It consists of phototransistor L14F1 T1 datasheet: So across resistor R4 you get a replica in term of wave shape but not in amplipude of what you produce dstasheet the output of IC1 in the transmitter. AdjusterJan 15, Do you already have an account? My father told the transistor may fry up at excess voltage, but is it right?

By viviternDecember 6, in Infrared IR. Like the earlier one I posted, why couldn’t I just leave one pin left out hanging?

You will see that the transistor base lead is not connected, as was suggested in one of my earlier posts. The Darlington pair built around transistors T2 and T3 amplifies the photo-current generated by the photo-transistor T1.

Could you please post a diagram and fuller details of your application? AdjusterJan 12, And wouldn’t RF make more sense?

Posted December 6, Let us trash the safety issues as of now. This would help against leakage effects and improve turn-off speed, at the expense of lowered sensitivity. Jan 12, 2. That means its output goes high if it is initially low and vice versa every time it is clocked. In another posting I also sent you a link to a data sheet for the L14F1. Relay RL1 energises to switch on bulb B1.

Working of the circuit is simple. The amplitude would vary with distance and other factors such as the angle of arrival of the IR beam at sensor L14F1. Jan 12, 5. Nice circuit, but a few concerns. No, create an account now. This Dataseet voltage is fed to the junction of the inverting input of N1 and the non-inverting input of N2. The window comparator IC3 is designed such that whenever the input voltage is between 2 and datzsheet volts greater than 2V but less than 4Vits output goes high.
