Versatile Voltage-to-Pulse Train Converter Supports Sensor Data I/O (.PDF Download)

    Oct. 19, 2015

    When the need arises to convert voltage readings from an analog sensor into a pulse train, a low-end microcontroller offers a versatile solution. The design in Figure 1 uses an 8-pin PIC 12F683 to provide a pulse train that’s proportional to the sensed input voltage. This is useful, for example, when transforming a sensor signal into a format that’s compatible with a basic digital or GPIO input. The output operating range ranges between 0 to 500 pulses for an input voltage of 0 to 5.00 V dc...
