Description

The DHT11 Digital Temperature & Humidity Sensor Module is a popular, beginner-friendly sensor for measuring ambient temperature and relative humidity in DIY electronics projects. It combines both readings in one compact board and outputs the data digitally using a simple single-wire protocol, making it easy to integrate with Arduino and Raspberry Pi projects using widely available libraries.

This module is perfect for basic environmental monitoring such as room climate tracking, small DIY weather stations, greenhouse monitoring, IoT prototypes, and educational STEM projects. Because it’s a module (not just the bare sensor), it typically includes the needed resistor/pull-up and pins for quicker prototyping.

Key Features & Benefits

Two-in-One Sensor: Temperature + humidity readings from a single module
Digital Output: Stable signal without analog noise and easy microcontroller reading
Simple Wiring: 3-pin interface for quick breadboard and jumper-wire setups
Wide Power Range: Works on 3.3V and 5V power systems
Library Support: Supported by common Arduino and Raspberry Pi libraries
Great for Learning: Ideal for beginners, classrooms, and quick prototypes

Typical Specifications

Item	Typical Value
Sensor	DHT11
Measurements	Temperature + Relative Humidity
