PIR/ Motion Sensors sense moving objects and people. They are often integrated with projects, robots and work as a part of the complex system. The PIR (Passive Infra-Red) Sensor is a pyroelectric device that detects motion by measuring changes in the heat levels emitted by surrounding objects.
We have picked for you 10 best motion sensors that you can integrate with your Raspberry Pi. Read on.
10. ELEGIANT HC-SR505 ($5.99)
ELEGIANT HC-SR505 is a mini sensor which consists of infrared sensor, motion sensor and infrared detector module. It has a range of 4 meters. Used also in body sensor toys. Battery powered and has the ability to automatically sense signals.
9. Aukru HC-SR501 ($5.99)
These sensors are used in automation and control. This sensor is ideal to be used with Raspberry Pi and arduino. Its response time is pretty fast since it quickly opens whatever output is attached. Especially suitable for hotels, shopping malls, warehouses, corridors and other sensitive regions.
8. Adjust IR Pyroelectric Infrared IR PIR Motion Sensor Detector Module HC-SR501 ($6.60)
Automatic sensor. Turns ON when someone enters the range and turns OFF when someone leaves the range. It has a photosensitive control and two trigger modes: Do not repeat the trigger, repeat the trigger. It also has a photosensitive control and compensates for temperature.
7. HC-SR501 Adjust Infrared PIR Motion Sensor Detector Module ($8.99)
This is also an automatic sensor where it turns ON and OFF itself. It has a slightly short detection range and similar to the previous sensor in this list, has 2 modes of trigger: Repeatable and do not repeat the trigger. You can also setup induction blocking time where sensor takes in no signal for that time period.
6. ALSRobotBase PIR Sensor for Arduino ($10.39)
This is a passive infrared sensor and requires 3 – 6V direct current. The operating temperature range is 0 – 50 celsius.
5. Triple Axis Accelerometer BMA220 ($12.66)
It has an I2C interface and low power LED indication. Compact design with easy to use hardware. This is compatible with Arduino and Raspberry Pi. This sensor allows measurement in 3 perpendicular axes thus sensing tilt, motion, shock.
4. HC-SR501 PIR Motion Detection Modules ($14.99)
This is a 3 in 1 sensor kit with all 3 HC-SR501 PIR motion detectors. This kit comes with GPIO card which wires with Pi. It works on 5V and has an adjustable range and dwell times. It has a range of 5-7 meters.
3. PIR (Motion) Sensor for Arduino Compatible ($16.66)
This is compatible with both Arduino and Raspberry Pi. Used in human body detection and security systems. Compact, easy to use PIR sensor and infrared sensor. Mostly found in gadgets because they do not wear soon.
Highly reliable and low power consumption.
2. PIR (Motion) Sensor/Moving Human Detection/Occupancy Detection/Security Systems ($16.66)
It has a working temperature of -20 ~ 85 ? and output voltage which ranges between 0 – 3V. It has a range of 7 meters and detection angle of 100 degrees. Compatible with Arduino UNO/DUO and Raspberry Pi.
1. EMY 5 X HC-SR501 Adjust Ir Pyroelectric Infrared PIR Motion Sensor Detector Modules ($4.50)
5 in 1 HC-SR501 by Tonsee. These have an operating voltage of 5 – 20V. Output swings between 0 – 3.3V. Adjustable delay time of 0.3 to 18 seconds.
Around 64% of 195 customers rated it 5 stars. You can power them from 3.3V. Simple to implement and very effective to use. One trim pot adjusts trigger threshold, and the other adjusts time.
