Description

The Grove - Moisture Sensor can be used to detect the moisture of soil, to judge if there is dampness around the sensor. It can be used to decide if the plants in a garden need watering. It can be used in gardens to automate watering plants. It can be used very easily by just inserting the sensor into the soil and reading the output using ADC.


NOTE: This sensor is not hardened against contamination or exposure of the control circuitry to water and may be prone to electrolytic corrosion across the probes , please use it for PROTOTYPING ONLY.

hello Please I want to know if the output of this sensorgives directly the value of relative humidity or a voltage that I have to convert it?

Hi,if you use the example code we offered,it's not a value of a voltage.It's a number relate to humidity. But it's not a precise one,instead just positive correlation.

I have a question about unit of humidity. They say that dry soil, humid soil and water are represented by values 0-300, 300-700 and 700-950. I want to know what is unit of the value, like ml/cm3 or percent? How can it convert humidity to value?

Hi Yu~ It is just a value reflect the humidity of soil.We do not standardization.Regards.

Hi I can't give you a specific number.Only a experiential area,let's say a medium size flowerpot with 20cm diameter.

What about durability? can it support six month under ground?

Probably yes, but there are too many variables to consider. I would say 4 to 8 months as maximum and maybe you can prolong it life using it not often (1 reading every 10 or 30 minutes or even longer). The problem is the design. Also consider that you use this sensor to monitor edible plants there is the risk of contamination, the copper of the electrodes will end up in the soil and thus the plant. Would be nice if Groove would do a capacitive moisture sensor instead.

If I power it up with 3.3 volts, Can it be used with a beaglebone black?I think I will need a voltaje divider, but What about current?Sorry if it's to easy, Im a newbie to this.Thanks

When I use this sensor in water, is it possible to detect how much of the sensor electrodes is under water, i.e. use this sensor as a water level indicator?

You'll have to select the 5cmx10cm option. Always select the option where both dimensions are greater than your actual dimensions.The ordner number can be anywhere on your silkscreen, I always put it where I have room for it and create a little
