Long Range Ir Receiver Circuit Diagram. The 555 timer ic operates in an astable mode. The circuit helps us to increase the range of transmitting ir rays.
Can someone please give me directions or diagram how to built this circuit. We are using tsop1738 as ir receiver so we need to generate the modulated ir of 38 khz. The circuit complexity increases in case you design the ir transmitter for good operation more than a extended distance for example 10 metres.
Ir sensor circuit diagram.
We are using tsop1738 as ir receiver so we need to generate the modulated ir of 38 khz. An ir transmitter and receiver pair forms a simple circuit. A resistor and capacitor are externally connected to the pin 2 and pin1 respectively short with pin 3 of 4047 ic. The majority of the ir remotes do the job reliably within a range of 5 metres.
