Please contact Ted for anything you want to know. 

How to use:
1. 
Power up. If you leave the sensor in the air, It shows 0.0 because of no water at all. 

2. Bury the sensor into the soil close to the root of your favour plant. It shows how much water the soil can hold. A greater number implies more water remaining in the soil.  As shown on the picture below, the number of  37.1 indicates that fine garden soil can keep a lot of water. 



3. (English stick is coming soon. ) 
Press the "menu" buttom once to modify your setting for "on" criteria at a less number. That means your pump will start running when soil moisture is lower than you set.
Press twice for "off", it must be a greater value but not too high so that your pump will be switch off when the soil is wet enough. 
For example the nice garden soil above, I can set the switch "on" when the soil moisture is lower than 5 and "off"  when it is higher than 30. 


Attention:
1. There is a limit of maximum value for your soil water content. 
You can use this machine to test how much water your soil can keep. As shown below the sandy soil can just keep 9.0 when it actually is pretty wet. 
As a result, I set the "off" criteria value at 8.5 (or any value less than 9.0) otherwise the pump will keep running until the end of world.

We can prepare a set of garden watering kit for you. 


And a pump for you
