Features Auto Detect: When someone enters the sensing range, sensor can detect the infrared spectrum of the human body changes, the switch automatically switches the load. Highly Sensitivity: Infrared pyroelectric sensor can detect body motion in a range of 120 degrees, making it perfect for automatic appliances. Fast Response: The delay time of this IR sensor is just 1 second, allowing you to quickly switch on or off appliances based on motion detection. Low Power Consumption: With an input voltage of DC 3.3V‑5V and maximum current resistance of 20mA, IR movement detector sensor is energy efficient. Wide Sensing Distance: PIR IR pyroelectric sensor can detect motion within 1‑2 meters, ensuring accurate and reliable detection for your needs.
