Description
- DFRobot Gravity Alcohol Sensor (0-5ppm)
- Resolution: ≤0.01ppm (10 ppb)
- Operating Temperature: -20~50 °C
- Storage Temperature: 0~25 °C
- Power: 0.05 W (5 V)
- Supports I2C and UART outputs
The DFRobot Gravity Alcohol Sensor (0-5ppm) is an Arduino compatible alcohol sensor module from DFRobot with a 0-5 ppm measuring range, supporting I2C and UART outputs.
Aiming at fast and accurate detection of alcohol gas concentration in the air, the sensor is well applicable to the small alcohol concentration measurement in the breathalyzer, smart vehicle, and so on.
The module supports 0.01 ppm (10 ppb) resolution and 3.3 ~5.5 V wide-range voltage input and works well with mainstream controllers like Arduino, ESP32, and Raspberry Pi.
