Batcus Active Single Phase Voltage Transformer Module AC Output Voltage Sensor for Arduino Mega

[Music] hello welcome to my channel today let's talk about how to use this zac mpt101b module to measure the ac voltage here there's a connector to measure the live wire for ac voltage on the right side here is the signal pin to communicate with the microcontroller and here is the calibration so as you can see here his life here is neutral here is a very dangerous spot which short circuit might happen or here is too near to each other so what you do is we need to install fuse in between so this is the example of a car fuse which can be used for ac as well this is a 5m fuse make sure it's compatible with the cable use the cable i use is about 0.5 to 0.75 mm square here we only require three pins the vcc is the power supply must be five volt and above the out is the analog pin to the microcontroller and the ground these two can be used either one so we only require three pins so in this p
