Push-pull sourcing and sinking, as it’s called, happens in two transistors ... Circuits in the sensor detect which output the controls need. Such sensors connect loads in light-on or dark ...

Using a transistor ... control circuits. We’ve embedded his twenty-minute video after the break. In it he talks about the use of transistors, the difference between NPN and PNP transistors ...

The circuit utilizes the light sensing property of LDR to activate the circuit. The LDR (Light Dependent Resistor) has very high resistance as high as 10 Meg ohms in dark which reduces ... of IC1 goes ...

A versatile signal-conditioning circuit ... input to a pnp type or incorporate it in the last stage of the sensor design to generate both npn and pnp outputs. The npn and pnp transistors used ...

It is also possible to produce circuits controlled by the heat ... from the heat-sensitive electrolyte, which acts as sensor, to the transistor circuit is sufficient. One sensor can be combined ...

IT is well known that changes in the d.c. characteristics of transistor amplifiers with temperature ... by minimizing these effects by suitable circuit design, or by the use of thermistors and ...
