Introduction

The new soil moisture sensor uses Immersion Gold which protects the nickel from oxidation. Electroless nickel immersion gold (ENIG)  has several advantages over more conventional (and cheaper) surface platings such as HASL (solder), including excellent surface planarity (particularly helpful for PCB's with large BGA packages), good oxidation resistance, and usability for untreated contact surfaces such as membrane switches and contact points.
 
A soil moisture sensor can read the amount of moisture present in the soil surrounding it. It's a low tech sensor, but ideal for monitoring an urban garden, or your pet plant's water level. This is a must have tool for a connected garden!
 
This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance).
 
It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden. The DFRobot IO Expansion Shield is the perfect shield to connect this senor to Arduino.

  • IoT Plant Monitor
  • So, my wife wanted to have some small plants in the house. I didn’t, so we compromised, and got some plants. The only thing is that neither of us remembers to water them, so I wanted to build a sensor array to monitor the moisture content of the soil, and notify us when they needed watering. We’ve got 3 plants, all fairly close to each other, and I wanted to create an IoT project so that it could send an email notifi...
  • My ghostbusters proton pack
  • Hi all. Thought I'd share with you my modded Spirit Halloween proton pack. It's about 80% scale, which is plenty big enough for my 7-year-old son, and still looks decently sized on adults. As soon as I learned of this pack, 5-year-old me just had to get one. And I had just gotten my Arduino beginners kit a week earlier. I knew what had to be done :)...
