Stemedu DC0-25V Voltage Detection Module Voltage Sensor for Arduino Raspberry Pi (pack of 5pcs)

Q: How well does this unit work for a range between 0v to 1v dc?

It divides by 5. if all you need is a reading of 0 to .2v than it would work.

Q: Does this sensor work with a raspberry pi zero? i need to sense ac voltage (on/off). do you guys have anything maybe with an opto isolater

Sorry, for raspberry pi zero, you can not use this voltage sensor, you can use Voltage transformer module and ADS1115 module.

Q: Does this sensor work with a raspberry pi 4 b? thank you.

It is a Voltage divider of resistors that divides by 5. 25v in gives 5 v out for a input to a port that needs to measure voltage. I needed it for an Arduino, but you can also use it on a Raspberry Pi. It is only a voltage divider. You could make your own with 2 resistors, that's all that is on the sensor. I just didn't want to look around when a unit with the resistors readily available.
