Motion Sensor

The PIR (Passive Infrared) Motion Sensor is a reliable and easy to use motion detection solution for automation, robotics, and smart systems.

It detects motion by measuring changes in infrared radiation emitted by warm bodies (like humans). When movement is detected, the sensor outputs a digital High signal, making it perfect for triggering alarms, lights, relays, or other automated actions.

With onboard adjustable sensitivity and time delay potentiometers, you can fine:

• 🔧 Detection range.

• ⏱️ Output signal duration.

This makes it ideal for security systems, smart lighting, energy saving systems, interactive installations, and STEM projects.

Simple to integrate and widely supported in the maker ecosystem, the PIR sensor is a must have component in any electronics lab.
