In the world of electronics and automation, integrating sensors with relay modules provides a perfect solution for creating smart systems that can automate various tasks based on environmental parameters. One of the most common sensor and relay module combinations is the DHT11 Sensor Relay Module. This setup is often used in simple automation projects, especially in home automation and IoT (Internet of Things) applications. In this article, we will explore the functionality, applications, and benefits of using the DHT11 Sensor Relay Module.
What is the DHT11 Sensor? The DHT11 is a low-cost, digital temperature and humidity sensor commonly used in many electronics projects. It measures the surrounding temperature and humidity levels and outputs the data to a microcontroller (like an Arduino or Raspberry Pi) in a digital format. The DHT11 is particularly popular for beginner-level projects because of its simple interface and affordability. Key Features of DHT11 Sensor： Temperature Range： 0 to 50°C with a precision of ±2°C. Humidity Range： 20% to 90% RH (Relative Humidity) with a precision of ±5%. Output Type： Digital (One-wire communication).
