Qwiic IR Breakout
SPX-15804 ROHS
Have you ever needed to monitor your yogurt in the community fridge because there’s a yogurt thief
loose at work? Or have you ever needed the lights to flick on when walking in a room because your
hands were full of groceries? The Qwiic IR breakout is the solution to all your people-detecting
needs.
This board utilizes Kemet Corporation’s lensless passive infrared sensor, PL-N823. It uses the
pyroelectric effect of ceramic by absorbing infrared rays emitted from the human body. This sensor
has a 60 degree viewing angle, low power consumption, and low profile which makes it ideal for
gathering visual requirements.
Though this is a lensless infrared sensor, placing the sensor behind a material like glass, acrylic, or
polyethylene may amplify the distance at which it can detect. The detecting distance varies by what
material is used, but the PL-N823 can detect up to 2 meters.
We’ve written some example code using the ADS1015 library. The qwiic IR breakout board includes
an ADC which quantifies the amplified source voltage of the IR sensor. There’s also a rudimentary
peak detection example that could notify the user when someone waves their hand across the
sensor.
We do not plan to regularly produce SparkX products so get them while they’re hot!
