Damaged Soil Sensor (SKU: SEN0114, SEN0193)
Account cancelled 2016-06-20 13:04:42 2837 Views3 Replies Dear Technical Support,
Recently I have purchased few samples of the following products;
* Gravity: Analog Capacitive Soil Moisture Sensor (SKU: SEN0193)
* Soil Moisture Sensor Immersion Gold (SKU: SEN0114)
Although in the description of these products it was clearly mentioned that these are corrosion resistant, both of them are damaged completely after few days of use. Please refer the attached photographs.
I would like to know;
- Why they are so fragile? Is there any precaution that I should take?
- Is there any way to prolong their life time?
I expect your prompt reply.

In my case too, all of the SEN0114 used had no more plating on one of the branch after a month (see picture).
Conditions:
Vcc = 3.3V.
The sensor was continuously powered.
The corroded branch is the one connected to Vcc.
The soil was continuously wet. Indoor environment.
Has someone found an explanation for this phenomenon?
Except not powering continuously, what other solutions could help slow down the corrosion?

I happen to see your post here, and to help others, i'll still give the reply in the email, the reply as flow:
"As for the older version (SEN0114), it was understandable that during the longtime working in the soil, it would get eroded for the tempreture, humidity, conductivity. But we then design the SEN0193 to solve this issue, after been tested by us as well as our customer, it solved the corrosion problem very well.
So may I collect some info from you about your application enviorment?
- Do you have pictures for the earth details you applied the sensors into?
- What is the tempreture, humidity, conductivity ect. you know about the earth?
- Is there any hard things inside of the earth, like stone, glass, metal material... that would get the sensor (SEN0193) protection layer hurt?
- What other info you could offer?" Wendy.Hu
