Product description: VEML7700 light intensity sensor - I2C - STEMMA QT / Qwiic - Adafruit 4162
VEML7700 light sensor module from Adafruit, allowing measurement of light intensity in the range from 0 lux to 120 klux . It offers up to 16-bit resolution , which translates into measurements with an accuracy of up to 0.0036 lx/ct. It allows you to change the gain, so you can make more precise measurements in a dark environment. It also has the option of removing noise from 100 Hz and 120 Hz tubes. Communication with the microcontroller takes place via the I2C interface, including the built-in STEMMA QT connector. The board also includes a voltage regulator and a logic level converter , allowing work with devices powered with voltages from 3.3 V to 5 V. The green LED informs us about the power supply status.
VEML7700 light intensity sensor - I2C - STEMMA QT / Qwiic - Adafruit 4162.
The module is compatible with Arduino and Raspberry Pi !
The manufacturer has prepared a detailed user guide and libraries for Arduino and Raspberry Pi that will make working with the sensor easier.
Communication with the microcontroller takes place via the I2C interface.Connecting the VEML7700 sensor
To facilitate the use of the sensor, the manufacturer made it possible to easily connect the module to the microcontroller via the STEMMA QT / Qwiic connector. It uses the popular I2C interface and uses supply voltages of 3.3 V and 5 V. Alternatively, it is possible to solder the goldpin connectors included in the set to the appropriate pins. The module outputs include:
- Vin - supply voltage input in the range from 3.3 V to 5 V
- 3Vo - voltage output from the built-in regulator, efficiency 100 mA
- GND - common ground of the system
- SCL - clock pin of the I2C interface
- SDA - I2C data pin
