Hydrogen Energy Safety Monitoring

Due to the growing concern about environmental pollution, especially in Europe, China, Japan and South Korea, hydrogen energy vehicles are starting to gradually enter the field of vision.

gas sensor for Hydrogen Energy Safety Monitoring

The International Hydrogen Energy Commission released a survey report titled "Hydrogen, Scaling up (Hydrogen Energy Market Development Blueprint)" that clarifies the future vision of hydrogen energy, and introduced the development blueprint for the formal popularization of hydrogen energy and the transformation of energy structure.Hydrogen is considered to be an enabler of the transition to renewable energy systems and a widely used clean energy carrier.

Before 2050, through larger-scale popularization, hydrogen energy will account for about 20% of the total energy consumption, and the annual carbon dioxide emissions can be reduced by about 6 billion tons compared with the current level, able to undertake about 20% of the CO2 reduction required to keep global warming within 2°C.In terms of demand, the verification results show that by 2030, 10 million to 15 million fuel cell passenger cars and 500,000 fuel cell trucks will be supplied with hydrogen.

Today's transportation sector is almost entirely dependent on fossil fuels, with more than 20% of CO2 emissions generated by transportation. Hydrogen-powered vehicles facilitate people's lives with their high performance and fast refueling, and can also be used as fuel for electric vehicle batteries to enable widespread decarbonization of transportation. Therefore, it is well-founded that hydrogen will play an important role in reducing CO2 emissions from transportation as mentioned by the International Hydrogen Energy Commission. With more use of hydrogen, people will be more likely to meet emission reduction targets.

Why should hydrogen sensors be installed on hydrogen fuel cell vehicles?

Hydrogen is a renewable and clean energy source, but it is easy to leak and has a very wide explosion range. As long as it is mixed with air, it will explode when the proportion reaches 4% to 75%, which is a first-class explosive gas. Therefore, hydrogen fuel cell vehicles need to detect hydrogen.Use Winsen cost-effective semiconductor hydrogen sensors or high-stability electrochemical hydrogen sensors to detect leaks as soon as possible and raise an alarm to reduce the potential safety hazard of drivers.

In addition, for hydrogen fuel cell vehicles, the hydrogen sensor can not only be used to monitor the leakage of hydrogen from the gas tank and the electric pile, but also to detect the hydrogen concentration in the exhaust gas. The fuel cell vehicle can also analyze the performance and reaction degree of the electric pile in real time according to the monitored information, so as to adjust the relevant input indicators or data configuration in time to realize the safe and efficient operation of the vehicle.

How to Install and Place the Infrared Dust Sensor?

It must be installed vertically. Keep away from artificial air flow such as fans. When used in air purifiers, the front and rear of the fan cannot be installed. Optionally install it on one side of the shell, but keep vents on the shell to ensure that the external air can diffuse in.

Can the Two Voltages of Mq-7 Exist All the Time, or Do They Need to Be Powered Alternately? if It is an Alternate Power Supply, What is the Appropriate Power Supply Time?

It requires alternate power supply. Please check the information on the product manual. This sensor is powered by 1.5V and 5V alternately. The low temperature and low voltage (1.5V) state can detect CO, and the high voltage (5V) is the desorption process. The recommended 5V voltage duration is 60s, 1.5V voltage duration is 90s to alternately supply power. Since it is a desorption process at 5V, it is normal for the voltage to drop when CO is 150ppm.

Can the Catalytic Sensor Be Made into a Digital Display?

MC series catalytic products have good linearity and can be made into digital display products.
