The HC-SR501 module runs on a supply voltage of DC 4.5V to 20V, letting it work directly off a 5V Arduino rail or a 9V battery without extra regulation. Idle current draw stays under 50uA, so a battery-powered sensor barely loses charge while waiting for motion.

• Detection cone under 100 degrees gives a narrower field than wide-angle 120 degree sensors, useful for pointing at a doorway rather than a whole room
• 23mm lens diameter is the default fitted to the board
• Board size of 32mm x 24mm keeps the module small enough for tight enclosures

Because it only senses infrared body heat and has no emitter, range depends on ambient temperature contrast between a person and the surrounding room.

Two onboard potentiometers control the module's behavior: one sets sensitivity, the other sets the delay before the output resets, adjustable from a few seconds up to roughly 200 seconds. A jumper selects between single-trigger mode, where detection is blocked until the delay ends, and repeatable-trigger mode, where each new movement restarts the timer.

• Retrigger jumper ships unsoldered, so enabling repeat-trigger mode requires a soldering step first
• Delay potentiometer covers roughly 0.5 seconds to 200 seconds depending on setting
• Default block time of 2.5 seconds prevents rapid re-triggering right after a detection ends

Basic wiring needs just three pins, power, ground and digital output, making it straightforward to connect to an Arduino or similar microcontroller.

This module suits DIY security add-ons, automatic lighting projects, and hobby electronics where a simple presence trigger is needed. Because it ships as five bare boards with no enclosure, wiring, or mounting hardware, it works best for builders comfortable soldering headers and designing their own housing.

• Security and automation projects such as automatic doors, lighting, or alarm triggers
• Arduino and microcontroller builds needing a low-cost motion input
• Battery-powered nodes benefit from the sub-50uA idle draw

It is not a plug-and-play consumer sensor, so buyers expecting a finished product with a case and instructions for a specific device should look elsewhere; this is aimed squarely at builders assembling their own circuit.
