Release time:2025-05-07 11:12:18
The DHT11 sensor is a widely used electronic component that can measure temperature and humidity in a variety of applications. When combined with a relay module, the DHT11 Sensor Relay Module becomes a powerful tool for controlling devices based on environmental conditions. This article aims to provide a detailed explanation of the DHT11 sensor, how it works, the role of the relay module, and how to use the DHT11 Sensor Relay Module in practical projects.
What is the DHT11 Sensor?
The DHT11 sensor is a digital sensor that can measure both temperature and humidity levels in the environment. It is a low-cost, reliable, and easy-to-use sensor that provides accurate readings for basic applications. The DHT11 sensor consists of a thermistor and a capacitive humidity sensor, which work together to provide real-time data on temperature and humidity.
The temperature measurement range of the DHT11 sensor is between 0 to 50°C, with an accuracy of ±2°C. The humidity measurement range is from 20% to 80% RH (Relative Humidity), with an accuracy of ±5%. Although the DHT11 sensor has relatively lower accuracy compared to other high-end sensors, it is more than sufficient for many hobbyist projects, weather stations, and home automation systems.
