The ML8511 breakout is an easy to use ultraviolet light sensor The MP8511 UV (ultraviolet) Sensor works by outputting 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 an 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 (OKI) to launch the built-in operational amplifier ultraviolet (UV) sensor IC – ML8511. The use of the silicon-coated product (SOI) on the insulating -CMOS, the company’s first analog voltage output, no filter UV sensor.
OKI’s UV sensor IC is easy thanks to the high degree of integration of SOI-CMOS technology, suitable for digital and analog circuits. OKI, said the company’s future will utilize this expertise to strengthen the connection of the microprocessor digital output circuit, and then with the brightness control sensor sensing type (Ambient Light Sensor) constitute a single chip lineup of merchandise; hope not only to future products done for the day at a glance the amount of UV, and ready to grasp the degree of risk decorative UV measurement equipment, and will promote the application to appliances, portable field equipment.
ML8511 UV light can be used with analog voltage output proportional to the amount. Since the output voltage can therefore be directly connected to the MCU built A / D digital/analog converter, no photoelectric converting circuit. And the use of the small, low-profile surface-mount package, suitable for use in portable devices.
