Elevate your electronic projects with Kunkune’s HC-SR501 Motion Sensor. Designed to detect even the slightest infrared changes, this sensor ensures accurate motion detection, making it a must-have for security systems, automation projects, and more.

HC-SR501 Motion Sensor Key Features:

  • Infrared Detection: The SR501 is adept at identifying infrared changes, interpreting them as motion and setting its output accordingly.
  • User-Centric Adjustments: The sensor’s motion interpretation can be fine-tuned based on user settings, offering flexibility in its application.
  • Wide Voltage Range: Operates efficiently within a voltage range of 4.5V to 20V, with the capability to function at lows of 3.9V.
  • Energy Efficient: With a quiescent current of just 50uA, it ensures minimal power consumption.
  • Versatile Output Levels: Offers a high output level of 3.3V and a low output level of 0V.
  • Trigger Modes: Features both L trigger (non-repeatable) and H trigger (repeatable) modes to cater to different requirements.
  • Compact Design: The circuit board, measuring 32 x 24 mm, is designed for easy integration into various projects.
  • Wide Sensing Angle: Boasts a maximum sensing angle of 110°, ensuring comprehensive coverage.
  • Optimal Sensing Distance: Can detect motion from a distance ranging between 3 to 7 meters.
