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. **Features:** Digital light sensor Wide spectrum detection range Programmable configuration 3.3/5V Supply Detect sunlight directly Grove compatible I2C Interface(7-bit) **Specification:** Operating Voltage: 3.0-5.5V Working current: 3.5mA Wave length: 280-950nm Operating Temperature: -45-85oC **DOCUMENTS** Please visit our [wiki][4] page for more info about this product.
