The pre-installed filter (also sold separately if you want to convert your own camera) allows you to take an infrared photo in the “red” channel of your camera, and a visible image in the “blue” channel. These can be used to measure photosynthetic activity; you can read more about the technique here and here.
This technique was developed by contributors to the Public Lab, an open network of collaborators who develop affordable environmental science tools. Weighing less than an ounce, it’s perfect for connecting to your laptop, a Raspberry Pi, or a mobile sensing platform, and with unscrewable lenses and no infrared-block filter, it can be adapted for other uses as well.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
