The jOY-iT SEN-MQ3-V2 is an analog alcohol gas sensor designed for integration into development boards and sensor applications. It detects alcohol vapours across a wide concentration range, making it suitable for breathalyser prototypes, air quality monitoring setups, and industrial gas detection circuits.
Analogue output signal for direct microcontroller ADC reading — no digital protocol overhead
Detection range of 100 to 10,000 ppm covers low-concentration ambient monitoring through high-concentration alcohol vapour environments
Compact sensor module fits standard breadboard and PCB mounting workflows
24-month manufacturer warranty provides long-term reliability for development and testing projects
Das zeichnet SEN-MQ3-V2 aus
Unlike digital sensors that require dedicated communication libraries, the SEN-MQ3-V2 delivers a raw analogue voltage proportional to gas concentration. This simplicity allows direct connection to any microcontroller with an ADC input, reducing firmware complexity and enabling rapid prototyping of alcohol-detection circuits.
Ideal für...
Electronics hobbyists, university lab teams, and embedded-systems developers building gas-sensing prototypes. The sensor is suited for projects where a straightforward analogue interface is preferred over complex digital protocols — from student assignments to functional breathalyser proof-of-concept designs.
Anwendung von SEN-MQ3-V2
Connect the sensor module to a microcontroller ADC pin and supply the recommended operating voltage. The analogue output voltage shifts proportionally with alcohol concentration in the sensing environment. Read the value in your firmware, apply a calibration curve if precision is required, and trigger alerts or log data based on threshold levels.
