Key Features
- Dual Sensing: Measures both temperature and humidity with a single module, reducing component count in your project.
- Pre-calibrated Digital Output: Factory-calibrated coefficients stored in OTP memory ensure accurate readings straight out of the box-no manual calibration required.
- Simple 3-Pin Interface: VCC, DATA, and GND pins with an onboard pull-up resistor let you connect directly to any microcontroller without extra circuitry.
- Wide Voltage Compatibility: Operates from 3.3V to 5.5V, making it compatible with both 3.3V logic (ESP32, Raspberry Pi) and 5V logic (Arduino Uno, Mega) boards.
- Extensive Library Support: Works seamlessly with the widely available DHT library for Arduino IDE, MicroPython, CircuitPython, and Raspberry Pi Python libraries.
- Low Power Consumption: Draws minimal current during standby and measurement, suitable for battery-powered and solar-powered IoT deployments.
- Compact Breakout Board: Module PCB includes power indicator LED and mounting hole for easy integration into enclosures and prototypes.
- Long Transmission Distance: Signal can travel up to 20 meters of cable, enabling remote sensor placement in weather stations and greenhouse setups.

How It Works
The DHT11 module uses a capacitive humidity sensor and a thermistor to measure the surrounding air conditions. When your microcontroller sends a start signal on the DATA pin, the DHT11 responds with a 40-bit data frame containing humidity integer, humidity decimal, temperature integer, temperature decimal, and a checksum byte. The onboard controller handles all the analog-to-digital conversion internally, so you receive clean, calibrated digital data ready for processing. Popular libraries like Adafruit's DHT library abstract this protocol into simple function calls such as readTemperature() and readHumidity().
Wiring Guide
| DHT11 Module Pin | Arduino Uno | ESP32 | Raspberry Pi |
| VCC (+) | 5V | 3.3V | 3.3V (Pin 1) |
| DATA (OUT/S) | Digital Pin 2 | GPIO 4 | GPIO 4 (Pin 7) |
| GND () | GND | GND | GND (Pin 6) |
Note: The module includes an onboard 10 kOhm pull-up resist
