What is the principle of oxygen deficiency latch

The Oxygen Deficiency Latch is a device used for oxygen deficiency detection, which is based on the principle of using redox reactions.

The Oxygen Deficiency Latch has an internal latch, when oxygen is lacking, oxygen will be consumed rapidly, the strontium titanate (SrTiO3) inside the latch will undergo a redox reaction, generating an electric current inside the latch, thus triggering an alarm.

The principle of the oxygen deficiency latch is simply to use the redox reaction to realize the oxygen deficiency detection by detecting the current change inside the latch. This device is widely used in industrial production, health care and other fields.
