Grove Digital PIR Motion Sensor 12m

The Seeed Studio Grove Digital PIR Motion Sensor detects infrared radiation from moving objects up to 12 metres away. It outputs a simple high or low digital signal in under one second for immediate motion detection. The module uses a standard Grove unified socket for direct connection to compatible controllers. It is designed for quick integration into security or automation projects.

Makers needing a plug-and-play motion detector

This sensor suits hobbyists and developers building Arduino or Raspberry Pi projects that require presence detection within a 3.2 to 12 metre range. The digital output and Grove interface allow fast prototyping without soldering or complex wiring. Buyers who need analogue signal output, adjustable sensitivity settings, or detection beyond 12 metres should consider alternative sensor types. Applications requiring environmental protection ratings not listed here will need additional housing.

12 metre detection range

The maximum detection distance of 12 metres is the key specification that determines if this module fits the intended coverage area. The sensor operates effectively from a minimum distance of 3.2 metres up to this limit. This range defines the spatial constraints for security zones, lighting triggers, or interactive installations. Verify that the monitored area falls within these boundaries before selecting this part.

Questions about this item

What Grove interface does the sensor use and what signal level does it output?

It uses a Grove unified socket and outputs only high and low digital signals.

What physical space does the sensor need for its detection range?

It detects motion from 3.2 m to 12 m in front of the sensor.

How do I connect the sensor to an Arduino or Raspberry Pi and what is the common mistake?

Plug the Grove cable into the unified socket; the common mistake is forgetting to set the GPIO pin as a digital input.
