What is an alcohol sensor?

The alcohol sensor is technically referred to as a MQ3 sensor which detects ethanol in the air. When a drunk person breathes near the alcohol sensor it detects the ethanol in his breathe and provides an output based on alcohol concentration. If there is more alcohol concentration more LED’s would lit.

What is the range of alcohol sensor?

An alcohol sensor detects the attentiveness of alcohol gas in the air and an analog voltage is an output reading. The sensor can activate at temperatures ranging from -10 to 50° C with a power supply is less than 150 Ma to 5V. The sensing range is from 0.04 mg/L to 4 mg/L, which is suitable for breathalyzers.

How do you use an alcohol sensor?

Let’s hook the MQ3 alcohol sensor up to the Arduino. Start by connecting VCC pin to the 5V pin on the Arduino and connect GND pin to the Ground pin on the Arduino. Finally, connect AO output pin on the module to Analog pin#0 on the Arduino.

What is a passive alcohol sensor?

The passive alcohol sensor (PAS) is a device developed to assist police in identifying drinking drivers. The PAS draws in mixed expired and environmental air from 6 inches in front of the subject’s face and passes it into a fuel cell sensor that can detect very small amounts of alcohol.

Is alcohol sensor analog or digital?

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. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor.

What does the touch sensor do?

A touch sensor is an electronic sensor used in detecting and recording physical touch. Also known as tactile sensors, it’s a small, simple, low-cost sensor made to replace old mechanical switches we seen in the past.

What is a smoke gas and alcohol sensor?

When there is a fire a lot of gas particles are produced. The sensor detects these and turns the electricity supply on. It can be used to detect the presence of carbon monoxide gas (CO). … The sensor detects the gas and the alarm is set off.

How do you test an alcohol sensor?

Disclaimer: You don’t have to drink alcohol in order to test this sensor. Mouthwash, such as Listerine, contains alcohol. If you gargle mouthwash for a few seconds and then breathe into the sensor, the readings should jump and register. This is all that’s needed to test.

What is Colour sensor?

A colour sensor is a type of “photoelectric sensor” which emits light from a transmitter, and then detects the light reflected back from the detection object with a receiver.

What is gas sensing?

Gas sensors (also known as gas detectors) are electronic devices that detect and identify different types of gasses. They are commonly used to detect toxic or explosive gasses and measure gas concentration. … Most home based smoke detection systems are oxide based sensors.
