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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
