Key Features of DHT 11 Module
- Ready-to-Use Module: On-board 4.7kOhm pull-up resistor and power LED - no extra components needed; connect directly to your microcontroller with just 3 wires.
- Simple Digital Interface: Single-wire data protocol requires only one GPIO pin, freeing up I/O for other sensors and peripherals.
- Wide Voltage Compatibility: Operates from 3.3V to 5.5V, making it natively compatible with both 3.3V boards (ESP8266, ESP32, Raspberry Pi) and 5V boards (Arduino Uno, Mega, Nano).
- Low Power Consumption: Draws minimal current during standby and measurement, ideal for battery-powered and solar-powered applications.
- Factory Calibrated: Each sensor is individually calibrated at the factory with calibration coefficients stored in OTP memory - no manual calibration required out of the box.
- Compact PCB Design: Mounting holes and standard 2.54mm pin headers allow easy breadboard prototyping or permanent PCB integration.
- Extensive Library & Community Support: Thousands of tutorials, example codes, and community projects available for Arduino IDE, MicroPython, CircuitPython, and PlatformIO.
- Reliable Long-Term Stability: Proven resistive sensing element offers consistent readings over extended deployment periods with minimal drift.
DHT11 Temperature & Humidity Sensor Module
Accurately measure ambient temperature and relative humidity with the DHT11 sensor module - a reliable, easy-to-use digital sensor perfect for weather stations, home automation, and IoT projects. Available at Tech Depot India, Bengaluru, with fast shipping and full technical support.
How It Works
The DHT11 module uses a resistive-type polymer humidity sensor and an NTC (Negative Temperature Coefficient) thermistor to measure relative humidity and ambient temperature respectively. When your microcontroller sends a start signal on the DATA pin, the DHT11 responds with a 40-bit data frame containing 8-bit integer humidity, 8-bit decimal humidity, 8-bit integer temperature, 8-bit decimal temperature, and an 8-bit checksum for error verification. The on-board pull-up resistor ensures a stable HIGH state on the data line when idle. Popular libraries like the Adafruit DHT library handle the precise timing and parsing automatically, letting you read temperature and humidity values with just a few lines of code.
