The DHT11 Sensor Relay Module is a popular electronic setup used for controlling environmental conditions, specifically temperature and humidity, in various applications. This combination of a temperature and humidity sensor (DHT11) with a relay module enables users to create automated systems that can manage devices based on real-time environmental data. This article explores the working principles, features, and potential applications of the DHT11 Sensor Relay Module, and its significance in modern automation.
The DHT11 Sensor： Overview and Functionality
At the heart of this module is the DHT11 sensor, a low-cost digital sensor designed to measure temperature and relative humidity. The DHT11 is widely used in hobbyist projects and prototyping for its simplicity and ease of use with microcontrollers like Arduino, Raspberry Pi, and ESP32.
Key Features of DHT11：
Temperature Range： The DHT11 can measure temperatures in the range of 0°C to 50°C, making it suitable for most indoor applications.
Humidity Range： It measures relative humidity from 20% to 80% with an accuracy of ±5% RH.
Digital Output： The sensor communicates with the microcontroller using a single-wire digital protocol, making wiring simpler and reducing the number of pins needed.
