带有压力、湿度和温度传感的智能风门控制参考设计
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.
