IR Transmitter and Receiver Circuit Diagram

20/08/2015· We have use BC557 PNP transistor here, to reverse the effect of TSOP, means whenever the output is HIGH LED will be OFF and whenever it detects IR and output is low, LED will be ON. PNP transistor behaves opposite to the NPN transistor, it acts as open switch when a voltage applied to its base and acts as closed switch when there is no voltage at its base. So normally TSOP output …

How to Build an Infrared (IR) Phototransistor Receiver Circuit

So if you expose the IR phototransistor to an infrared light source such as an infrared LED, a TV remote control, a flame, or sunlight, the LED will light up, assuming that the infrared light is of the wavelength that the IR phototransistor is designed to detect. This is because the infrared induces a base current in the transistor, which causes sufficient current amplification to drive and light the LED.

Infrared Remote Control Switch Using CD4027 IC

The working of this circuit is simple it is using an IR sensor TSOP 1738, flip-flop IC CD4027, two transistors, and a few other discrete components. The IR sensor receives 38KHz IR pulses which are sent to a transistor Q1 for amplification. This amplified signal then goes to the clock 2 pin of the IC. The output of this IC will give voltage to transistor Q2 and it activates. Q2 then activates the 5V relay …

Simple Touch Switch using transistors - Elonics

For that purpose, we have to use transistors. The circuit will also work with just one transistor, but the LED doesn't glow bright enough. So we have used two. Tiny electric current flows through the skin when the end touch conductors are touched. This tiny current is amplified in magnitude by the first and second transistors and it finally passes through the LED. Refer to the circuit diagram for better …
