Description Links Attachments

The SparkFun Qwiic Soil Moisture Sensor is a convenient and efficient tool for accurately measuring the moisture content in soil and similar materials. This sensor operates by using two large, exposed pads that function as probes. These probes act as a variable resistor, with the conductivity between the pads increasing with the amount of water in the soil. This results in a lower resistance and a higher SIG out. The sensor comes with a Qwiic connector, making it simple to connect and use.

The SparkFun Soil Moisture Sensor is easy to operate. Simply connect the VCC and GND pins to your Arduino-based device or a compatible development board. The SIG out you receive will then depend on the amount of water in the soil. One of the known issues with soil moisture sensors is their short lifespan when exposed to moist environments. However, this sensor has been designed with a gold-finished PCB (ENIG, or Electroless Nickel Immersion Gold) to combat this issue and enhance its durability.

Assembly and weatherproofing instructions, along with a simple example project, can be found in the Hookup Guide. This guide will provide you with all the necessary information to get started with the Soil Moisture Sensor.

The SparkFun Qwiic Soil Moisture Sensor is also equipped with a range of helpful documents. These include a Schematic, Eagle Files, a Hookup Guide, a Qwiic Resource Page, and a GitHub Hardware Repo. All of these resources are designed to help you get the most out of your soil moisture sensor.

The SparkFun Qwiic Soil Moisture Sensor is not just a tool but a comprehensive solution for all your soil moisture measurement needs. Its user-friendly design, combined with its durability and precision, make it an invaluable tool for anyone needing to monitor soil moisture levels.
