PIR, Proximity and Motion Sensors

PIR, proximity, and motion sensors detect the presence and movement of people or objects without physical contact. They are among the most widely used sensors in automation, security, and smart home applications due to their low power consumption and ease of integration.

The range includes HC-SR501 and AM312 PIR motion sensors, capacitive proximity sensors, microwave radar motion modules for detection through walls, and ultrasonic proximity sensors for non-contact presence detection.

These sensors are used in automatic lighting systems, intruder alarm circuits, people counters, smart home occupancy detection, robot people-following builds, contactless switch inputs, STEM education security projects, and any IoT application requiring reliable detection of motion or presence.
