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 SI1151, a new sensor from SiLabs. The Si1151 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 on-board 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.

Applications

• Light detection

• smart irrigation system

• DIY weather station
