Sensor de movimiento PIR Panasonic EKMC1601111, detector infrarrojo pasivo, alimentación 3–6 V

Panasonic EKMC1601111 is a passive infrared (PIR) motion sensor designed to detect human presence and movement. The sensor operates from a low-voltage 3–6 V supply, offering compact, low-power performance suitable for integration into alarm systems, lighting control units and energy-saving automation circuits. Its form factor and electrical characteristics make it appropriate for indoor installations where reliable presence detection is required and where the sensor will interface with microcontrollers or control boards.

Advantages

The passive infrared design provides motion detection without emitting signals, ensuring low power consumption and minimal interference with other electronics. The 3–6 V operating range allows straightforward connection to common low-voltage control systems and battery-powered devices. The sensor's compact footprint and simple output behavior facilitate integration into a variety of modules and housings for residential and commercial applications.

Suitable for

• Intrusion and alarm systems for indoor areas
• Automatic lighting control in corridors, stairwells and rooms
• Energy-saving occupancy sensing for HVAC and smart-home automation
• Embedded electronics projects and microcontroller-based detection circuits

How to use

Connect the sensor to a compatible 3–6 V DC supply, taking care to observe correct polarity. Interface the sensor output to a microcontroller input or control relay, using pull-up or pull-down components as required by the receiving circuit. Mount the sensor in a stable position with a clear line of sight to the monitored area and away from direct heat sources or vents to reduce false triggers. Use appropriate decoupling and filtering on the supply lines if the sensor is integrated into noisy electrical environments.

Recommendations

For reliable detection, install the sensor at a height and angle that match typical human movement patterns in the monitored zone. Avoid pointing the sensor at glass, reflective surfaces or HVAC outlets. When used in battery-powered systems, verify standby current and expected battery life under the target operating conditions. For permanent installations, provide mechanical protection and appropriate mounting to prevent vibration and accidental misalignment.
