MICROCONTROLLER DEVICE TO MEASURE CAPACITANCE AND RESISTANCE AND TRANSFER OF MEASUREMENT RESULT ALONG RADIO CHANNEL Russian patent published in 2015 - IPC G01R27/00 

Abstract RU 2550595 C1

FIELD: measurement equipment.

SUBSTANCE: microcontroller device for measurement of capacitance and resistance and transfer of the measurement result along a radio channel comprises a microcontroller (MC) 1, a sample resistor 2 (Ro), a capacitance sensor 3 (Cx), for instance, of air moisture, a resistor 4 (measured resistance Rx), for instance, a thermistor, a capacitor of sample capacitance 5 (Co), a resistive divider, comprising resistors 6 and 7, an outlet 8 of binary code transfer. Resistors 2 and 4 by the first outlets are connected to a non-inverting inlet of an analogue comparator of an MC 1 and the first plates of the capacitance sensor 3 and the capacitor 5 of sample capacitance, the first outlets of resistors 6 and 7 of the voltage divider are connected to the inverting inlet of the analogue comparator of the MC 1, the second outlets of resistors 2 and 4 are connected, accordingly, to the first and second outlets of the MC 1, the second plates of the capacitance sensor 3 and the capacitor 5 of the sample capacitance are connected, accordingly, to the third and fourth outlets of the MC 1, the second outlets of resistors 6 and 7 of the voltage divider are connected accordingly to the fifth and sixth outlets of the MC 1, the outlet of measurement result transfer of the MC 1 is connected to the inlet of the reception of the binary code of a radio module 8, the discrete outlet of the radio module 8 is connected to the inlet of control of the power saving mode of the MC.

EFFECT: expansion of functional capabilities.
