DFRobot Moisture Sensor

• Monitor the soil moisture
• Helpful to remind to water in indoor plants
• Power supply: 3.3v or 5v
• Current: 35 mA

The DFRobot Moisture Sensor can read the amount of moisture present in the soil surrounding it. It is must to have this tool for connected garden to monitor soil moisture.

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.
