This fire sensor circuit exploits the temperature sensing property of an ordinary signal diode IN 34 to detect heat from fire. At the moment it senses heat, a loud alarm simulating that of Fire ...

Editor’s note: This article presents a good basic tutorial that will discuss several simple and low cost, but effective solutions for isolation of temperature sensors using optical couplers and ...

Most electronic engineers know that a transistor’s base-emitter voltage (V BE) has a temperature coefficient (TC) of about -2 mV/°C. However, for precision temperature sensors, “about” isn’t good ...

When testing cells, temperature can influence many of the cell properties. Therefore, when connecting a cell to a piece of cell test equipment, along with connecting voltage sense leads and ...
