Have you ever needed to monitor your yogurt in the community fridge because there\u2019s 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.<\/p>\n\n
This board utilizes Kemet Corporation\u2019s 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.<\/p>\n\n
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 Kemet claims the PL-N823 can detect up to 2 meters with a matching lens. This product does not include a lens so expect ranges closer to 10cm out-of-the-box.<\/p>\n\n
We\u2019ve 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\u2019s also a rudimentary peak detection example that could notify the user when someone waves their hand across the sensor.<\/p>\n\n
We do not plan to regularly produce SparkX products so get them while they\u2019re hot!<\/p>\n\n
