Micronas mySENS gas sensing technology

Click2Contact

Micronas has released a current measurement transducer and a gas sensor.

The mySENS gas sensing technology represents a versatile integrated sensor based on a CCFET sensor (capacitive coupled field effect transistor).

This technology aims at detecting concentration changes of selected gases in ambient environments in a broad variety of different applications.

Its fabrication process is embedded into CMOS manufacturing so that the sensor can be integrated together with control and evaluation electronics into one single chip.

The CUR 3105 is a current transducer based on the Hall effect and can be used for precise current measurements. The output voltage is proportional to the measured current and the supply voltage (ratiometric analog output). Major characteristics, such as magnetic field range, sensitivity, output quiescent voltage and output voltage range, are programmable and are stored in the internal EEPROM.

It is possible to program different transducers which are in parallel to the same supply voltage individually. The transducer operates with typically a 5 V supply in the wide junction temperature range of -40 to 170 °C.
