1-second minimum between readings
  • Lower accuracy than DHT22 – consider upgrading if precision needed
  • Use DHT library (Adafruit or simpleDHT) for Arduino
  • Pull-up resistor (4.7K-10K) may be needed on data pin
  • Not suitable for freezing or very high-temperature environments
