Abstract:
A method for an inductive communication and localization system for wireless sensors in internally illuminated photobioreactors is presented here. The communication is implemented through an on-off switched hartley-oscillator where its inductance is used as transmitting coil for the wireless sensor data. As modulation technique, the on-off keying is used. The magnetic field of the transmitting coil is sensed from outside the reactor with special designed receivers in order to evaluate the magnetic field components of the transmitting coil in all three spatial directions at one position. This enables the localization of the transmitting coil and thus the localization of the wireless sensor. A prototype has been implemented and test measurements performed with a two receiver setup. Additionally simulations were performed in order to see the accuracy improvement of the localization by using more receivers.
