Abstract

In this paper, a new approach to communicate with inter-integrated circuit (I2C) enabled circuits such as sensors, over Near Field Communication (NFC) is presented and evaluated. The NFC-to-I2C interface was designed using a non-standard NFC command to control the I2C bus directly from a smartphone, which was controlling both read and write operations on the I2C bus. The NFC-to-I2C interface was reporting back the data bytes on the bus to the smartphone when the transaction was done. This system was tested in action both with write and read requests to a commercial microcontroller featuring a hardware I2C port, as well as reading a commercial I2C enabled humidity and temperature sensor. The results of the experimental tests of the system show that this approach gives an easy interface between the smartphone and external sensors, which is useful for the smartphone user.
