Using a Thyristor and IR Sensor?
February 9, 2013
Hi am building this circuit.
I am using a VS1838B Infrared Sensor. On the right is a BC327-25 PNP Transistor and on the left is a MAC97A6 Thyristor. It seems to work well upon first use. then when you turn the battery case off and then back on again the thyristor is still turned on. If I pull one of the wires out and then quickly push it back in it will work again with the IR remote turning on the light and it stays on. but when I turn the battery pack on and off to reset it the Thyristor it doesn't reset or maybe the on off switch causes a spike or interference so it comes back on. Any suggestions on how to make it so the LED comes on when i put my remote control to it and then turns of and stays of when I turn the battery pack on and off.
I tried the resistor from Gate to Ground and that worked to prevent it from turning on whenever I switched the battery on and off however now it seems like it doesn't have enough juice to turn the thyristor on. Any ideas? Any suggestion on better components or different Thyristor?
Thanks for the help!
