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 ...

A two-wire temperature transmitter using an RTD sensor that can be used in industrial settings to connect to the control room.

2. This more complicated current limiter has the advantage of much-lower voltage drop than the previous design, which is a critical factor in circuits operating from low-value supplies.
