AllInOne Alcohol Tester Kit This kit includes all components needed for assembly and features a compact PCB size of 60 x 36 mm, designed to fit easily into any project setup. Reliable Alcohol Vapor Detection Utilizes MQ3 sensor technology to monitor alcohol concentrations and trigger alarms, enhancing safety across various environments. Power Supply and Compatibility Operates from a DC voltage of 5V, with flexibility to be powered by multiple sources to suit different environments and setups. Automatic Device Control Builtin relay allows the system to manage other devices, such as exhaust fans, based on detected alcohol levels to strengthen safety protocols. Use scenarios and applications Industrial or workshop environments: monitor ambient alcohol vapor and automatically activate exhaust ventilation to maintain air quality and reduce exposure risk. Laboratories and solventuse areas: provide realtime alerts when alcohol vapor approaches unsafe levels, enabling staff to take prompt ventilation or procedural adjustments. Hobbyist projects and compact deployments: the small 60 x 36 mm PCB enables easy integration into portable or spaceconstrained setups, with automatic control of connected devices based on alcohol detection.
