The DHT11 Sensor Relay Module is a popular and versatile component widely used in various electronic and IoT (Internet of Things) applications. Combining the simplicity of the DHT11 temperature and humidity sensor with the practical control capabilities of a relay, this module provides an effective solution for automating and monitoring environmental conditions. In this article, we will delve into the functionality, features, and common uses of the DHT11 Sensor Relay Module, highlighting its significance in real-time data monitoring and automated control.

The DHT11 Sensor: Basics and Capabilities The DHT11 sensor is a basic and affordable digital sensor that can measure temperature and humidity. It is widely used in beginner-level electronic projects due to its simplicity and low cost. The sensor operates by sensing changes in the air’s temperature and humidity, providing accurate readings of these environmental parameters. The DHT11 provides two types of data: temperature and humidity. The temperature can be measured in Celsius or Fahrenheit, while the humidity is typically given as a percentage of the total moisture in the air. Despite its affordability, the DHT11 has a reasonably good level of accuracy, with a temperature measurement range from 0°C to 50°C and a humidity range from 20% to 80%.
