Huiwen Sensor|MEMS Alcohol Sensor To Prevent Drunk Driving

The harm of drunk driving remains high and must be addressed

  Nowadays, three major elements contribute to the high occurrence of traffic accidents: drunk driving, fatigued driving, and high-speed driving. Among them, drunk driving by the drivers has the highest proportion of road accidents, and this behavior is on the rise with the continuous increase in the number of private cars, seriously affecting the stability of society. Currently, almost all countries in the world still rely on traffic police checkpoints and alcohol breathalyzers to determine whether the driver is driving under the influence of alcohol. Let's work together to promote safe driving and create a safer and more harmonious society.

▲WHO statistics on drunk driving fatalities by country

  In 2017, the World Health Organization (WHO) conducted statistics on the safety accidents caused by drink driving in various countries. Many European countries had a proportion of fatal accidents caused by drink driving that exceeded 30%, indicating that almost one-third of the drivers died from alcohol-impaired driving. When driving after drinking, drivers often experience fatigue, lack of concentration, and delayed reactions due to the stimulating effect of alcohol. Once an accident occurs, they may not have enough time to make the correct driving judgments, resulting in passive traffic accidents. In addition, the delayed coordination of eyes, hands, and feet can lead to a decrease in the ability to control the car, resulting in active accidents. Compared with normal driving, the incidence of traffic accidents caused by drink driving exceeds 16 times. Let us be responsible and drive safely.

The automotive industry is paying close attention to anti-drunk driving systems.

  With the rapid development of the automotive industry, the number of cars on the roads is increasing. Road safety has become a major concern in society, and drunk driving remains one of the most important factors causing traffic accidents. Therefore, intelligent monitoring systems for preventing drunk driving have become a key area of research. With the development of the Internet of Things technology and sensor technology, countries around the world are continuing to develop car-mounted anti-drunk driving systems. We are optimistic that with these technologies, we can reduce the losses and ensure the safety of individuals, ultimately leading to a more positive future for road traffic.

  In order to improve the effectiveness and proactivity of drunk driving control, safety technology equipment such as alcohol locks and in-car alcohol testing devices have begun to be promoted and applied in various countries. According to reports, alcohol locks have been widely used in countries such as the United States, France, and Australia. From 2021, the EU will enforce the mandatory implementation of in-car alcohol lock systems and require all new vehicles to be equipped with a connection port for alcohol testing devices by May 2022. The positive application of these technologies will undoubtedly contribute to the reduction of drunk driving incidents and promote safer driving habits.

The Application Development of Alcohol Monitoring Sensor

  In addition, various alcohol detection methods have been introduced on the market to better assist drivers in consciously testing whether they have consumed alcohol before driving. These methods aim to prevent drunk driving and promote responsible behavior on the road.

01 Mobile Phone which can prevent drunk driving

  A new type of mobile phone that can detect drunk driving was developed by Japanese mobile manufacturing technicians in 2012. The phone is equipped with a small alcohol sensor that can detect the alcohol concentration in a driver's breath if they attempt to drive drunk. This technology is highly sensitive and will help to prevent accidents caused by drunk driving. We should welcome this technological innovation and work towards creating a safer driving environment.
 

02 Breathalyzer

  In 2013, a new type of car-mounted alcohol detector named "Angel" was developed in Italy. When the concentration of alcohol in the driver's exhaled gas reaches a predetermined value, the system will sound an alarm. If the driver does not stop the vehicle, the detector will actively send a command through the car-mounted ECU, forcing the vehicle to not start or slow down to a stop. This technology provides a positive and responsible solution to prevent drunk driving accidents and promotes the safety of drivers and passengers on the road.
 

03 Alcohol Detection System

  In 2015, researchers from the U.S. National Highway Traffic Safety Administration developed a highly sensitive alcohol detection system for vehicles. Once the car detects that a driver's alcohol content is above the legal limit of 0.08%, the car will not start. This system is a positive step forward in ensuring road safety and preventing drunk driving.

  Of course, these measures to prevent drunk driving cannot do without the involvement of sensors. Alcohol sensors are mainly used to detect whether the driver has drunk alcohol and the amount of alcohol consumed. Alcohol sensors are tools used by traffic police to check whether the driver's alcohol consumption exceeds national standards in order to reduce major road traffic accidents caused by drinking and driving.

  Suzhou Huiwen Nanotechnology Co.,Ltd has developed the MEMS micro gas sensor SMD1005 based on metal oxide materials, which can be used to detect the ethanol gas content in the air. The SMD1005 alcohol sensor has the characteristics of low power consumption, high sensitivity, strong structure, MEMS process, simple driving circuit, and fast response and recovery, which can be used for detecting the ethanol vapor in the environment of consumer products such as mobile phones and computers. It is also suitable for alcohol supervision of motor vehicle drivers and other risk workers.
