PRODUCT DETAILS
PIR(Passive Infrared Sensor) sensor is used for making motion detecting applications such as alarm burglar systems, visitor presence monitoring, light switches and robots. The Grove – mini PIR motion sensor is a compact, low power consumption and cost effective PIR sensor which is suitable for applications with relatively less detection distance requirement.
The detection distance in the datasheet is up to 3m to 5m, however 2m is the best detection distance that we recommend and 25℃ is the most suitable temperature.
The sensitivity of the sensor is adjustable, there is reserved pin out on the back of the board so that you can solder a slide rheostat to adjust the sensitivity. If you think the sensitivity is not enough, here is a trick, drag the plastic cap a little up will help enhance the sensitivity.
The PIR Motion Sensor Series includes several products that will meet your different needs:
| Product | Measuring range (theoretical value) | Features |
|---|---|---|
| Grove - PIR Motion Sensor | Max Distance:3-6m(3m by default) Angle:< 120° |
Measuring distance and holding time adjustable response speed:0.3s - 25s |
| Grove-Adjustable PIR Motion Sensor | Max Distance:3-6m Angle:X=110° Y=90° |
Measuring distance and holding time adjustable |
| Grove - mini PIR motion sensor | Max Distance:2-5m(2m by default) Angle:X=110° Y=90° |
Sensitivity adjustable Mini-size |
| PIR Motion sensor module | Max Distance:3-7m Angle:< 120° |
Sensitivity & Delay time adjustable |
| Grove - Digital PIR Motion Sensor | Max Distance: 3-12m Angle:< 100° |
Mini-size Simple and intuitive |

from order viewDocumentation is good. It's easy to hook up and use, but the sensitivity is fairly hit-or-miss. As this was my first Arduino project, I didn't buy the best, and it works well enough for playing around.
