understanding the dht11 sensor relay module: an introduction to its functionality and applications
Release time:2025-05-14 20:25:23
The DHT11 Sensor Relay Module is an essential component used in various projects involving automation and monitoring systems. This module combines the DHT11 temperature and humidity sensor with a relay, which allows it to control and monitor devices based on environmental conditions. Its simplicity, cost-effectiveness, and wide range of applications make it an ideal choice for both hobbyists and professionals in fields like home automation, weather stations, and agriculture.
What is the DHT11 Sensor?
The DHT11 sensor is a widely used device designed to measure temperature and humidity levels in the surrounding environment. It uses a capacitive humidity sensor and a thermistor to detect these two crucial parameters. The sensor has a digital output, making it easy to interface with microcontrollers like Arduino or Raspberry Pi.
While the DHT11 is not as precise or fast as some other temperature and humidity sensors, its affordability and sufficient accuracy for many basic projects make it highly popular. The temperature range of the DHT11 sensor is between 0°C and 50°C with an accuracy of ±2°C, and it can measure humidity in the range of 20% to 80% with an accuracy of ±5%.
