1. This circuit, based on a PIC microcontroller with a few added components, converts a sensor-based voltage into a 4- to 20-mA current loop. Shown is the circuit as originally drawn on a whiteboard.

The bandgap circuit also produces a voltage that is related to temperature. This voltage is sampled by SARADC and converted to digital signal. The digital logic receives clock and control signals from ...

This Design Idea describes a circuit employing a small microcontroller-based sensor module with only three connections: 5V dc, an RS-232 transmit-data output, and ground. A dedicated single-voltage ...
