# Tutorial About Sensor Bridge Circuit

Lots of explanation like wheatstone bridge, configuration, conversion, sensor, and sensor configuration are presented inside this tutorial. In the tutorial the reader can find things around the wheatstone bridge, voltage readings, wheatstone, and resistance.

The tutorial presents explanation like voltage, temperature, voltage dividers, and bridge. Below are some excerpt from this tutorial:

To implement Wheatstone bridge circuits for temperature measurements using thermistors. I. Introduction. From Voltage Dividers to Wheatstone Bridges A. Voltage Dividers – Using resistors R1 and RT, the voltage can be split depending on the ratio between the two resistors. Figure 1. Voltage divider circuit. Vab Vbc = R1 RT I ab = I bc V s = Vab + Vbc –    → V = R1 V + V s bc bc  RT  RT Vbc = Vs R1 + RT (1) Application: if RT is the resistance of a “resistance sensor”, e.g. an RTD (resistance temperature detector), a thermistor or a strain gauge, one can measure changes in RT by measuring Vbc (with Vs and R1 fixed).
