DHT11 Temperature and Humidity Sensor
DHT11 Digital Relative Humidity and Temperature Sensor Module
The DHT11 is a low-cost digital sensor that measures both temperature and relative humidity. It uses resistive sensing technology and an NTC thermistor to deliver calibrated digital output via a single data pin. The module is pre-assembled on a breakout board for easy integration with microcontrollers like Arduino.
It’s ideal for:
- HVAC systems and weather stations
- Home automation and consumer electronics
- Medical devices, dataloggers, and humidity regulators
The sensor updates readings every 2 seconds and includes onboard components like a pull-up resistor, bypass capacitor, and LED indicator.
