Summer is coming, want to make a UV detector to know the UV index when you are under the sun? Grove - Sunlight Sensor is recommend here.
Grove - Sunlight Sensor is a multi-channel digital light sensor, which has the ability to detect UV-light, visible light and infrared light.
This device is based on SI1145, a new sensor from SiLabs. The Si1145 is a low-power, reflectance-based, infrared proximity, UV index and ambient light sensor with I2C digital interface and programmable-event interrupt output. This device offers excellent performance under a wide dynamic range and a variety of light sources including direct sunlight.
Grove - Sunlight Sensor include an on-bard Grove connector, which help you to connect it your Arduino easily. You can use this device for making some project which need to detect the light, such as a simple UV detector.

Hello, yes you can.
You need a software I2C because you can't connect 3 modules in one I2C bus.
About software I2C please refer to https://github.com/loovee/Arduino_SoftI2C
It can measures up to 128 klx (direct sunlight). Please refer the following datasheet https://github.com/SeeedDocument/Grove-Sunlight_Sensor/raw/master/res/Si1145-46-47.pdf
