Transmitter. The audio signal is coupled to the base of T1 (BC547) by an audio transformer. The T1 pre amplifies the signal. The transistor T2 (BD 140) drives the IR LED’s which transmit the sound as IR beams. The red LED provides fixed bias for theT2 as well as a power on indi...
Remote control for electronic flash units - has IR transmitter and receiver and threshold signal activated by integrating circuitThe flash gun control circuit (II) is a self-contained unit and the master unit (I) is linked to the flash gun by two sets of IR beams. One beam initiates the ...
Abstract: A circuit is described that transmitstemperature data over an IR link, thus allowing isolation of the temperature sensor. The circuit consists of an IR transmitter, an IR receiver, and a temperature sensor. The problem of obtaining temperature readings from points at potentials a few te...
The IR transmitter and receiver on breadboards for testI made this circuit for a project that i am currently making (Instant Cold Coffee Machine). I needed of a circuit, that can detect a light beam cut. The first circuit i made was a light/dark detector with photoresistor. Although it...

1.Both transmitter and receiver clocks are proper 2.In the receiver data lines we are able to see some transactions. 3.In the receiver control line we are able to see a pulse 4.In transmitter lines we arenot ableto see any transactions. ...
Now if there is presence of vehicles, the communication between the IR transmitter and the receiver is interrupted, i.e. the photodiode receives less or no amount of light from the IR diode and accordingly the base current to the transistor reduces, eventually making the conductor go to off ...
Step 2: IR Sensor's Working & Circuit IR sensor motion detection is used in this switch. This motion detector will detects the object crossing across the two IR sensors namely IR transmitter (Tx) and IR receiver (Rx) . When the object (Reflecting surface) is detected IR receiver receives ...
