Motion Sensor ICs

Motion sensor ICs are integrated circuits designed to detect objects’ movement in nearby places during operation using single or multiple technologies. These sensor ICs are mainly integrated with PCB boards and other circuits for security purposes and send signals to the control panel to alert the operators. Furthermore, they come in various forms, each specific for a variety of applications with properly integrated circuits, such as position sensors, accelerometer sensors, inclinometer sensors, and hall effect sensors.

Technologies used within motion sensors: 

The following is a list of multiple technologies used in motion sensors.

• Ultrasonic- designed to measure the moving objects’ reflection by transmitting ultrasonic wave pulses. 
• PIR Motion sensors/Passive infrared- used to identify infrared energy or heat. 
• Area Reflective Type- designed to emit IR rays from LEDs, these sensors measure the person’s distance from an object. 
• Microwave technology is designed to measure a moving object’s reflection by sending out medium wave signals. 

Typical applications of motion sensors:

Motion sensor ICs are designed to provide a wide range of applications in various environments, such as:

• Security lighting/cameras
• Entryway lighting
• Intruder alarms
• Automated hand dryers/ Toilet flushers 
• Automatic doors/Ticket gates.
