tinyMonster - Analog Opto-Isolator
### DESCRIPTION
We can easily find many types of digital optocouplers but its very rare to see any analog optocoupler application especially in hobby electronics. Even though its very essential in many type of analog circuits especially in current and voltage monitoring/measuring circuits where input and output side should have isolation. If someone is measuring/monitoring the high DC voltages or current ,and its also driving inductive loads, then it can easily damage MCU or any other measuring hardware. To solve this sort of problems analog optocouplers are used.Here I am sharing circuit of one of analog optocoupler using easily available components.
tinyMoster - Analog Opto-Isolator module to provide ground isolation between 2 analog signals
### TECHNICAL DETAILS / COMPONENTS
Arduino, ESP8266, STM32 compatible output.
Applications:
High Current and Voltage Measurement
Low cost analog isolation
