ABSTRACT
This chapter looks at the potency of smartphones that can be applied as sensors to remotely gather environmental data. The challenge of power consumption still remains from the first mobile phones, in the 1980s, which were not light, small, and smart. The goal of the first version of the Bluetooth sensor was to demonstrate the feasibility of the architecture and to provide a device that is easy to interface to; this way showed how to have a simple data stream to develop the “client side” application more easily. The first version consumed too much power. Consequently, the second version was designed to keep the power as low as possible. Two experiments were carried out; the first to test the reliability of the sensors and the second to measure their power consumption. A laboratory test using a climate chamber was applied to verify the performance of the system. The climate chamber changed the environmental conditions.
