   Description
Description 1 The SI1145 is a new sensor from SiLabs with a calibrated UV sensing element that can calculate UV Index 2 We took this outside a couple days and compared the calculated UV index with the news reported index and found it was very accurate 3 Its a digital sensor that works over I2C so just about any microcontroller can use it 4 The sensor also has visible and IR sensing elements so you can measure just about any kind of light but only the UV sensor has a calibrated output so if you need precision Lux measurement check out the TSL2561 5 If youre 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 Light Sensor Spectrum Wavelength 400nm 800nm centered on 530 3 Voltage Supply Power with DC 3 5V4 Output Type I2C address 0x60 7 bit 5 Operating Temperature 40C 85C Pinout 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
