Grove - Capacitive Soil Moisture Sensor (Corrosion Resistant)

The Grove - Capacitive Moisture Sensor (Corrosion Resistant) is a soil moisture sensor based on capacitance changes. It embeds with the powerful NE555DR which is a precise timing circuit, ideal for capacitive measurement.

Feature

• Corrosion-resistant design: Capacitive touch measurement system avoids probe oxidization.
• Powerful ICs embedded: NE555DR manufactured by TI working with built-in amplifier, good for capacitive measurement.
• Plug-and-play: Grove compatible interface(data transmit) and a long-straight pad function as a probe(data collecting).
• Starter-friendly: Detail start-up tutorials, abundant resources and projects provided in Wiki and Community.

Description

The Grove - Capacitive Moisture Sensor (Corrosion Resistant) is a soil moisture sensor based on capacitance changes. Compared with resistive sensors, capacitive sensors do not require direct exposure to the metal electrodes, which can significantly reduce the erosion of the electrodes. Hence, we call it Corrosion Resistant.

It is important to note that this sensor can only qualitatively test the humidity of the soil and cannot measure quantitatively. This means when the humidity of the soil rises, the value of the output decreases; conversely, when the humidity decreases, the output value becomes higher.

We have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs. Click to explore the Grove Sensor family and get started to Grove your Idea. For all Grove users (especially beginners), we provide you with guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product.
