Abstract
A system to reduce drafts in front of a window is described. The system includes a window covering and a motor and gearbox that adjust the window covering. The system also includes a first temperature sensor, a second temperature sensor, and a microcontroller networked to the motor and temperature sensors. The first temperature sensor is positioned above the window covering within a thermal convection zone of a window associated with the window covering, and the second temperature sensor is positioned below the window covering within the thermal convection zone. The microcontroller instructs the motor to adjust the window covering based on a temperature gradient from the first temperature sensor to the second temperature sensor.
