M5Stack PIR Motion Detector PIR Sensor 0.5 m Sensor Radius China

M5Stack U004 PIR Motion Detector PIR Sensor is a compact passive pyroelectric infrared detector used for sensing human body infrared radiation within a 0.5 meter radius. It is designed to identify infrared emissions and reflections from human bodies and objects causing the sensor to trigger a high-level output signal.

The output remains high for a delay period to enable repeated triggers and adjusts back to low when the infrared signal disappears. This feature ensures reliable motion detection performance for security, automation, and safety applications.

The sensor unit interfaces with the M5Core controller through the GROVE B port, facilitating seamless integration for custom projects and embedded applications. With physical dimensions of 24 mm width, 34 mm height, and 12 mm depth, the sensor fits well into compact electronic assemblies without occupying excessive space.

The product does not include any batteries and lacks specific standards or regulatory approvals. The sensor detects infrared radiation emitted and reflected by the human body or objects. Outputs a high-level signal on infrared detection with a delay to allow repeated triggers.

Interfaces via the GROVE B connector with M5Core. Compact size: 24 mm (W) x 34 mm (H) x 12 mm (D). Designed for security alarms, automation, and motion sensing applications.

Its manufactured origin is China and the product is supplied in new condition. This PIR motion detector is ideal for laboratory, industrial, security, and embedded electronics use cases where responsive presence detection is critical.
