perfecto. justo lo que necesitaba. llegaron rápido. excelente calidad
Can be connected directly to Arduino board since it supply 2.5Vdc offset (when powered at 5Vdc). Caracteristics: AC input: up to 250VRMS DC input up to 32Vdc (according to LM358 chip spec) Here is my test conditions: Module powered at 5Vdc: Input: 120VacRMS Output: up to 1VacRMS max (variable) + 2.5V dc offset (Output saturation occur at 0.86V) Module powered at 12Vdc: Input: 120VacRMS Output: up to 1.833VacRMS max (variable) + 5.887V dc offset. No saturation With AD736 chip, it can be used for measuring RMS voltage with Arduino.
fast delivery, and in good condition
Nicely made, perfectly adequate for the task at hand!!
Thanks, as I expected it is of good quality
Good voltage transformer module for use with Arduino or Nodemcu.
Good for isolating AC from Electronics and convert the signal to logic level in one module. Very easy working.
real useful
great for measuring the voltage delivered by a generator
Nice and easy to use
