MICROCONTROLLER RC-ADC WITH DATA TRANSMISSION FUNCTION VIA RADIO CHANNEL Russian patent published in 2022 - IPC H03M1/38 

FIELD: information and measurement technology.

SUBSTANCE: invention relates to information and measurement technology, in particular to wireless sensor systems. The positive power output of the radio transmitter is connected to the digital output of the microcontroller. The radio transmitter of the RC-ADC microcontroller implements two-level amplitude modulation of the OOK type (On-Off Keying, On-Off).

EFFECT: invention enables to expand the functionality of the RC-ADC microcontroller by providing the function of transmitting the conversion result over the radio channel. A RC-ADC microcontroller with the function of transmitting data over a radio channel contains a microcontroller 1, a reference voltage source (ION) 2, a resistor 3, a capacitor 4, a radio transmitter 5. Resistor 3 and capacitor 4 are connected by the first pins to the first input of the analog comparator (AC) built into the microcontroller 1, the ION output is connected to the second pin of the resistor 3, the second pin of the capacitor 4 is connected to the common power bus, the first pin of the analog signal source (ASS) is connected to the second input of the AC, the second pin of the ASS is connected to the on the common power bus, the modulation control input of the radio transmitter 5 is connected to the output of the timer/counter built into the microcontroller 1.
