Features 5
- WWZMDiB 5 Pcs PIR Sensor: When a human body enters the sensing range, the temperature difference between the body and the background causes a voltage change in the pyroelectric device. After amplification and comparison, the voltage signal is output.
- Voltage:DC 4.5-20V
- Detection Angle: <110 cone angle Lens size
- Detection range: 3-7 meters (10-23 feet)(adjustable)
- Two triggering modes: H: The output signal is maintained as long as a person is present. L: Triggered once with each change.

Perfect replacement sensors for my Raspberry Pi 4 dog-potty alert system!
I built a smart home system using a Raspberry Pi 4 and Picar-x so that when my dog approaches the window to go potty outside, it plays a voice alert saying "Please open the door." The previous sensor I used was way too sensitive, causing too many false alarms, so I bought this 5-pack of HC-SR501 compatible PIR sensors as a replacement. These sensors work beautifully! Since they allow you to adjust the sensitivity and time delay directly on the module, I was able to fine-tune it perfectly for my dog's movements. They integrate seamlessly with the Pi 4, and having a pack of 5 gives me great value and spares for future DIY projects.

A Passive InfraRed (PIR) sensor. Has worked great for my Raspberry Pi camera project.
The kit comes with two plexiglass mounts (with screws and bolts), 8 inch (200mm) male to female connector wires, and female to female connector wires. There is also a cute little screwdriver. The picture here shows the pinouts for connecting to a microcontroller and the two potentiometers used for adjusting ranges and sensitivity. The yellow jumper is used to select how the sensor operates. If you want the sensor to stay active all of the time when there is motion in front of it, you place the jumper on "High". If you want the sensor to detect motion and then turn off, you use the "Low" position. Mine came from the factory in the "Low" position.

Good Buy
Very nice - the stand/holder for the PIR is nice.

quality is questionable, but if they work, they work well.
Two of the five PIR sensors didn't work. The center pin output on the PIR was always HIGH (on). It is supposed to be LOW/off until motion is detected. I have wired up eight of these, with and without a microcontroller, so I know how they work. Put them on a voltmeter before building them into your project.

Good sensors
Great motion modules. Sometimes I really don't want to wait for AliExpress and found these to be similarly priced, and shipped very fast. Good value for the money, they are very sensitive (which is good) and were easy to install into my ESP32 meshtatic application.

Very poor quality.
The quality is so shoddy. It's a good thing they sell these in a 5-pack, because at least 3 will not work right. If you buy these, plan on spending an hour or so thoroughly testing every single one to make sure it works right.
