Optocoupler Circuit Mains at Andrew Patten blog

Optocoupler Circuit Mains. Want to check if you left your lights on remotely, need to detect the zero crossing point for your dimming circuit or do you just need to interface a 230v signal to your arduino? I need to know for what i c current of the optocoupler i need to design. I am trying to detect line voltage (230v ac, if the supply is on/off) by a microcontroller with the help of an ac optocoupler. Many microcontrollers have internal pullups as options on at least some of their pins. I'm designing an optocoupler circuit whose output will be give to one of the arduino input pins. The simplest is then to connect the opto output between a pin with internal. Optocouplers can be ideally used for creating a perfectly isolated coupling across a low dc control circuit and a high ac mains based triac control circuit. For that i plan to use this circuit: The optocouplers i have evaluated. I want to optimize the resistors from if current in order to lower the power (w) they use so they. I am trying to sense mains with an esp32.
