Product Description
A highly popular, low-cost digital temperature and humidity sensor module, ideal for climate monitoring and environmental data logging in Arduino and ESP32 projects. This module integrates a resistive-type moisture measurement component and an NTC thermistor, paired with a high-performance 8-bit microcontroller that outputs calibrated digital data. It breaks out the standard raw DHT11 sensor onto a convenient 3-pin PCB that includes an onboard pull-up resistor and filtering capacitor, enabling direct plug-and-play wiring without external components. Delivering a single-wire digital signal that is highly resistant to interference over long cable runs, this module provides an easy-to-implement solution for indoor weather stations, automated terrariums, and home climate control systems.
Pinout / Layout Connections
The module breaks out its tracking and power interface via a standard 3-pin male header block:
-
VCC Pin: Power supply input, accepts DC +3.3V to +5V.
-
DATA Pin: Single-wire bidirectional digital data line. Connects directly to a digital I/O pin on the microcontroller.
-
GND Pin: Connects to the common system ground (0V) reference.
Applications
-
Indoor Weather Stations: Perfect for building simple desktop environmental monitors, clock-displays with climate readout, and local data loggers.
-
Greenhouse & Terrarium Control: Excellent for monitoring humidity and temperature baselines to maintain healthy conditions for plants or reptiles.
-
HVAC Smart Automation: Ideal for triggering cooling fans, ventilation systems, or humidifiers based on real-time room atmosphere profiles.
Compatibility
The DHT11 Module utilizes a specific single-wire serial protocol, making it universally supported across major development platforms:
-
Arduino Board Series (Uno, Nano, Mega, Pro Micro) using native timing and standard
DHT.hlibraries from Adafruit. -
ESP32 and ESP8266 boards (Fully compatible with 3.3V digital input lines without logic conversion).
-
Raspberry Pi and Raspberry Pi Pico (Easily interfaced using Python or MicroPython DHT libraries).
