{"title":"Qwiic Capacitive Soil Moisture Sensor","handle":"sparkfun-qwiic-soil-moisture-sensor-capacitive","url":"/products/sparkfun-qwiic-soil-moisture-sensor-capacitive","description":"This capacitive soil moisture breakout is designed for plant monitoring projects where exposed metal probes can corrode after time in the dirt. It measures moisture using a capacitive plate embedded in the board, managed by a CY8CMBR3102 Capsense® Express™ controller for improved durability in connected garden and agriculture builds.A ruler is printed directly on the PCB with Imperial and Metric units, so you can place the sensor at a repeatable depth and compare readings more consistently between pots or after replanting.For quick visual feedback, the board includes a blue STAT LED connected to a general-purpose output pin, which can be programmed to indicate when moisture drops below your chosen threshold. Communication is handled over I2C through the Qwiic Connect System, with two Qwiic connectors for solderless integration.Code packages are provided for both the Arduino IDE and MicroPython, including examples that help you calibrate the sensor for different soil compositions.Features:Capacitive sensing: Capacitive sensing over I2CController: CY8CMBR3102 ControllerI2C address: Software Configurable I2C Address (Default: 0x37)Ruler: On Board Ruler (Imperial and Metric units)Connectors: 2x Qwiic ConnectorsSTAT LED: Blue STAT LED (Connects to general-purpose output pin)Power LED: Red Power LEDSpecifications:Sensing/interface: Capacitive sensing over I2CController: CY8CMBR3102 ControllerI2C address: Software Configurable I2C Address (Default: 0x37)Ruler: On Board Ruler (Imperial and Metric units)Qwiic connectors: 2x Qwiic ConnectorsSTAT LED: Blue STAT LED (Connects to general-purpose output pin)Power LED: Red Power LEDA handy choice for automated watering, plant health logging, classroom experiments and other Qwiic-based environmental sensing projects.","vendor":"SparkFun","product_type":"Soil Moisture Sensor","in_stock":true,"options":[],"variants":[{"id":15577,"title":"Default Title","sku":"SF-SEN-30480","mpn":"SEN-30480","price":17.81,"on_sale":false,"in_stock":true,"available_quantity":79}]}
