Product Descriptions

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 launched the ML8511 ultraviolet (UV) sensor IC with built-in operational amplifier. This product uses silicon on insulator (SOI) - CMOS to simulate voltage output and filter free UV sensors for the company.

OKI's UV sensor IC is suitable for digital and analog circuits due to the use of SOI-CMOS technology, which is easy to integrate with high integration. OKI stated that in the future, the company will flexibly utilize this expertise to strengthen the digital output circuit connected to microprocessors, and then form a single chip product lineup with sensing based brightness control sensors (ambient light sensors); In the future, we hope to develop decorative measuring devices that can not only provide clear and accurate UV levels, but also monitor UV hazards at any time. We also aim to promote their application in the fields of home appliances and portable devices.

ML8511 can output analog voltage proportional to the amount of UV light. Due to its ability to output voltage, it can be directly connected to the built-in MCU's A/D digital/analog converter without the need for a photoelectric conversion circuit. And it uses a small and thin surface packaging method, suitable for portable device use.
