The use of motion sensors to detect humans, animals and inanimate objects is important for security, building automation and industrial applications.
There are two primary technologies used in detecting the presence of people, pyro-electric / passive infra-red (PIR) and ultrasonic. Both work quite differently and have different benefits, depending on the application.
This webinar will provide an in-depth of analysis of these two technologies, addressing the important factors to consider when choosing a motion detection sensor.
Hosted by Martin Keenan, Technical Director at Avnet Abacus, with a 40-minute presentation from Tak Kaneko, General Manager, RF and Sensor Solutions, Murata Electronics Europe, this webinar will explore:
- Current and future applications of PIR and ultrasonic sensors
- Principles of operation
- Advantages and design considerations

PIR and ultrasonic sensors: what's the difference and how do they work
There are two primary technologies used in detecting the presence of people, pyro-electric / passive infra-red (PIR) and ultrasonic. Alessandro Mastellari takes a look at how they differ and how they work.
