Long Range Ir Sensor Circuit Diagram. As we know oscillation frequency of 555 timer is decided by. You can use any tsop but you need to generate ir of respective frequency as tsop.
Ir sensor circuit diagram. It uses three infrared transmitting leds ir1 through ir3 in series to increase the radiated power. Please use ic base instead of directly soldering connection to ic because if your soldering iron is hot enough to crosse its maximum penetrating temperature the internal circuit of ic will get burn and then your ic is useless.
We are using tsop1738 as ir receiver so we need to generate the modulated ir of 38 khz.
By using this circuit we can increase the range of emitted ir radiation up to 100cm. It uses three infrared transmitting leds ir1 through ir3 in series to increase the radiated power. As we know oscillation frequency of 555 timer is decided by. Place all the components according to circuit diagram i given above.
