Hi I have two of these pressure sensors
https://m.pt.aliexpress.com/item/108117 ... s-Tank-etc
I managed to connect them successfully with raspberry and ADC ads1115.
The issue is that for pressure zero I was supposed to have an output of about 500 mV but I have around 800mv
This happens in both of the two sensors.
I have another sensor similar, but with max pressure of 15bar instead of the 5bar of the other two
In this one of 15bar I have the expected 500mV of output.
Any ideas why the sensors give more 300mV volts in the output.
One important note is that they were giving the 500mV previously
May I have broken the sensor with the pi and a multimeter?
Help here please
