Ac Voltage Detection Using Optocoupler at Daniel Mcpherson blog

Ac Voltage Detection Using Optocoupler. 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. i have been using an hcpl3700 to detect 24vac, but they are large and relatively expensive. the circuit consists of two main parts, first is the bridge rectifier (db107) which converts the ac signal to dc and the second is the optocoupler. We cannot use this in that circumstance. traditionally voltage detection applications have used dc or ac optocouplers (photocouplers) where they fit in the. I have tested the design shown in the figure (ac. also, what if you are using a 3.3v microcontroller? the simulation suggests that you can accurately reproduce the ac line voltage from the input to the output.
