This reference design is built to enable multiple room comfort control
in connected HVAC systems. Sensing temperature, humidity, and pressure
allows independent monitoring and air-flow adjustment in each zone. This
TI Design converts a constant air volume (CAV) into a variable air
volume (VAV) system. Collected data can be transmitted wirelessly to the
smart thermostat or gateway. Onboard sensors can be employed to allow
predictive maintenance, shorten technical troubleshooting time, and
reduce overall energy consumption. Long battery life allows the smart
damper to run for many years without the need to spend time and money on
battery replacement.
