Description

Summer is coming, want to make a UV detector to know the UV index when you are under the sun? Grove ?? Sunlight Sensor is recommended 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 includes an onboard Grove connector, which helps you to connect it to your Arduino easily. You can use this device for making some projects which need to detect the light, such as a simple UV detector for your Raspberry Pi weather station, or a smart irrigation system using Arduino if you need to monitor the visible spectrum.
