• Automated lighting control in residential and commercial spaces
• Occupancy detection for energy management systems
• Security and intrusion detection subsystems
• Embedded electronics and IoT projects requiring PIR sensing
• Appliances and equipment with presence-triggered functions

Key specifications

• Detection principle: Passive infrared (PIR) sensing
• Supply voltage: 3–6 V DC
• Output type: Motion-detection signal suitable for control circuits (details depend on implementation)
• Form factor: Compact single-unit sensor for PCB or module integration
• Typical applications: Occupancy detection, lighting automation, security

How to use

Install the EKMC1604112 according to your device’s PCB layout and wiring conventions, ensuring a stable 3–6 V DC supply and appropriate signal connections to the control circuitry or microcontroller input. Position the sensor so its field of view covers the area where motion detection is required and avoid placing obstructions directly in front of the sensor element. When powered, the PIR element detects changes in infrared radiation and produces a motion signal; interpret and debounce this signal in firmware or hardware as needed to suit your application’s timing and sensitivity requirements.

Recommendations

For reliable operation, mount the sensor to provide an unobstructed view of the monitored zone, minimize rapid temperature variations near the sensor, and apply appropriate signal filtering or software debouncing to reduce false triggers. Verify the supply voltage is stable within the 3–6 V range and consult design guidelines for the host system to adapt output signal handling and power management.
