Abstract: Exhaust sensors for use with residential solid fuel-burning appliances are disclosed. In one example, a sensor apparatus includes an optical sensor, a lens, and first and second light sources positioned adjacent to the optical sensor. The first light source is configured to emit a first light signal towards a target area of an exhaust gas stream. The second light source is configured to emit a second light signal towards the target area. The optical sensor is configured to detect a light signal comprising at least one of a reflected portion of the first and second light signals and a diffracted portion of the first and second light signals. The sensor apparatus also includes a processor configured to determine a concentration of smoke particles in the exhaust gas stream based on the detected light signal.

Abstract: An air intake control assembly for adjusting an air intake into a combustion chamber of a solid fuel burning appliance is provided. The air intake control assembly comprises a mounting structure having at least one air intake opening, a shutter mounted to the mounting structure and configurable between an open configuration and an at least partially closed configuration, a power supply, a motor operatively connected to the shutter and activable to modify a configuration of the shutter with respect to the at least one air intake opening, a temperature sensor electrically connected to the motor and the power supply to monitor a temperature representative of a temperature of the combustion chamber; and an electric circuit connecting the motor to the power supply and being operatively connected the temperature sensor. A solid fuel burning appliance and a method for controlling an air intake into a combustion chamber of a solid fuel burning appliance are also provided.
