- Dimensions: 40mm x 11mm
- Weight: Approximately 5 grams
Features of HC-SR505 PIR Motion Sensor:
- High Sensitivity: The HC-SR505 PIR sensor module offers high sensitivity to detect even subtle motion within its detection range.
- Adjustable Settings: Users can customize the sensor's time delay and detection range according to their specific application requirements.
- Low Power Consumption: In standby mode, it consumes minimal power (less than 60µA), making it suitable for battery-powered applications.
- Easy Integration: The module provides a 3.3V TTL-compatible output, simplifying interfacing with microcontrollers and other digital circuits.
- Compact Design: Its small size and lightweight design allow for easy integration into various projects.
- Usage Tip:
- When connecting the HC-SR505 to a microcontroller, use a voltage divider or level shifter to interface the 3.3V output with 5V logic if necessary.
- Adjust the time delay and sensitivity settings to match your project's requirements.
- Caution:
- Ensure proper power supply voltage and polarity to prevent damage to the sensor.
- Avoid exposing the sensor to direct sunlight or heat sources, as this can affect its accuracy.
- Consider mounting the sensor on a stable surface to prevent false detections caused by vibrations or movement of the sensor itself.
