The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins(of which 14 can be used as PWM outputs) ... more16 analogue inputs, 4 UARTs(hardware serial ports) a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. The Mega 2560 is an update to the Arduino Mega, which it replaces. Revision 3 of the board has the following new features: 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near the RESET pin. The IOREF that allows the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that uses the AVR, which operates with 5V and with the Arduino Due that operates with 3.3V. The second one is not a connected pin, that is reserved for future purposes. Stronger RESET circuit. Atmega 16U2 replace the 8U2. Microcontroller: ATmega2560 Operating Voltage: 5V Input Voltage(recommended) 7-12V Input Voltage(limits) 6-20V Digital I/O Pins: 54(of which 15 provide PWM output) Analogue Input Pins: 16 DC Current per I/O Pin: 40 mA DC Current for 3.3V Pin: 50 mA Flash Memory: 256 KB of which 8 KB used by bootloader SRAM: 8 KB EEPROM: 4 KB Clock Speed: 16MHz

The MP8511 UV(ultraviolet) Sensor works by outputing an analog signal in relation to the amount of UV light that’s detected. 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. This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB(burning rays) spectrum and most of the UVA(tanning rays) spectrum. It outputs a analog voltage that is linearly related to the measured UV intensity(mW/cm2) If your microcontroller can do an analog to digital signal conversion then you can detect the level of UV!
