Release time:2025-10-22 18:24:21

    The DHT11 Sensor Relay Module is a widely used combination of two important components in the world of IoT (Internet of Things) and embedded systems. It consists of the DHT11 temperature and humidity sensor and a relay module that can control high-voltage devices using low-voltage signals. This module offers an affordable and effective solution for various applications that require temperature and humidity monitoring and control. In this article, we will explore the DHT11 Sensor Relay Module's working principles, applications, and how it can be used in real-world projects.

DHT11 Sensor Relay Module

    What is the DHT11 Sensor?
    The DHT11 is a digital temperature and humidity sensor that is commonly used in Arduino, Raspberry Pi, and other microcontroller-based projects. It provides a simple and cost-effective way to measure environmental conditions. The sensor uses a capacitive humidity sensor and a thermistor to measure the ambient temperature and humidity levels.
    The DHT11 sensor operates in the following ranges:
    Temperature range: 0 to 50°C with an accuracy of ±2°C.
    Humidity range: 20% to 90% RH (Relative Humidity) with an accuracy of ±5% RH.
    It is important to note that the DHT11 sensor is less accurate and has a narrower range compared to more advanced sensors like the DHT22, but it is often more than sufficient for basic applications such as DIY home automation projects or simple environmental monitoring systems.
