GY-1145 SI1145 visible light infrared sensor module

I2C Board UV Visible Infrared Sensor GY1145 SI1145
SI1145 is a new SiLab sensor with UV-calibrated sensor elements that can calculate the UV index. It is a sensor that works through I2C, so as long as the microcontroller can use it. The sensor also has visible light sensor, but only the UV sensor has a calibrated output, so the measurement If you want to connect with the infrared LED to the basic LED sensor function.

Pin Out:
Vin – This is the input to the voltage regulator. Power is 3-5VDC. Reverse polarity protection.
GND – This is the ground pin for the signal and power supply, connected to the ground pin of the microcontroller

third – this is the output of the onboard controller. If 3.3VDC cleaning is required, 100mA can be drawn from this pin.
SCL – This is the I2C clock pin that is connected to your I2C microcontroller clock main pin.
SDA – I2c data pin that is connected to the master data I2C pin of its microcontroller.
