Why my soil sensor is readind the same in water or out water


#1

I just try to get some reading with my soil sensor and im getting the same in water or not, around 250
does any one know what am I doing wrong?


#2

Can you add some more detail, please?
How are you checking?


#3

first I put the soil sensor in the garden dirt and I have a 250 average reading next I went to get a glass of water and dump it in the ground and drop the soil sensor in and still get an average of 250 reading so next I try with a full glass of water and check still get a average of 250, the rest of the farmbot work great

I have the first gen from kickstarter if it help

What does the soil sensor read when in the open air?
No dirt, no water, dry…


#5

250 when is on the head open in the air and when I do a test with nothing on the head I get 1023

Maybe the sensor is bad.
Can you check the sensor for shorts, damage, water.
Sparkfun sells them cheap (like $6 USD)so may be order one to try out.
Because you read 1023 with no sensor, I think this points to the sensor being the cause.
