Description: Product Overview: HCSR501 PIR Motion Sensors, also known as Passive Infrared (PIR) sensors, are a pack of 25 individual sensors designed for detecting motion in the form of body heat and infrared radiation. Features: 1. Motion Detection: HCSR501 PIR Sensors can detect human presence or movement within a range of up to 12 feet (3.6 meters) with an angle of detection of approximately 90 degrees. 2. Low Power Consumption: These sensors have a low power consumption, making them ideal for battery-operated projects and applications where energy efficiency is crucial. 3. Adjustable Detection Sensitivity: The sensitivity level can be adjusted using external resistors to accommodate different environments or preferences. 4. Digital Output: HCSR501 PIR Motion Sensors provide a digital output (active-high), which makes them easier to integrate with microcontrollers and other electronic systems. 5. Weatherproof Design: These sensors are suitable for outdoor use as they feature a waterproof desi
