HC-SR505 Mini Infrared PIR Motion Sensor
The HC-SR505 Mini Infrared PIR Motion Sensor Module utilizes infrared technology to automatically control products with high sensitivity, reliability, a compact size, and low voltage operation.
This technology is commonly employed in a variety of electrical devices that feature automatic sensors, particularly those that are powered by batteries.
The following are some examples of applications:
- Mobile applications
- Web applications
- Desktop applications
- Induction lamps use electricity to create light that is directed into a specific area for illumination purposes.
- Toys with built-in body sensors.
- Protective gear.
- Automation and control in an industrial setting.
- The automatic detection of electrical devices.
- Automated control powered by a battery.
Highlighted characteristics included:
- Energy efficiency is a key feature of this product.
- The output level varies from high (3.3V) to low (0V).
- The default setting for this trigger is repeatable.
- The automatic induction feature triggers a high output when entering the sensing range and automatically turns off after leaving, resulting in a low output. Additionally, it boasts an ultra-compact size.
- HC-SR505 Mini Infrared PIR Motion Sensor will repeatedly trigger when it senses human activity within its range. This will result in a high output, which will remain until the individual leaves the area, followed by a variable delay before returning to a low output. The sensor module automatically detects and extends the delay period based on each instance of human movement, with the previous event marking the beginning of the delay time.
- The default operating voltage for a wide range is DC4.5V-20V.
- Micropower, with a quiescent current of less than 50 microamps, is particularly suitable for battery-operated automatic control devices. Its high signal output makes it highly compatible with various circuits and easy to connect.
