Module with the MQ3 analog alcohol sensor. It enables gas detection and construction of a simple breathalyzer. The module is powered with 5 V and has an analog output (Gravity connector) with adjustable sensitivity by a potentiometer. The sensor is characterized by high sensitivity of alcohol detection with low sensitivity of gasoline detection. The Wiki page contains the manual and sample programs.
Data sheet
Arduino Uno Rev3 is a popular board with Atmel ATmega328 microcontroller from the AVR family, there are 14 I / O lines, 6 PWM channels and 6 analog inputs. The additional ATmega16U4 microcontroller realizes communication via the USB interface. Arduino A000066
Expansion board for Arduino, allows easy connection of XBee modules, has separate outputs for I2C, SPI and UART buses. The built-in 3.3V voltage stabilizer and operating mode switch make it easier to program the Arduino when the XBee module is connected to the sockets. DFRobot DFR0265
