Bluetooth Enabled Mobile Application for HVAC Device Access
Subscribe/Renew Journal
Most of the home appliance companies primarily develop components for Heating Ventilation and Air-Conditioning (HVAC) Systems like Thermostats, Furnace Controls, etc. These components communicate with each other either via relay signaling or using communication protocols like the CT-485. Home appliances such as security and climate control systems have become more advanced with the recent improvements in microcontrollers and wireless technologies such as Bluetooth. And most of the companies have taken advantage of this in recent years with the development of Bluetooth enabled thermostat.
This work addresses the problem of automatic control of HVAC devices and issues related to development of suitable software for controlling the heating processes using wireless and mobile technologies. For that purpose this work make use of non traditional method of control viz use of Mobile Phone. This work concerns the mobile phone based application that could communicate with Bluetooth enabled Thermostat and it could be used to fetch data from the device and also set parameters or send control signal in the other direction.
