The ARCELI GY-1145 is a cutting-edge digital sensor module designed for Arduino enthusiasts, offering precise measurements of UV, IR, and visible light through I2C connectivity. Its calibrated output ensures accuracy, making it ideal for both casual and advanced projects.

## Description

Description:1. The SI1145 is a sensor from SiLabs with a calibrated sensing element that can calculate Index.2. We took this outside a couple days and compared the index with the news-reported index and found it was very accurate!3. It's a digital sensor that works over I2C so about any microcontroller can use it.4. The sensor also has visible and IR sensing elements so you can measure about any kind of - but the sensor has a calibrated output so if you need precision measurement check out the TSL2561.5. If you're feeling really advanced, you can connect up an IR LED to the LED pin and use the basic proximity sensor capability as well.SI1145 details:1. IR Sensor Spectrum: Wavelength: 550nm-1000nm (centered on 800)2. Visible Sensor Spectrum: Wavelength: 400nm-800nm (centered on 530)3. Voltage Supply: Power with 3-5V4. Output Type: I2C address 0x60 (7-bit)5. Operating Temperature: -40°C ~ 85°CPinout:Vin - this is the input to the voltage regulator. Power with 3-5VDC. Has reverse-polarity protection.GND - this is the signal and power ground pin, connect to your microcontroller ground pin.3vo - this is the output from the onboard regulator. If you need a clean 3.3VDC, you can draw up to 100mA from this pin.SCL - this is the i2c clock pin, connect to your microcontroller I2C clock master pin.SDA - this is the i2c data pin, connect to your microcontroller I2C data master pin.Package included:1 x GY-1145 I2C sensor module
