System of carbon monoxide (CO) and carbon dioxide (CO2) monitoring at critical points on board a vehicle
PURPOSE
The system is designed to monitor the concentration of CO and CO2 in the driver's cab. The source of CO is the exhaust system of an internal combustion engine. Carbon monoxide enters the passenger compartment when there is a problem in the exhaust system. High gas concentrations can be fatal. CO2 sensors are relevant for monitoring leaks in cooling systems.
The system is based on selective CO and CO2 sensors with a unit for monitoring the concentration of the above gases.

DESCRIPTION
The open architecture allows you to configure systems for various conditions of use in terms of the number and type of sensors used, dimensions, processing method, information transfer, cost, etc.
The use of CO and CO2 sensors makes it possible to warn of a fire at an early stage (for example, when the insulation of a cable is damaged).
The system can be equipped with sensors for humidity, temperature, etc., if necessary.
The design of the system allows for quick and easy replacement of sensors (like replacing a light bulb), has the ability to self-diagnose, and quickly interacts with computers to process information.
