The DHT11 Humidity And Temperature Sensor Module measures both air temperature and relative humidity (the amount of water vapour in air compared to its maximum capacity) from a single digital output pin. The dht11 humidity and temperature sensor operates on 3.3V to 5V DC and covers a temperature range of 0°C to 50°C with a humidity range of 20 to 95 percent RH. An onboard LED confirms active power at a glance.
The dht11 humidity and temp sensor uses a resistive humidity element (a component whose electrical resistance changes as it absorbs moisture from surrounding air) paired with a thermistor (a temperature-sensitive resistor). One non-obvious detail — the DHT11 can only update its reading once per second. Polling it faster returns the same old reading, not a fresh measurement. The honest limitation is accuracy at plus or minus 5 percent RH and plus or minus 2°C, which suits trend monitoring better than precise measurement.
The dht11 humidity sensor makes it a popular first sensor for students and hobbyists. The dht11 temperature and humidity sensor 3 pins connects to Arduino, ESP32, and Raspberry Pi GPIO pins. Connect VCC, GND, and data, install the DHT library in Arduino IDE, then run the example sketch. StemVolt provide sensor module tested for confirmed digital output at rated voltage.
