Solar-Powered temperature sensor


Steve writes

In case you’ve not heard, there is a Green Revolution in progress. To quote a popular commercial, “The way we use energy now can’t be the way we use it in the future. It’s not conservation, or wind, or solar. It’s all of it.” I have long kept a solar-energy project in the back of my mind, so I ordered a 12v/2A solar panel power supply from a vendor. As a first step project, I figured I would power up my Arduino, use my shiny new XBee modules, and relay some sort of meaningful data back from this wireless solar-powered microprocessor.


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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.

  1. Nice, but won’t work in the dark or dusk.

    I’d be interested in how to solve the energy storage problem (particularly examples that could be copied and adapted). Some rechargeable AA batteries and some charging electronics? For low energy applications, like LED fireflies to hang in the trees in the garden, maybe a small solar panel and a largish capacitor would be enough?
