Microelectronics probe for automatic, simultaneous control and monitoring of several chemical physical parameters of liquid substances, and their transmission to remote stations

This invention relates to electronic devices, which are capable to continuously measure, through a planned sampling, some chemical-physical parameters of liquid substances - in particular, water and water solutions - and record and transmit such data without any human intervention. These parameters include (but are not limited to): temperature, relative hydrostatic pressure as level indicator, ionic conductivity, pH and redox potential, concentration of specific ions (Cl, F, O, NH4, NO3, metal ions, etc.). This invention is characterised in the fact that all the sensing elements are implemented on a single substrate and all the electronics performing such functions is hosted in the same housing of the sensor. Most of the unique probe functions are implemented by the hardware and software combination, and the probe itself can be described as an integrated system. This results in a very compact device with low power consumption, easy installation and maintenance and a lower overall operating cost.
