5pcs HCSR501 PIR Motion Sensor Module for Arduino Raspberry Pi, Adjustable IR Detector with Smart Motion Detection

Product: HCSR501 Adjust IR Pyroelectric Infrared PIR Motion Sensor Detector Module Model number: FZ0057 Pack options: 5 pieces or 10 pieces Material: Polymer Type: Biosensor Output: Switching Transducer Use: Ray Sensor concern chemicals: None : Yes Description This listing contains HCSR501 adjustable IR pyroelectric PIR motion sensor modules, model FZ0057, supplied in packs of 5 or 10 pieces. Each module provides a switching transducer output that changes state when motion is detected, enabling clear on off control for a wide range of low voltage control circuits and automation projects. Key benefits Reliable motion detection: The pyroelectric infrared sensor responds to moving heat sources and provides a switching output suitable for triggering alarms, lights, or control inputs. Adjustable operation: Built in adjustment lets you tune sensitivity and trigger timing to match the installation and reduce false triggers. Easy integration: Standard switching output and polymer construction make the modules simple to incorporate into custom electronics, control panels, and prototype boards. Clean materials: No concern chemicals are present in the modules, supporting routine handling and installation. options: Modules can be supplied with as required for specific projects or OEM needs. Important attributes Function: Infrared pyroelectric passive infrared motion detection with switching transducer output. Compatibility: Works with standard low voltage control circuits, microcontroller inputs, alarm and lighting control systems, and other switching inputs. Material: Polymer construction for a balance of durability and lightweight handling. Performance: Adjustable sensitivity and timing support tailoring detection behavior to the application without additional circuits. Packaging: Available in packs of 5 or 10 modules to suit small projects or bulk installations. Practical applications Motion activated lighting: Use the module to switch indoor or corridor lighting on when movement is detected and off after a set delay, helping automate lighting control. Basic security and alarm systems: Connect the switching output to alarm inputs or monitoring circuits to detect human movement and trigger alerts. Robotics and automation: Integrate into robots or automated devices for simple presence detection, corridor traffic counting, or wake on motion behavior. Installation tips Connect the switching output to the control input or relay suited to your system voltage and logic levels. Adjust sensitivity and timing to reduce false triggers from pets or air movement and to match the required response delay. Test the module in the final installation environment to confirm coverage and adjust settings as needed.
