This infrared sensor is a small device (about 3.2cm x 2.4cm x 1.8cm) that detects infrared radiation. It comes with a built-in circuit board for controlling its functions.
- Adjustable settings:Â You can fine-tune how sensitive the sensor is to movement and for how long it stays activated after detecting something.
- Wide operating range:Â The sensor works with a power supply between 4.5 and 20 volts and uses very little power (less than 60 microamps).
- Digital output:Â The sensor outputs a simple high or low signal (3.3 volts) to indicate whether it detects something.
- Customizable detection zone:Â You can adjust the distance (up to 7 meters) and angle (up to 140 degrees) at which the sensor picks up movement.
- Flexible timing:Â You can set a delay time between 5 and 200 seconds to control how long the sensor stays active after it detects something. There’s also a fixed 2.5-second period where the sensor won’t detect anything after activation.
- Selectable trigger mode:Â You can choose between a trigger mode that only activates the sensor once per detection or a mode that keeps it activated as long as it keeps detecting movement.
- Durable operation:Â The sensor can function in temperatures ranging from -20 to +80 degrees Celsius.
