Keyes Alcohol Sensor (Red)
—A Keyes alcohol sensor module on a red PCB that responds to alcohol vapour in the air, giving an analogue reading that rises with concentration.
Specifications
- Gas-sensing element responsive to alcohol vapour
- Analogue output proportional to concentration
- Digital threshold output on most revisions
- Supply 5 V DC
- Needs a warm-up period before readings settle
What you can build with the Keyes Alcohol Sensor (Red)
- Breath and vapour detection experiments
- Air-quality demonstrations
- Science-fair and classroom projects
- Fermentation monitoring
Compatibility
Arduino analogue inputs; Raspberry Pi and ESP32 via an ADC. Not a calibrated or legal-standard breathalyser.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
