Winsen PIR Motion Sensor

The full name of PIR sensor is Passive Infrared Sensor, we also call it PIR motion sensor. PIR sensors can detect infrared rays radiated by living bodies in a non-contact form. It is usually used to detect whether the living body is moving within the detection range.

Winsen has more than ten kinds of PIR motion sensors, you can choose them according to the function or application.

You can buy our PIR motion sensor on Alibaba, AliExpress. Or contact us directly, no quantity limit.

Advantages of PIR Sensors

Good Selectivity

Strong Anti-Interference

Anti-small animal, electromagnetic, light interference

High Sensitivity

Low Cost

TO-5 package, saving time in circuit design and placement

Small and Portable

Various Options

Digital, Analog, Modular

Simple Structure

Good Concealment

Small size, small volume

Discuss the detection distance range of PIR motion sensor

No matter what application the PIR motion sensor is used in, we will pay attention to the maximum distance that the product can detect. The PIR motion sensor needs to be used with a Fresnel lens. The test distance is related to the lens. There are 5 meters, 8 meters and further distance options.

If you need, we can provide lens for sale together.

How to choose the right PIR motion sensor?

How to choose the right PIR motion sensor

We have 3 types of PIR motion sensors: Analog Pyroelectric, Digital Pyroelectric and Fresnel Lens Module. RD623, RD624, and RD626W are all analog PIR sensors. The difference in window size is the only difference between RD623 (3.8*5mm) and RD624 (3*4mm). From the perspective of stable performance, RD626W is the best.

If you want to save time on designing circuits, you can choose our digital PIR sensors (RDA, RDB series).

We can also provide Fresnel lens modules, you just need to tell us the focus, angle and distance you need. Welcome to contact us.

How PIR motion sensors become one of the sensing layers of IoT systems

PIR motion sensors can be used to control hallway lights or any other areas that don't need constant light to save electricity. The basic component of this type of smart sensing is the sensor.

Taking the smart home field as an example, when the PIR motion sensor receives an intrusion signal, it can immediately activate the smart door lock, and the smart camera will automatically take pictures to obtain evidence and send an alarm message. The new smart home system is changing our future.

PIR Motion Sensor Guide

We have summarized the following questions to help you make better choices.


How does a PIR sensor work?


PIR sensors can sense motion. They are used to detect whether a person enters or leaves the range of the sensor. Commonly found in appliances and gadgets used in the home, business, or business. They are often called PIR, "passive infrared", "pyroelectric" or "IR motion" sensors.


Can a PIR motion sensor work all day or under lights?


Yes. Winsen PIR motion sensor has strong anti-interference performance. In addition, it can prevent small animal interference and anti-electromagnetic interference.


Why is the PIR motion sensor unresponsive during the test?


1. The person is not moving.

2. Exceeding the sensing angle and distance (normally configured Fresnel lens can detect 15 meters).

3. There is a problem with the sensor itself and needs to be replaced in time.


What are the applications of PIR motion sensors?


Smart office appliances; family, smart home;

Automatic lighting switch, security door; security, intrusion alarm, indoor access management;

Security products; human sensor toys; human sensor lamps, switches, home appliances; industrial automation control


Are there any requirements for PIR motion sensor installation?


Please pay attention to the window direction of the sensor when designing the product, combining with the Fresnel lens can achieve an ideal detection angle. Frequent and excessive vibration will cause the sensitive body inside the sensor to break, so handle it with care.
