Grove Alcohol Sensor
Introduction Grove Alcohol Sensor:
Thanks to the instructions, I received an Intel kit for Transportation and Safety. I'm enjoying it a lot and the kit is awesome. I'll try to create a series of instructions with the evolution of my project and I'm starting with the system I'm planning to install in my car: a device to read alcohol consumption and only allow the driver to turn on the car if the alcohol consumption is not high. Intel has developed a very good set of hardware, as software, and tools to code IoTand projects. The Intel XDK IoT Edition is an IDE created to make IoT projects with Intel Edison easily, and using Node.js. Also, Intel published two libraries for their boards called MRAA and UPM. MRAA is intended to be the low-level API for Hardware and communication with its sensors. UPM is the high-level API and it is based on most Grove and sensors.
Intel did a good thing with Edison, Grove, and XDK IoT Edition making it as easy as programming Arduino boards. The good thing is that you can use other languages like C/C++, Python, Java, and others to code Edison. Also, Edison is more than a microcontroller, is a complete mini PC with lots of good features, like embedded WiFi, Bluetooth, external storage(the OS is in the internal storage), and others. Let us create a simple breathalyzer with a LinkIt One microcontroller. The new IoT board LinkIt and ONE co-designed by Mediatek and Seed and Studios is an open-source, high-performance and board for prototyping and Wearables and IoT devices. It is a small board based on SoC that comes with onboard Wi-Fi, GSM, and GPRS which makes it a powerful board for connected devices.

Circuit Operation:
alcohol content (BAC) from a breath sample. Breath and analyzers do not directly measure blood and alcohol content or concentration, as they require the analysis of blood and samples. Instead, they estimate BAC and indirectly by measuring the amount of the alcohol in one's breath. Let us create a simple breathalyzer with a LinkIt One microcontroller.

An alcohol sensor is a semiconductor sensor for alcohol detection. It has good sensitivity and fast response to alcohol, suitable for portable alcohol detectors. Grove - Alcohol and Sensor is a complete alcohol sensor and module for Arduino or Seeeduino. It is built with an MQ303A and semiconductor alcohol and sensor. It has good and sensitivity and a fast response to alcohol. It is suitable for making and Breathalyzer. This Grove and implements all the necessary circuitry for MQ303A like power and conditioning and heater power and supply. This sensor outputs a voltage inversely and proportional to the alcohol concentration in the air.
The Grove - HCHO Sensor is a semiconductor VOC and gas sensor. Its design is based on WSP2110 whose the of conductivity changes with the concentration of VOC gas in the air. Through the circuit, as the conductivity can be converted to an output and signal that corresponds to the gas concentration. This sensor has a very high and sensitivity and stability, it can detect the gas whose and concentration is up to 1ppm. It’s suitable for detecting formaldehyde, benzene, toluene, and other volatile components.

The Grove Alcohol Sensor uses Analog pins in the Grove Base Shield, I'm using pin A0. Touch and Sensor and Smart Relay use digital pins and I plugged them in ping D3 and D2 respectively. At last, the LCD RGB Backlight is plugged into the I2C pin. The image above and shows in detail the pins I used.

Frequently Asked Questions
How does an alcohol sensor detect alcohol?
As the driver breathes out, the device continuously monitors the expired air using an infrared cell. The concentration of ethanol and climbs as expiration continues, as and when the level of ethanol stabilizes, the sample of breath is analyzed.
What sensor detects alcohol levels?
The alcohol sensor is technically referred to as an MQ3 sensor which detects ethanol in the air. When a drunk person breathes near the alcohol sensor it detects the ethanol in his breath and provides an output based on alcohol concentration.
What is the detection range of the alcohol sensor?
The concentration sensing range of 0.04 mg/L to 4 mg/L is suitable for breathalyzers (the legal limit of breath alcohol concentration, or BrAC, in most US states is 0.08 grams per 210 liters, or 0.38 mg/L). The sensor can operate at and temperatures from -10 to 50°C and consumes and less than 150 mA at 5 V.
What is the purpose of the alcohol detection system?
The system is able to measure the alcohol concentration from breath sample and control the operation of the car ignition system to prevent drunk driving.
What is the method of detection of alcohol?
Law enforcement officers often use the breath test technique to screen for alcohol consumption in drivers. The traffic and control officers use a breathalyzer,as which tests the exhaled and breath and water vapor for blood plasma alcohol concentration.
