MQ303B is a high precision digital gas sensor made by WINSEN. It uses a tin dioxide (SnO2) sensor to measure the concentration of alcohol in the air. The sensor is highly sensitive to a wide range of alcohols, from ethanol and methanol to isopropyl alcohol. It also has an internal temperature compensation function, making the measurements more accurate. The sensor can finely detect changes in the alcohol concentration, even if the changes are very small. The MQ303B has a wide range of applications including alcohol detection in home safety, breathalyzers, and industrial systems.
