fmarzocca @ instructables.com build a portable UV index meter with Arduino. He writes: Being unable to expose myself to the sun due to a dermatological problem, I used the time I would have spent on the beach to build an ultraviolet rays meter. UltraV. It is built on an Arduino Nano rev3, with an UV […]
Arduino UV Meter using the UV30A Ultraviolet Sensor
https://www.electronics-lab.com/arduino-uv-meter-using-uv30a-ultraviolet-sensor/
Ultraviolet rays, also known as UV for short are rays emitted by sun. Due to the depletion of the ozone layer, these rays tend to get to extreme levels that could lead to sunburns etc for those under it, that’s why daily and hourly forecast of the UV index is always available to help people […]
World´s Smallest Wearable Made to Help Prevent Skin Cancer
https://www.electronics-lab.com/worlds-smallest-wearable-made-help-prevent-skin-cancer/
Wearables are devices that incorporate and interact with different parts of our bodies and perform a specific task. The tasks can be to improve our health (count steps, heart rate etc.) or to make our life easier (GPS, smartwatches etc.). Technology industry has dominated the wearable market since its easier for a technology company to […]
