Crowbits-UV sensor

What is the Crowbits-UV Sensor?

The UV sensor can measure ultraviolet intensity. This breakout can be very handy in creating devices that warn the user of sunburn or detect the UV index as it relates to weather conditions.

How does it work?

The UV sensor is a sensor that uses a photosensitive element to convert the ultraviolet signal into an electrical signal. When the intensity of the ultraviolet rays irradiated on the sensor is different, the sensor will generate a different conversion voltage and send it to the MCU for acquisition and conversion, which can calculate the current UV intensity.

How to use it?

Connect the UV Sensor module to the A2 and A3 ports of UNO, open the UV sensor.ino program in the UV Sensor folder, download it to the main control board, open the serial port, and observe the corresponding results.
