Abstract: A gas sensing leak mitigation unit for a gas system includes a gas sensing element, at least one onboard relay, and at least one microcontroller. The at least one microcontroller is configured to receive a signal from the gas sensing element and to determine if the signal from the gas sensing element is above a first predetermined threshold level. The at least one microcontroller is further configured to control the energizing and de-energizing of the onboard relays. A first onboard relay may be configured, when energized, to transmit power to a compressor of the gas system and, when de-energized, to break power to the compressor. A second onboard relay may be configured, when de-energized, to transmit power to a fan control. The gas sensing element, the at least one onboard relay and the at least one microcontroller may all be arranged within a common housing.
