There are great needs for a low cost and low power consumption portable spirometer for the home care of respiratory diseases. A mobile monitoring system utilizing Bluetooth with low power and cost hardware equipment is proposed. A proof of concept prototype has been developed and implemented to enable transmission of a flow or volume of gas during inspiratory and expiratory process signal of a patient, which can be expanded to include other vital signs. Communication between a mobile smartphone and the spirometer is implemented using the popular personal area network standard specification Bluetooth. The flow measurement is done with commercial Platinum hot wire anemometer manufactured with MEMS technology. Owing to its smallness, it has the advantage of introducing no modification of the spatial wind distribution.
