Description:
This kit contains the required components to build yourself an alcohol vapor detector.
This module is based on an NE555 I.C. and an MQ3 sensor.
While being a simple soldering project for beginners, this kit can be used in a variety
of small personal, educational or enterprise applications.
This alcohol sensor is suitable for detecting alcohol concentration on your breath, just
like your common breathalyzer. It has a high sensitivity and fast response time. The
MQ3 sensor provides an analog resistive output based on alcohol concentration. The
drive circuit is also very simple.
This is a D.I.Y. kit that requires soldering through-hole components on the main
double-sided printed circuit board (PCB). Users with minimal soldering tools and
intermediate skills can easily assemble this module. The assembly process should
take anywhere between 10 to 20 minutes.
