Pir Sensor Overview
A PIR sensor is also known as a passive infrared sensor and is a sensor that is electronic.
And various lights that are infrared can be measured from it and the light that radiates from the objects as well in the view of the field.
They are used in the detectors of PIR-based motions.
The sensors of PIR are used in the alarms of security and in the applications of automatic lighting as well.
Best products of Pir Sensor
Some of the best products of Pir sensor are as follows;
- HC-SR501 PIR Pyroelectric IR Infrared Motion Sensor
- Qunqi 10pack HC-SR501
- Grove – PIR Motion Sensor
- LEDENET® 12V 24V PIR Sensor

HC-SR501 PIR Pyroelectric IR Infrared Motion Sensor
The range of detection for this sensor is 7, and a power that is required by it is approximately 5V.
This sensor of rudimentary works on one’s projects in a splendid way and is one of the most excellent Pirs for working on projects.
Qunqi 10pack HC-SR501
The deals of value for this sensor of air has one of the best deals of values and works in an extremely well way for the modes of trigger that are in two amount.
It is non-repeatable and repeatable as well.
The sensors have a voltage of operating between the ranges of 4.5 and 60V.
Grove – PIR Motion Sensor
It is one of the most excellent sensors for connecting with one’s board of Raspberry Pi of Arduino as well, and it has connectors that are large.
The range of voltage is between the ranges of 3-5V, and the angle of detecting is at 120 degrees.
Adafruit PIR Motion Sensor
A sensor of Pir that is compact can be set on the hardware.
After the pins of headers, it is very easy for the sensor to be attached to the boards.
Pros of Pir Sensor
- Motions can be detected reliably indoors during the dark and day as well.
- As compared to the sensor of the microwave, less energy can be consumed by it.
- As compared to the sensors of microwaves, they are cheaper.
- For the applications that are electrical, it is good in premises that are compact and small.
Cons of Pir Sensor
- The sensitivity is low, and the coverage is less as well as compared to the sensors of the microwave.
- Greater than a temperature of 35 degrees C, it can operate.
- For the line of sight, it can operate, and for the corner regions, it will have problems as well.
- It is easier for thieves to find a range of detection of Pir.
Conclusion
The Pir sensors are used by individuals all Pakistan.
