Recently, sensors have become an indispensable option in many projects. There are many different ways of installing the sensor. Today, I will share a case in Flood light with PIR Sensor.
Customers need the PIR sensor installed onto the Flood light, glass opening, and close to chips. But we normally do not recommend this way, when comes to the PIR sensor. Why?
Let’s see how it works of PIR sensor
A PIR (Passive Infrared) sensor detects changes in infrared radiation emitted by objects. It uses a pyroelectric material that generates an electric charge when exposed to temperature changes. By measuring the difference in infrared radiation between two segments, the sensor detects motion and triggers an output signal for various applications like security systems and automatic lighting control.
As you can see. PIR sensor detects objects based on the temperature change. When the PIR sensor is too close to the LED Chips that release heat, it will affect the judgment of the surrounding temperature difference, resulting in inaccurate detection.
So how do we install it? Like this way:
Any questions, welcome to consult me.
