Long Range Ir Transmitter And Receiver Circuit Diagram. The majority of the ir remotes do the job reliably within a range of 5 metres. A typical ir sensing circuit is shown below.
The 555 timer ic operates in an astable mode. Here is a simple circuit that will give you a pretty long range. It uses three infrared transmitting leds ir1 through ir3 in series to increase the radiated power.
To increase this range we are adding one more transmitter ir led.
Normally the range of an ir radiation from a normal ir led is 2 10cm with detection angle 35. It means we can increase the ir transmitting distance multiple times us. Normally the range of an ir radiation from a normal ir led is 2 10cm with detection angle 35. Here the long range distance infrared transmitter circuit give you extra power for your infrared transmitter.
