SEN0128

Gravity analogue alcohol sensor (MQ3) for Arduino t uses a MQ3 probe which can be used in a breathalyser. It has a high sensitivity to alcohol and less sensitivity to benzine. The sensitivity is able to be adjusted by the potentiometer. The output is proportional to the density of gas. Users can use analogue reading to read the data from this sensor. To ease the difficulty of using this sensor, a gravity Interface is adapted to allow plug&play. The Arduino IO expansion shield is the best match for this senor connecting to Arduino microcontrollers.

• Standard assembling structure (Times-of-5mm centre distance between two 3mm mounting holes)
• Easily recognitive interfaces of sensors ("A" for analogue and "D" for digital)
• Icons to simply illustrate sensor function
• High quality connector and potentiometer
• Immersion gold surface
• 5V power supply, analogue interface type
• Fast response and high sensitivity
• Stable and long life, simple drive circuit
• Size is 36.4 x 26.6mm (1.43" x 1.05")
