Sensore di movimento PIR Panasonic EKMC1603112 3–6V rilevatore a infrarossi passivo per rilevamento presenza

Panasonic EKMC1603112 is a compact passive infrared (PIR) motion sensor engineered to operate from 3–6V. The detector senses changes in infrared radiation caused by moving warm objects and provides a simple, low‑power occupancy sensing interface for lighting control, alarm inputs and embedded automation. Its small form factor and straightforward electrical requirements make it suitable for integration into security panels, standalone sensors and smart building nodes where reliable motion detection is required.

Advantages

The sensor delivers reliable detection of human presence using passive infrared technology while consuming minimal power at 3–6V supply. Its compact design enables installation in space‑constrained applications and integration on custom PCBs or modules. The device provides a straightforward output suitable for direct connection to microcontrollers, alarm systems or lighting control inputs, reducing the need for additional signal conditioning. Panasonic's manufacturing and quality control ensure consistent performance over typical operating conditions.

Suitable for

• Occupancy detection for automatic lighting control
• Intruder alarm and perimeter detection systems
• HVAC presence sensing and energy‑saving automation
• Embedded IoT devices and smart home modules
• Battery‑powered or low‑voltage security panels

Key specifications

• Operating voltage: 3–6 VDC
• Detection type: Passive infrared (PIR)
• Power consumption: low‑power operation suitable for battery applications
• Output: motion detection signal compatible with microcontrollers and alarm inputs
• Physical: compact package intended for PCB mounting or module integration

How to use

Mount the sensor on a stable surface or PCB with a clear field of view towards the monitored area. Connect the supply voltage within the specified 3–6V range and wire the output to the input of a microcontroller, alarm panel or lighting controller. Positioning should avoid direct exposure to heat sources, rapid air flows or reflective surfaces that could affect infrared detection. Validate detection coverage and sensitivity in the intended installation environment and adjust sensor placement to optimise coverage.

Recommendations

For best results, install the PIR sensor at typical human height (around 1.8–2.5 m) with an unobstructed view of the monitored zone; avoid pointing towards HVAC vents, windows with direct sunlight, or infrared heat sources. When used in battery‑powered devices, implement wake/sleep control and debounce logic in the host controller to reduce false triggers and extend battery life.
