MICROCONTROLLER MEASURING CONVERTER FOR RESISTIVE AND CAPACITIVE SENSORS WITH TRANSMISSION OF CONVERSION RESULT OVER RADIO CHANNEL Russian patent published in 2016 - IPC G01R27/26 

FIELD: measuring equipment.

SUBSTANCE: invention relates measuring information systems, in particular to systems for measuring capacitance and resistance and can be used to measure non-electric values by resistive and capacitive sensors in wireless monitoring and control systems. Microcontroller measuring converter for resistive and capacitive sensors with transmission of the conversion result over a radio channel comprises microcontroller 1, reference resistor 2 (Ro), capacitive sensor 3 (Cx), resistive sensor 4 (Rx), reference capacitor 5 (Co), first resistor 6 and second resistor 7 of a resistive voltage divider, radio transmitter 8 with two-level amplitude manipulation. First outputs of reference resistor 2, resistive sensor 4, capacitive sensor 3 and reference capacitor 5 are connected to the first input of an analog comparator (in fig. the analog comparator is not shown) of microcontroller 1, first outputs of resistors 6 and 7 are connected to the second input of the analogue comparator of microcontroller 1. Second outputs of reference resistor 2, capacitive sensor 3, resistive sensor 4, reference capacitor 5, resistor 6 and resistor 7 are connected to the first, second, third, fourth, fifth and sixth discrete outputs of microcontroller 1 accordingly. Output of a pulse-width modulator of microcontroller 1 is connected to the modulating input of radio transmitter 8. Seventh discrete output of microcontroller 1 is connected to the power supply output of radio transmitter 8, the common output of radio transmitter 8 is connected to the common output of microcontroller 1.

EFFECT: technical result is broader functional capabilities.
