This form of electromagnetic radiation has shorter wavelengths than visible radiation. The UV Sensor is based on the sensor GUVA-S12D which has a wide spectral range of 200nm-400nm. The module outputs electrical signal which varies with the UV intensity, which gives your suggestion if it is a good idea to beach today.

> **[Sensoren](https://www.tinytronics.nl/shop/nl/sensoren)** > > Sensoren zijn nodig om specifieke dingen te kunnen detecteren. A lot of different sensors for measuring distance, light, gas, temperature, humidity, PIR, flame sensors and much more. The [flame sensor](http://www.tinytronics.nl/shop/Sensoren/Licht-Infrarood/Vuur(Infrarood)-Sensor-Module) is nice. I use these in a laser cutter and as soon as a flame is detected the laser and fan are stopped and an alarm will sound. Also, the laser is moved back to homing position to prevent damage to lenses or mirrors. Could be a nice sensor to check for fire in hot & dry periods. Too bad the website is only available in Dutch 😢 ---
