Toxic Gas Detector

In the initial days of industrialization, we were not aware of the toxic outlets of those industries. As the number of industries increased, several toxic gases increased their amount in the atmosphere. These gases were made a bad impact on the workers as well as on the local people nearby the industry. To handle this hazard many rules and regulations had been made in industries whereas governments of several countries also made stringent laws to handle this scenario. In today’s article, we are going to discuss a gadget that played a role in industries to detect toxic gases. This is Toxic Gas Detector. Many of us know about it but few of them only know the inside structure of the gadget. That’s why we are here. So, without any further delay let get started.

About a Toxic gas detector:

Monitoring harmful gases in the environment can be challenging but crucial to ensure the safety of the industrial working environment. All of us know that oxygen is a life gas but you know that a large amount of oxygen became toxic. Too much oxygen or other toxic gases like Hydrogen sulfide, Chlorine, Ammonia, or Carbon monoxide, can present new dangers to the employees, equipment, and local people also. Fortunately, a Toxic gas detector is here to help us. A toxic gas detector monitors the presence of gases in a specified area and sounds an alarm or loud horn when they reach dangerous levels. The gas detectors are typically installed at the locations where there is a potential for a gas leak, and where unsafe gas levels pose an immediate danger to people.

Engineering inside this:

We have discussed this safety gadget, now we are going to discuss its internal engineering that makes this gadget useful:

  1. Detection sensor
  2. Control board
  3. Power supply
  4. Monitoring unit

Detection sensor:

As we know different types of hazardous gases could be caused for serious illnesses in humans. In every toxic gas detector detection sensor is the electronic component that detects specific gas. For example, Ammonia is detected by one sensor whereas Carbon mono-oxide is detected by another sensor. In simple terms, every sensor has its specific gas detection ability. This is what we are looking for in Toxic Gas Detectors.

To get the more sensitive and accurate sensors Metal oxide gas sensors are best. They are highly sensitive and do their job precisely. Its working technique is not new. As we know they are made of semiconductors. The electrical resistance of semiconductor material changes on the adsorption of some gases and this change in resistance can be used to detect toxic or flammable gases, which even in very low concentrations can profoundly injure the human body.
