A very simple temperature indicator circuit can be built by interconnecting a single transistor, a diode and a few other passive components. Using Transistor as a Heat Sensor As we know that all semiconductors have this “bad habit” of changing its basic characteristics in response to ambient temperature changes. Especially basic electronic components like transistors […]

RTD Temperature Meter Circuit
In this post I have explained the making of an RTD temperature meter circuit, and also learn about different RTDs and their working principles through formulas. What’s an RTD A RTD or resistance temperature detector works by detecting the difference or an increase in the resistance of the sensor metal when it’s subjected to heat. […]
