Seeed Grove - Moisture Sensor

Grove - Soil Moisture Sensor can measure soil moisture for plants. The soil moisture sensor consists of two probes that allow the current to pass through the soil and then obtain resistance values to measure soil moisture content.

This Grove - Soil Moisture Sensor can be used to decide if the plants in a garden need watering. You can also use soil moisture sensors in gardens to automate watering plants. It can be used very easily by just inserting the sensor into the soil and reading the output using ADC.

Features

Cost-effective: Great for students, makers and IoT developers as DIY and prototype design.
Plug-and-play: Grove compatible interface(data transmit) and two large pads function as probes(data collecting).
Starter-friendly: Detail start-up tutorials, abundant resources, and projects provided in Wiki and Community.
Effective measurement: Based on soil resistivity measurement, high moisture resulting lower resistance and vice versa.

NOTE: This sensor is not hardened against contamination or exposure of the control circuitry to water and may be prone to electrolytic corrosion across the probes, please use it for PROTOTYPING ONLY.
