Battery operated remote temperature sensor Drives 4 to 20 mA Current loop:
12/17/04 EDN Design Ideas / (added 1/05) You can remotely measure
temperature using a 4- to 20-mA current loop as long as 4000 feet and a
battery-powered, white-light LED driver. You usually configure this equipment to
provide a programmable, constant current to an LED from a battery source. The TPS62300
series of ICs, for example, converts a battery voltage of 2.... |

Ideas / (added 1/05) You can use a single-supply system to precisely
measure the temperature at a remote location with less than 1°C error over a 0 to
100°C range (Figure 1). The circuit includes T1, a low-cost AD590 temperature sensor;
IC1, an AD8541 rail-to-rail amplifier; four resistors; a trimming potentiometer; and
an ADC.... |

Four way remote control uses series transmission: 01/18/01 EDN - Design
Ideas / (addes 08/05) A simultaneous four-way remote-control system adheres to
size, cost, and reduced-complexity constraints and uses a series transmission to drive
parallel loads (Figure 1). You can use this system as long as the time constant of the
load is much larger than the total transmission time for all data. With these
considerations, this design can drive any object with four simultaneous controls as
motors. |
