· IR Range Extender Concept. The idea of this circuit is to feed the IR data from an IR transmitter into the transmitter input of an RF module through an IR sensor, and transmit the data in air so that the distant RF receiver module is able to receive the data. After receiving the data the RX would decode it and convert it back to IR based data, which could be used for triggering the relevant IR ...
· It utilizes the easily accessible IR sensor which is TSOP1738. The IR sensor has a “PIN photodiode” and an FET signal speaker encased in an “Epoxy case”. The circuit is straightforward and utilizing just three segments. The primary segment of the circuit is a TSOP1738 IR sensor. Here we are going to build an IR Remote tester circuit utilizing the TSOP1738 IR Receiver sensor circuit ...

· This circuit can be used to operate a VCR or CD player from another room. It’s really an infrared signal repeater. The signal from the remote is received and then retransmitted over wires to an infrared LED. The beam from the LED is then picked up by the receiving window on the VCR or CD player. The visible light LED (LED1) in series with the IR unit (LED2) is used to indicate that the ...

· Sampling comparator circuit with adjustable resistance R3 and general operational amplifier LM358 as the core; Sound Output and Display Circuit. A sound output and display circuit with transistor 9012, V1, V2, buzzer Y1, and light-emitting diode D3 as the core components. The infrared sensor circuit can also realize the situation below.
· Remember, the input IR frequency focused towards the TSOP sensor must be oscillated at a 38 KHz frequency, otherwise the TSOP sensor will not respond. This frequency may be slightly different for the different variants of the TSOP sensors. The Output Waveform of the Sensor. The output waveform indicates how the output of the IC oscillates between a positive (initial status) and negative ...
The latest addition to my collection of Infra Red (IR) Repeater circuits. The Mark 5 is a much improved version of the Mark 1 circuit and has increased range and sensitivity. It is also immune to the effects ofambient light, daylight and other forms of interference. In addition it works with IR modulation freuencies in the range 30 to 120kHz making the Mk5 circuit the best choice for ...
InfraRed (IR) Sensor/Detector Circuit. The IR circuit described below is mainly designed for liquid level detection or proximity detection. The IR sensors used here are an IR LED and an IR photo diode. The circuit operates by detecting the distance from the target by reflection of an infrared beam. The biggest advantage of this circuit is that there is no physical contact with the liquid whose ...
An IR detector module receives IR signal from remote control and two IR leds are re-emitting the signal to the appliance. You can place the IR emitting leds close to the device you would like to control using some wire and keep main unit close to remote control location.
