A temperature change is what this circuit is designed to detect to as it performs the function of a comparator. TL061 – a high speed JFET input single operational amplifier incorporating well matched, ...

This sensitive circuit is basically a comparator, detecting very slight temperature changes in respect to the ambient temperature. It was primarily intended to detect draughts around doors and windows ...

A circuit is a closed loop containing various components. Electrical current flows around the circuit. Scientists use symbols to represent the different components in a circuit. Symbols are simplified ...
