Welcome to my review of the 10-Piece Infrared Sensor Module with Lens (HC-SR501) a versatile and high-performance sensor module that can detect human presence and movement.
With its adjustable delay time and blocking time, this sensor module is suitable for a wide range of applications, from security systems to home automation projects. Let's explore the features and benefits of this product in more detail.

When put to the test the HC-SR501 sensor module proved to be a reliable and accurate device for detecting human presence and movement. The module operates on a voltage range of DC 5V-20V, with a static power consumption of only 65 microamps. The level output is high at 3.3V and low at 0V, ensuring compatibility with a wide range of microcontrollers and other electronic devices. The delay time is adjustable from 0.3 seconds to 10 minutes, while the blocking time is set at 0.2 seconds providing precise control over the sensor's behavior.

A strong contender in the field of infrared sensor modules the HC-SR501 offers several advantages over its competitors. Its adjustable delay time and blocking time make it highly versatile, while its low power consumption ensures efficient operation even in battery-powered devices. However, some users have reported issues with the module's latch mechanism, which may require some troubleshooting or modification. Additionally the module may not be suitable for applications that require precise distance sensing or object recognition.

To sum it up the HC-SR501 is a high-quality infrared sensor module that offers excellent performance and versatility at an affordable price point. While it may have some minor drawbacks, such as the latch mechanism issue or limited sensing capabilities, these are outweighed by its many benefits and applications. If you're looking for a reliable and efficient sensor module for your next project, this is an excellent choice that should definitely be considered.
