The ability to change resistance ... stretch sensors. Potentiometers, or pots, are basically voltage dividers: a method of dividing a given voltage down to a lower level. As the schematic shows ...

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

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

In previous articles I talked about fixed value resistors as well as variable ... resistance would increase in the desired gradual manner, reducing the current through the coil until the circuit ...

Often, it's necessary for a sensor system to compute the ratio of two capacitors. Doing so re-duces the transducer's sensitivity to dielectric errors from such factors as temperature. Furthermore ...
