The DHT11 Temperature & Humidity Sensor is a digital sensor that measures both ambient temperature and relative humidity. It operates on 3.3–5 V and delivers calibrated digital readings with a 1 Hz sampling rate. With ±2 °C temperature accuracy and ±5 % RH stability, it’s ideal for weather stations, HVAC systems, plant monitoring, and IoT projects. Compatible with Arduino, ESP32, and Raspberry Pi, it offers easy integration with a pull-up resistor and one-wire data output.
