Voltage variation between sensors?

[peetdk]

Hi

I got two 3V sensors.

I tried to test them with multimeter and got:

Sensor 1:

Dry: 1,60V

100% wet: 1,23V

Sensor 2:

Dry: 0,6V

100% wet: 0,45V.

Is it normal with that variation?

I also checked that both of them got 3V.

Hi,

It's definitely not how it supposed to work.

Dry / in the air: should be somewhere around 0 - 0.1V
Wet / submerged in water: 2.7 - 2.9V

It looks like you may have a faulty sensor. I will contact you to arrange a replacement.

Kind regards,
