A complete alcohol sensor module for Arduino.
It is built with MQ303A semiconductor alcohol sensor. It has good sensitivity and fast response to alcohol, making it suitable for building a breathalyzer. This Grove module implements all the necessary circuitry for the MQ303A, such as power conditioning and heater power supply. This sensor outputs a voltage inversely proportional to the alcohol concentration in air.
Note: The sensor value only reflects the approximated trend of gas concentration within a permissible error range, it DOES NOT represent the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which cannot be done with a single gas sensor. If your project is aimed at obtaining the gas concentration at a very precise level, then we do not recommend this gas sensor.
- Input Voltage: 5V
- Working Current: 120mA
- Detectable concentration range: 20-1000 ppm
- Grove Compatible connector
- Fast response and resumes quickly after alcohol exposure
- Long life
- Compact form factor

The time frame for order delivery is divided into two parts:
Order verification, tailoring, quality check and packaging. All orders are processed & packaged within 24-48 hours after the order is placed.
This refers to the time it takes for items to be shipped from our warehouse to the destination.
Standard Shipping: 3-5 business days
Expedited Shipping: 3 business days
Priority shipping: 1 business day
Weekend delivery is not available for all locations. An item leaves the warehouse on Friday, may not arrive until Monday even if you choose Priority Shipping.International delivery:
Only express shipping is available for international delivery. usually takes about 3-7 business days. After processing and leaving the warehouse, items usually take between 2-3 days to arrive at their destination but can take slightly longer if the destination country requires additional customs processing for the receiver.
We ship with UPS and DHL Express to other countries.
