What do you have for sampling rate? It's not eays to surely get the Max value
As far as I know there no negative voltage on the output. With an AC signal, we have an offset of 2.5Vdc. As a result you get 2.5V for a zero current and 5 or 0 V for the maximum.The theory is that you have to measure the RMS value of several points. Using Shanon, you obtain 2 x 50Hz (or 60Hz for US). That means 100-120 Hz. So if you sample it on the rate bigger than given - it's ok.Another way vould be to sample it higher and get the max value (Vpeak), after what multiply it by 0.707 and get the RMS value. But the Arduino ADC will not allow you to sample at 1kHz.
Can you please share how do you calculate the AC amp value?
Wow, nice job!After one year of experience, do you have any wood's resin on the walls?How did you calculated the power for it?
Thanks a lot!It's helpful.I will try to look for a relatively "clean" wood and a well dimensionned oven.I will give a feedback in half a year.
I'm wondering, why should we use a Wi-Fi instead of Bluetooth for a battery powered device? It has more power consumption. It has an excessive range, within a room.
