The challenge

The world is constantly moving and with the proximity sensor we can detect this motion. What makes this sensor special is its ability to differentiate motion based on variations in temperature. Some common applications are home automation, like smart thermostats, robot vacuums, home appliances, etc. In a nutshell, any application where you would want to sense human motion would be a great place to incorporate the proximity sensor. How would you use the proximity sensor? Get your creative juices flowing and share your best ideas. Build your best application idea and submit to win!

Hardware Description

KEMET’s Pyroelectric Infrared Sensors use the pyroelectric effect of ceramic by absorbing infrared rays emitted from the human body. This detects the natural infrared signature produced by humans. Also, it can detect infrared rays without using lenses.

Due to the absence of a lens, KEMET’s Pyro Sensor is low profile, as it does not protrude, which makes it ideal forgathering visual requirements. With KEMET’s proprietary piezoelectric ceramic material and element structure of the Pyroelectric Infrared Sensor, humans can be detected through resin. This allows more freedom in the design of the outer appearance of the end product.

By adding a KEMET proprietary lens the detection distance can be further improved. Three different color lenses also enable some design flexibility. The sensors now packaged in our module solution are even easier to install and the driving being already included in the package, makes it really just “plug and sense."
