FIELD: electricity.
SUBSTANCE: microcontroller measuring converter for resistive sensor contains microcontroller 1, resistor 2 and resistor 3 (resistive sensor), resistors 4 and 5, integrating element 6. Resistors 2 and 4 by their first outputs are connected to negative terminal of voltage source, the first output of resistor 3 is connected to output of pulse-length modulator of microcontroller 1, the first output of resistor 5 is connected to positive terminal of voltage source, the second outputs of resistors 2 and 3 are connected to input of integrating element 6, the output of which is connected to input of analog comparator of microcontroller 1, to the second input of which the second outputs of resistors 4 and 5 are connected.
EFFECT: high accuracy of conversion.
