A different IR system is a great option but I don't know how to design the circuit. The continuous current in my IR 333 is 100mA according to the datasheet but I tried to calculate the current using a multimeter and I saw that the current is only 60 mA (Can't understand how it's possible. If I...
I tried to connect 2 leds in parallel but it didnt really helpd me.
Its really strange:
From 0 meter to 2.5 meters it really works great. But above it ,i have to block the transmitter with my hand and only in this way after i realease my hand it detects again the signal.
Hello everyone,
I am trying to find way how to increase the range of IR. Im using transmitter Ir 333 and reciver TSOP348.
Also,I wrote a program in the microcontroller (Arduino) in order to make sure thats the trasmitter will transmit at 38Khz frequency at modulation frequency 100Hz.
Up to 2.5m...
