SECTION 7 TEMPERATURE SENSORS Walt Kester, James Bryant ...

because of low-level nonlinear outputs, the sensor output must be properly conditioned and amplified before further processing can occur. Except for IC sensors, all temperature sensors have nonlinear transfer functions. In the past, complex analog conditioning circuits were designed to correct for the sensor nonlinearity. These circuits often required manual calibration and precision

Electronic – sensing light and outputing voltage suitable ...

Electronic – sensing light and outputing voltage suitable for audio. audio light. I have an idea for a project where I use a pc fan to make an oscillator. The oscillation is created by the cycle of light/dark falling on a light sensor as the blades of the fan rotate. My initial research points to the use of the photodiode in combination with a op-amp to provide a suitable line audio output ...

Sensitivity and output settings of the temporary pacemaker ...

The output of a pacemaker is the current (measured in milliamperes, mA) which it produces as a brief pulse. The current is delivered in a brief burst, over about milliseconds. During this time, the pulse generator discharges a capacitor into the leads. Voltage between the electrodes increases suddenly to 5V, and drops slightly over this brief period (as determined by the lead impedance ...
