Here’s a lovely little project useful for monitoring your sun exposure. It even monitors humidity, pressure, and temperature. Well done for using the stunning and low power Sharp memory LCD. And with the simple clean enclosure, it looks a lot better than some other devices on the market. You can find the UV-badge on Hackaday.io.
[This UV sensor board is] a professional one-off, capable of displaying the UV index, temperature, humidity, and pressure in one tiny little enclosure. The UV badge is designed to be used outdoors… The device is powered by a single coin cell battery that should give months of run time.
