The Gas and Smoke Detection Application, "AEL-AD30", is designed to study the operation of a gas leak detection and fire prevention system. This application includes two types of sensors. On one hand, there is a gas detector capable to detect explosive and toxic gases, such as natural gas, propane, butane, etc.

It can also detect smoke from combustion, so it is a very complete sensor. On the other hand, there is an optic smoke detector, capable to detect visible gases, although it must not be installed close to water heaters to avoid a false positive result. The application also includes a solenoid valve to close the gas circuit in case of leakage. The student can simulate with all of these devices some emergency situations to understand the operation of the main gas detection systems in the market.
