Product description: Gravity - alcohol sensor 0-5ppm - I2C / UART - DFRobot SEN0376
Sensormanufactured byDFRobotforaccurate measurementofalcoholconcentration in the air. It is used during low alcohol concentration measurement, inbreathalyzers, smart vehicles and projects containinggasdetection mission. Measured measuring range isfrom 0 ppm to 5 ppm. The module has aGravitycompatible connector and uses two interfaces: anI2Cbus and aUARTto communicate with the main module. It is compatible with microcontrollers such as Arduino.

Contents of the kit
- Alcohol sensor
- Connection cable with Grove connector
- Spacer sleeve M3 x 10 mm - 4 pcs.
- Mounting screws M5 x 5 mm - 8 pcs.
- When the module is first commissioned, it is recommended that the preheating should last for approximately 24 to 48 hours.
- The alcohol concentration during preheating will stabilize after 3 minutes, so ignore the data generated during this time.
