The DHT11 Sensor Relay Module is a highly versatile and useful component in the world of electronics and automation. It combines a temperature and humidity sensor with a relay module to offer a complete solution for controlling and monitoring environmental conditions. This module is frequently used in various applications such as smart homes, weather stations, and automated systems that require temperature and humidity control. In this article, we will delve into the functionality, applications, and potential uses of the DHT11 Sensor Relay Module.
Understanding the Components Before diving into the applications of the DHT11 Sensor Relay Module, it is important to understand its individual components and how they work together. 1. DHT11 Sensor The DHT11 is a popular digital temperature and humidity sensor that is often used in low-cost environmental monitoring projects. It measures the temperature in the range of 0°C to 50°C with a tolerance of ±2°C and the relative humidity from 20% to 80% RH with a tolerance of ±5% RH. The sensor uses a capacitive humidity sensor and a thermistor to measure the temperature and humidity in the surrounding environment. The sensor outputs a digital signal, making it easy to interface with microcontrollers such as Arduino or Raspberry Pi.
