Overview
Introduce an ultraviolet light sensor to the design with the UV Click Board™! The UV Click Board™ features an easy-to-use ML8511 IC UV sensor that is designed to warn the user of excessive ultraviolet radiation levels and outputs either analogue or digital signals that is linearly proportional to the UV intensity it detects. It also features an onboard MCP3201 ADC, which converts the signal, however, one can bypass it and get an analogue output by soldering the A/D SEL jumper in the AN position. ML8511 IC UV sensor is sensitive to UV-A (95 per cent of Ultraviolet light) and UV-B rays (the one causing sunburn).
The UV Click Board™ makes an ideal choice for making devices that notify the user of sunburn or identify the UV index as it relates to weather conditions. It also finds great use in mobile computing devices, such as a smartphone, a mobile phone, and a watch, at low power and a compact package (QFN).
The UV Click Board™ communicates with the target board through MikroBUS SPI (CS, SCK, MISO) or AN lines. It is designed to use a 3.3V power supply only.
IC/Module: ML8511 UV sensor IC
The ML8511 UV sensor is an ultraviolet light sensor that outputs an analog signal in relation to the amount of UV light it detects. Whether using the sensor indoor or outdoor, it measures ultraviolet light intensity and protects the user against excessive UV levels.
Sensitive to UV-A and UV-B rays
The sensor aboard UV Click Board™ is designed to detect 280-390nm light most effectively. This is categorized as part of the UV-A spectrum (365-315 nm) and most of the UV-B spectrum (315-280 nm). The UV-A (tanning rays) makes up to 95% of ultraviolet light were exposed to, while UV-B (burning rays) is the one causing sunburns. Be careful when experimenting with it.
On-Board ADC Converts the Signal
The MCP3201 ADC embedded in UV Click Board™ converts the signal and outputs an analog signal in relation to the amount of UV light detected. However, it is possible to bypass the on-board ADC and use the ADC on the target microcontroller instead,
