HC-SR501 PIR Motion Sensor Module – Infrared Pyroelectric Detector for Arduino, Raspberry Pi, and DIY Electronics Projects
HC-SR501 PIR Motion Sensor Module – Infrared Pyroelectric Detector for Arduino, Raspberry Pi, and DIY Electronics Projects
The HC-SR501 Infrared PIR Motion Sensor Module is a highly sensitive and energy-efficient motion detection device that uses pyroelectric infrared technology to detect movement from humans or animals. This compact sensor is widely used in Arduino, Raspberry Pi, and other microcontroller-based projects for automation, security systems, and motion-activated devices.
Designed with adjustable sensitivity and delay time, the HC-SR501 offers excellent flexibility for a wide range of indoor applications. It detects infrared radiation emitted by moving objects, triggering a digital HIGH signal that can easily interface with microcontrollers.
Key Features:
Detection Range: 3 to 7 meters (adjustable)
Detection Angle: 100° horizontal
Power Supply Voltage: 4.5V to 20V DC
Output Type: Digital (HIGH/LOW) signal
Trigger Modes:
Repeatable trigger (H mode)
Non-repeatable trigger (L mode)
Adjustable Delay Time: 5 seconds to 300 seconds
Sensitivity Adjustment: Easily adjustable via onboard potentiometer
Low Power Consumption: Ideal for battery-powered applications
Stable Performance: Built-in voltage regulator and dual IR sensors for reliable operation

How to Request a PCB Layout / Design
- Send your complete schematic or diagram via our Facebook page.
- Our team will review your diagram carefully to understand the design scope and requirements.
- A detailed quotation will be provided based on:
-
- Design complexity
- Board size and number of layers
- Components and package types
- Special routing or manufacturing requirements
📌 Providing your diagram is essential so we can give you an accurate and fair quotation.
PCB Layout & Design Requirements
To ensure quality and accuracy, please note the following:
- All schematics must be clear, complete, and properly labeled
- Specify:
- Board dimensions (if available)
- Number of PCB layers
- Preferred components or footprints (if any)
- Hand-drawn, unclear, or incomplete schematics are not accepted
- Rush or urgent requests may incur additional charges
What’s Included in the Design Package
Each completed project includes the following deliverables:
✅ 2D PCB layout images
✅ 3D PCB render images
✅ PCB Gerber files (ready for fabrication)
✅ Bill of Materials (BOM)
✅ Component Placement List (CPL / Pick-and-Place file)
