Key Features of HC-SR501 PIR Sensor (Passive Infrared Sensor) + IR Proximity Sensor
- Dual-Sensor Combo: Covers both passive infrared (human motion) and active infrared (obstacle/proximity) detection in a single kit
- Adjustable Parameters: On-board potentiometers on both modules let you fine-tune sensitivity, range, and delay without extra components
- Ultra-Low Power PIR: The HC-SR501 draws under 50 uA in standby, making it ideal for battery-powered and always-on security systems
- Dual Trigger Modes: Choose single-trigger or repeatable-trigger mode on the PIR via a simple jumper setting
- LM393 Comparator on IR Module: Delivers clean, noise-free digital output for reliable short-range object detection
- Universal 3.3 V / 5 V Logic: Both sensors work seamlessly with virtually any microcontroller platform-Arduino, Raspberry Pi, ESP32, and beyond
- Plug-and-Play Wiring: Standard 3-pin (VCC, GND, OUT) headers on each module; no external pull-ups or signal conditioning required
- Compact Form Factor: Small PCB footprints fit easily inside enclosures, behind panels, or on robot chassis
- Wide PIR Field of View: 120 degrees detection cone with up to 7 m range covers entire rooms or hallways
- Visual Feedback: On-board LEDs on the IR proximity sensor indicate power and detection status for quick debugging
- Two complementary sensor technologies at one bundled price, saving you time and shipping costs
- Extensively tested and
