PIR motion detector Renkforce 1362990 360° passive infrared sensor

PIR motion detector Renkforce 1362990 360° passive infrared sensor is a compact indoor presence sensor that monitors changes in infrared radiation to detect human movement. Designed for all-round coverage, the device senses motion across a full 360° field, making it suitable for basic security monitoring and automated control of lighting and energy systems. The unit is intended for fixed indoor installation where unobstructed detection of people entering or occupying a space is required.

Advantages

The passive infrared design detects body heat variations without emitting signals, offering low power operation and reliable response to human movement. Its 360° detection pattern reduces blind spots in central mounting positions and simplifies placement decisions. The compact housing allows installation on ceilings or other interior surfaces with minimal visual impact. Because the detector reacts to changes in infrared radiation, it provides fast switching for automation tasks such as lights or timers and can act as a basic input for alarm or energy-management systems.

Suitable for

• Room occupancy detection for automated lighting
• Basic intruder or presence detection in corridors and common areas
• Energy-saving control in offices, storage rooms, and utility spaces
• Trigger input for alarms, timers, or building automation systems

Key specifications

• Detection type: passive infrared (PIR)
• Coverage: 360° horizontal detection pattern
• Intended mounting: indoor, ceiling or wall placement for all‑around sensing
• Sensing target: human movement based on infrared radiation changes
• Typical applications: lighting control, presence sensing, basic security input
• Physical characteristics: compact form factor suitable for unobtrusive installation

How to use

Mount the PIR motion detector in a central indoor location such as a ceiling or high wall to achieve unobstructed 360° coverage. Avoid placing the sensor near direct heat sources, air vents, or behind large obstacles that block line of sight. Connect the detector according to the installer instructions or the interface requirements of the target control system, ensuring correct wiring and power supply methods for the environment. After installation, perform a walk test to verify detection range and adjust mounting position if necessary to capture the intended coverage area.

Recommendations

For reliable operation, install the sensor at the manufacturer’s recommended height and away from direct sunlight, heating elements, or strong drafts that could cause false triggers. Use the detector as part of a layered approach to automation or security — combine with lighting controllers, timers, or alarm systems to achieve the desired functionality and energy savings.
