SparkFun Qwiic Soil Moisture Sensor (Capacitive)

The SparkFun Qwiic Soil Moisture Sensor (Capacitive) is a durable and reliable solution for monitoring soil moisture levels without the risk of corrosion. Utilizing a capacitive plate embedded within the board and controlled by the CY8CMBR3102 Capsense® Express™ controller, this sensor offers a long-lasting performance perfect for garden and agricultural projects.

This sensor is ideal for anyone looking to maintain precise moisture levels in their plants. With an integrated ruler on the PCB, you can easily measure the depth of the sensor in both metric (millimeters) and imperial units, ensuring accurate and consistent readings across various pots or after replanting. This feature is particularly useful for those who need to track moisture levels at specific depths.

For quick visual feedback, the sensor includes a blue STAT LED that can be programmed to light up when moisture levels fall below a set threshold. This allows for easy monitoring at a glance, making it simple to know when your plants need watering.

The sensor connects via the Qwiic Connect System using I2C, eliminating the need for soldering. Additionally, SparkFun provides code packages compatible with both the Arduino IDE and MicroPython, guiding users through the calibration process for different soil types. This ensures you receive accurate data tailored to your specific gardening needs, helping to keep your plants healthy and thriving.
