Description: The ML8511 breakout is an easy to use ultraviolet light sensor. 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!
OKI has introduced a built-in operational amplifier Ultraviolet (UV) sensor IC-ML8511. This product uses silicon-on-insulation (SOI)-CMOS and is the company’s first UV sensor with analog voltage output and no filter.
OKI’s UV sensor IC adopts SOI-CMOS technology, which is easy and highly integrated, and is suitable for digital and analog circuits. OKI said that the company will flexibly use this specialty in the future to strengthen the digital output circuit connected to the microprocessor, and then form a single-chip product lineup with the Ambient Light Sensor; future products hope not only It is a decorative measuring device that can understand the amount of UV in a day at a glance and can grasp the risk of UV at any time, and promote the application to the fields of home appliances and portable devices.
ML8511 can output analog voltage in proportion to the amount of UV light. Because it can output voltage, it can be directly connected to the A/D digital/analog converter of the built-in MCU, without the need for photoelectric conversion circuits. Moreover, it uses a small and thin surface packaging method, which is suitable for portable equipment purposes.
