Description

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.

Features
  • SimpleLink™ software platform
  • Integrated Bluetooth® low energy radio and MCU for smaller form factor
  • Configurable advertisement interval up to 4 seconds
  • Ultra-low-power consumption
    • Total average current of 30.56 μA (five louver adjustment events per day)
    • 3.7-μA standby current
    • 61-μA/MHz ARM® Cortex®-M3
    • DC-DC converter uses 28 μA of average power (500-ms advertisement interval)
  • Operates on 4 AA batteries
  • Motor driver has integrated FETs and current sense comparator, enabling easy design, and small solution size with minimal discretes
