It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, providing a calibrated digital signal on a single data pin. Ideal for maker projects, weather stations, and home automation, the DHT11 delivers stable readings with update rates up to 1 Hz.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V to 5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e0°C to 50°C (±2°C accuracy)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity Range\u003c\/td\u003e\n\u003ctd\u003e20% to 80% RH (±5% accuracy)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSampling Rate\u003c\/td\u003e\n\u003ctd\u003e1 Hz (once per second)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput\u003c\/td\u003e\n\u003ctd\u003eDigital signal (single-wire protocol)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e15.5mm x 12mm x 5.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-indoor-weather-station\"\u003eIndoor weather station displaying temperature and humidity on an LCD\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-fan-temperature-controller\"\u003eAutomated fan control based on room temperature\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/esp32-greenhouse-monitoring-kit-soil-and-climate-sensor-network\"\u003eGreenhouse monitoring system with alerts\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/10-sensor-environmental-data-logger-kit-for-arduino-mega\"\u003eData logger for environmental conditions using a microcontroller\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThe DHT11 works with any microcontroller capable of digital I\/O. Commonly paired with Arduino Uno, Nano, ESP8266, ESP32, and Raspberry Pi (with 3.3V or 5V tolerance). The single-wire protocol is supported by standard libraries, making integration straightforward.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect VCC to 3.3V–5V, GND to ground, and the DATA pin to a digital pin on your microcontroller. A pull-up resistor (4.7kΩ–10kΩ) between DATA and VCC is required for signal stability. Avoid long cable runs to prevent noise.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
