Hydrogen sensor

Hydrogen sensor is a device that can detect the concentration of hydrogen. It is usually used in industrial, environmental and medical fields. It uses piezoelectric effect and hydrogen sensitive element to measure hydrogen concentration, so it has the characteristics of high sensitivity, fast response and good stability.

The working principle of hydrogen sensor

The hydrogen sensor works based on the piezoelectric effect. When hydrogen gas flows inside the sensor, the piezoelectric material inside the sensor is subjected to the pressure and electric field of the hydrogen gas, which creates an electrical signal. The size of this electrical signal is proportional to the concentration of hydrogen, so the concentration of hydrogen can be calculated by measuring the size of the electrical signal.

Classification of hydrogen sensors

Hydrogen sensors can be divided into various types according to different principles and uses, such as electrochemical, diffuse, semiconductor and so on. Among them, the electrochemical gas sensor is the most widely used one, which can calculate the concentration of hydrogen by measuring the electrochemical reaction of hydrogen on the electrode.
