Espruino in the garden

Hi furuskog,

You could make a simple soil moisture sensor using two wires stuck in the soil and connected to 3.3v and A7, then just measure the voltage at A7 by doing something like..

var n=0,i=100;
while (i--) n+=analogRead(A7);

Then you can log the data from your soil meter and any other sensors in a google spreadsheet like this example http://www.espruino.com/Logging+to+Googl­e+Sheets

You could handle the alerts from google sheets as the there are add-ons which can email you etc

I made a similar garden thing which has sensors for light intensity, temperature, humidity and soil moisture http://forum.espruino.com/conversations/­302202/

Hope that helps
