Hello all,
I would like to build a sound reactive WLED system, which shall control a 230V 500W floodlight. It has to be exactly that one, it’s defined by external constraints.
It should be ok - should
the safest way is to measure the input current from SSR (change for the test the ESP-output with a DVM)
Is the current low enough for the I/O pin? Or find out a datasheet for SSR, what will tell you this parameter.
If the current to high, you can use a small transistor. npn or a MOSFET. Rundabout 1 k between base and output, emitter to GND and collector to (-) from SSR!!! (+) SSR to 5V
Maybe you must invert the output signal (easily on config website from ESP)
I’m glad to hear that!
According to the seller’s information the input current is specified as following: control current: DC:, 3~25mA, AC:12mA
I use the same SSR type in an application with an ESP8266, whose GPIO max current is specified as max 12mA, but ESP32 has a max GPIO current of 40mA.
So I’ll set up a prtotype and measure and test.
Thanks for your feedback!
