Release time:2025-12-10 23:52:12
In the world of electronics and home automation, the integration of sensors and relays plays a critical role in creating efficient, automated systems. One of the most widely used sensors in these projects is the DHT11, a basic yet reliable temperature and humidity sensor. When combined with a relay module, the DHT11 can be used to control various appliances based on environmental conditions. In this article, we will explore the functionality, applications, and potential uses of the DHT11 Sensor Relay Module in home automation systems.
What is the DHT11 Sensor?
The DHT11 sensor is a low-cost, digital temperature and humidity sensor that is widely used in DIY electronics and home automation projects. It measures the ambient temperature and relative humidity in its surrounding environment and converts these measurements into a digital signal. The sensor has a relatively narrow measurement range, but it is accurate enough for many applications, particularly in non-critical environments.
Temperature Range： 0°C to 50°C (±2°C accuracy)
Humidity Range： 20% to 90% RH (±5% RH accuracy)
The sensor communicates via a single-wire digital protocol, which makes it easy to interface with microcontrollers like Arduino, Raspberry Pi, and other platforms. Its compact size and affordability make it a popular choice for hobbyists and professionals alike.
