IR receiver (10) circuit for processing a signal modulated infrared in carrier CONUN amplifier circuit (1, 21) and a demodulator (31) downstream of the amplifier circuit, provided uncomparador (411) which is designed to compare one being output signal (Bout) of the amplifier circuit (1, ...
IR Receiver circuit is very simple we just need to connect a LED to the output of the TSOP1738, to test the receiver. 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 lo...

To adapt the circuit to your needs, R1 must be properly chosen to get a high enough AC voltage signal. Then R2 and C1 must be properly chosen in accordance to the baud rate: Time constant must be high enough to be able to generate an avarage value without too much ripple....

On circuit board you can find the IR-receiver, which in our case is TSOP1738, but you can use any other type of IR-receiver which has frequency of 38KHz. For output power stage you can use triac TIC206 or TIC216. For loads more than 150W you must add a heat sink>You must be ...
As the battery voltage drops, the current through the LED will decrease as well. This will result in a shorter control distance that can be covered. An emitter follower circuit can avoid this. The 2 diodes in series will limit the pulses on the base of the transistor to 1.2V. The base...
The receiver is based on a ST-RX04 ASK receiver IC (IC3).The IC3 receives the transmitted code, decodes it to the original IR code and re transmits through IR LED (D1). The transistor Q1 is used to drive the D1 from the output of the IC3(pin2). ...
(L1 - L0) is long enough and the LED optical pulse is short enough, the optical pulses focused onto the photodiode will not overlap in time. A measurement of the path difference (L1 - L0) and the measured time difference of the electrical pulses from the photodiode receiver circuit ...
