Alcohol breathalyzer circuit using 8051

Basically it has 6 pins, the cover and the body. Even though it has 6 pins, we can use only 4 of them. A little tube is placed inside the sensor.

A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch. Comes with solderable crimp pins and a mass attached to the tip. This mass increases the sensitivity to motion.

This electrode has a spherical pH sensing bulb made with high temperature glass. This design is ideal for laboratory samples, beer and other liquid samples, as well as general purpose use. Turbidity sensor, which along with a micro controller unit, takes care of turbidity measurements.

Crafted with plastic and some metal-alloy traces, turbidity sensor uses light to convey information about turbidity in water. One piece turbidity sensor. Potentiometer for maximum range setting.

Can be used to differentiate between black and white Can be used for line sensing Onboard LED indication for detection Works on 5V or 3. The sensor has an adjustable detection distance and visible light interference.

It is easy to use and is ideal for panel mounting. It is almost always used to detect the motion of a human body within the sensor's range.

The module has an on-board pyroelectric sensor, conditioning circuitry and a dome shaped Fresnel lens. Ultrasonic Sensor HC-SR04 HC-SR04 ultrasonic module can offer non-contact distance sensing function, the range of which is 2cm to cm, and the range accuracy is up to 2mm.

The module includes ultrasonic transmitter, receiver and control circuit. Raindrop Sensor Module Rain sensor can be used for all kinds of weather monitoring, and translated into output signals and AO.

As the sensor is flexed, the resistance across the sensor increases. For example you can make a robotic cocktail dispensing machine, and can use this sensors to accurately measure components like Soda, Water, etc.

Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow.

The hall-effect sensor outputs the corresponding pulse Signal. It can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.

This breakout board comes with an on-board voltage regulator and works at both 3. MF RC using advanced modulation and demodulation concept completely integrated in all types of Support A compatible transponder signals. The digital part handles ISOA framing and error detection. As a highly integrated This sensor includes a resistive-type humidity measurement component and an NTC temperature measurement component, and connects to a high-performance 8-bit microcontroller, offering excellent quality, fast response, anti-interference ability and cost-effectiveness.

It utilizes exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability. Its sensing elements is connected with 8-bit single-chip computer.Breathalyzer using The voltage output of the alcohol sensor is converted into a digital format using the ADC (IC1).

The V ref/2 pin of the ADC is held at V using the voltage divider network made of . by using Global Positioning System (GPS) and the digital maps obtained from the Geographical Information Systems (GIS) to assess threat levels for driver if approaching the curved road quickly.

Either way, after setting up a simple circuit to heat the coil in the breathalyzer, and translate the data into a signal usable for the chip, [spillsman] was able to record alcohol levels and even. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal.

MQ-6 gas sensor for propane, butane, liquefied petroleum gas sensitivity is high, natural gas and has a good sensitivity. 1. High sensitive Alcohol sensor with auto car ignition disable function 2. Alcohol Detection and Automatic Drunken Drive Avoiding System 3. automatic drunken drive prevention system - GIAP Journals.

Fig MQ-3 alcohol detection sensor The features and applications of the alcohol sensor are as follows: DESCRIPTION: This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer.
