GY-1145 DC 3V I2C Calibrated SI1145 Flora UV Index IR Visible Light Digital Sensor Module Breakout Board For Arduino

GY-1145 DC 3V I2C Calibrated SI1145 Flora UV Index IR Visible Light Digital Sensor Module Breakout Board For Arduino

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. It's 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 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 Light Sensor Spectrum: Wavelength: 400nm-800nm (centered on 530) 3. Voltage Supply: Power with DC 3-5V 4. 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

When module in the intensity of the sound environment can not reach set threshold, the OUT will output high level, when the intensity of the sound from the outside environment more than set threshold, the module OUT output low level; Small digital output board OUT can be directly to the microcontroller, through single chip microcomputer to detect the high and low level, thus to detect sound environment; Package included: 20x Microphone Sound Sensor Module
