HC-SR505 PIR sensor module human detector for LED switch 2s delay time

Product Description of HC-SR505 PIR sensor module

HC-SR505 small human sensing module is an automatic control product based on infrared technology. It has high sensitivity, strong reliability, ultra-small volume, and ultra-low voltage working mode. Widely used in various types of automatic sensing electrical equipment, especially automatic control products for dry battery power supply.

Features of HC-SR505 PIR sensor module

1. Automated Detection System:

• The sensor operates on a fully automated detection system, triggering a high-level output when individuals enter its detection range. Upon exiting the range, the sensor automatically delays the high-level output, transitioning to a low output.

2. Compact and Efficient Design:

• With a super small volume, the sensor is designed for discreet and efficient installation in various settings.

3. Enhanced Triggering Mechanism:

• Employing a repeatable triggering method, the sensor maintains a high-level output if human movement is detected within the specified delay period after the initial high output. The sensor module extends the delay time with each subsequent human activity detection, using the time of the last activity as the reference point.

4. Wide Voltage Range Compatibility:

• The sensor offers compatibility with a wide range of working voltages by default, supporting operation within the DC4.5V-20V range.

5. Low Power Consumption:

• Featuring micro-power consumption with static current below 50 Micro Anno, the sensor is particularly suitable for applications requiring minimal power usage, such as those powered by dry batteries.

6. Versatile Output Signal Connectivity:

• The sensor provides a high-level output signal, enabling seamless connectivity with various circuits for enhanced functionality and integration.
