Description

The HC-SR505 is a mini motion sensor module often used in various electronics and DIY projects. It is commonly referred to as a “mini PIR (Passive Infrared) sensor” due to its function of detecting motion by sensing changes in infrared radiation. Here are the key features and details of the HC-SR505 Mini Motion Sensor:

1. **Motion Detection:** The HC-SR505 is designed to detect motion within its field of view. It does so by sensing changes in heat and movement using passive infrared technology. When motion is detected, it can trigger an output signal.

2. **Miniature Size:** The sensor module is compact and has a small form factor, making it suitable for applications where space is limited or where a discreet sensor is preferred.

3. **Voltage Input:** It typically operates on a supply voltage in the range of 4.5V to 20V DC, making it compatible with a variety of power sources, including batteries and power adapters.

4. **Digital Output:** The sensor provides a digital output signal, which goes high (usually to 3.3V or 5V) when motion is detected and low when there is no motion. This output can be used to trigger other electronic components, such as microcontrollers or relays.

5. **Sensitivity Adjustment:** Some HC-SR505 modules have a potentiometer for adjusting the sensitivity of the motion detection. This allows you to fine-tune the sensor to match your specific requirements.

6. **Time Delay:** The module often includes a time delay adjustment, which allows you to set the amount of time the output remains high after motion is detected. This can help prevent false triggers or provide a specific delay for your application.

7. **Applications:** The HC-SR505 Mini Motion Sensor is used in various applications, including security systems, lighting control, automatic door opening, and other projects that require motion detection.

8. **Operating Mode:** Some modules have a single trigger mode, which means that they will trigger the output once when motion is detected and reset only after motion stops. Others may have a repeatable trigger mode, which allows them to trigger continuously as long as motion is present.

9. **Lens and Field of View:** The sensor module comes with a lens that determines its field of view and sensitivity range. Different lens options are available for different applications.

10. **Quiet and Low-Power:** HC-SR505 sensors are known for their low power consumption and relatively silent operation, making them suitable for battery-powered and noise-sensitive applications.

The HC-SR505 Mini Motion Sensor is a versatile and cost-effective component that is widely used in electronics projects for motion detection and automation. It is relatively easy to interface with microcontrollers like Arduino or Raspberry Pi, allowing you to create custom solutions for various applications, from smart lighting to security systems.
