VEML6070 UV Index Sensor Breakout
Discontinued; replaced by the Adafruit LTR390 UV Light Sensor (STEMMA QT / Qwiic).
Pinout
- Vin
Power input for the VEML6070 breakout; Adafruit Learn states the sensor chip uses 3 to 5 VDC and the board should be powered at the microcontroller logic level.
Type · powerVoltage · 3 to 5 VDC - GND
Common ground for power and logic, as stated by Adafruit Learn.
Type · groundVoltage · 0V - SCL
I2C clock line; Adafruit Learn states this pin connects to the microcontroller I2C clock and can be used with 3V or 5V logic with a 10K pullup.
Type · i2cVoltage · 3V or 5V logic - SDA
I2C data line; Adafruit Learn states this pin connects to the microcontroller I2C data line and can be used with 3V or 5V logic with a 10K pullup.
Type · i2cVoltage · 3V or 5V logic - ACK
Interrupt/alert output for high or low UV signal warning; Adafruit Learn states the logic level follows Vin.
