Sensitivity range from 365 to 280 nm (UV-A and UV-B rays) Choose between digital and analog output Can be used both indoors and outdoors Designed to use 3.3V power supply
With UV click, you can design devices that warn you of excessive ultraviolet radiation levels. UV click carries an ML8511 UV sensor IC that is sensitive to UV-A (365-315nm) and UV-B (315-280nm) rays. The board can produce a digital or analog output signal that is linearly proportional to the UV intensity it detects (UV intensity is measured in mW/cmē).
Output is digital by default, communicating via mikroBUS SPI (CS, SCK, MISO) lines. You can bypass the on-board MCP3201 ADC if you want to use the ADC on your host microcontroller instead just solder the A/D Select jumper (zero-Ohm resistor) to the AN position and the board will produce analog output on the mikroBUS AN line.
The sensor can be enabled or disabled by the host MCU through the RST (EN) pin.
Note: UV click uses a 3.3V power supply only. Also, be careful not to press or rub the sensitive surface of the ML8511 sensor IC.
The sensor responds to UV-A and UV-B rays. UV-A makes up to 95 percent of Ultraviolet light we're exposed to, but UV-B is the one causing sunburns. Be careful when experimenting with it.
mikroBUS Click Boards Overview Click boards come with header pins that you must solder yourself. After that, they just plug directly into a mikroBUS socket. mikroBUS is a specially designed plug-and-play pinout standard. Newer (v7) development systems manufactured by mikroElektronika, which we carry, have mikroBUS sockets already built in.
You also can connect Click boards to many other popular platforms via these adapters:
- PC Click USB Adapter (MIKROE-1433)
- Arduino Arduino UNO click shield (MIKROE-1581)
- Raspberry Pi Pi click shield (MIKROE-1512)
- BeagleBone Black BeagleBone click shield (MIKROE-1596)
- STM32F3 Discovery STM32F3 Discovery Shield (MIKROE-1447)
- STM32F4 Discovery STM32F4 Discovery Shield (MIKROE-1481)
- Stellaris LM4F120 LaunchPad / Tiva TM4C123G LaunchPad Click BOOSTER PACK (MIKROE-1363)
In addition, it is royalty-free to add mikroBUS to your own designs. Visit the mikroBUS Category to see the full line of Click boards.
