Grove - Soil moisture sensor

This Grove sensor can measure the soil moisture for plants, for example. The soil moisture sensor consists of two probes that allow the current to flow through the soil and then determine resistance values to measure the soil moisture content. This can be used, for example, to decide whether the plants in the garden need to be watered or to automate the watering of plants. The sensor is very easy to use by simply inserting it into the soil and reading the output using an ADC.

Applications:

• Botanical horticulture
• Moisture sensing
• Consistency measurement

Features:

• Cost-effective: Ideal for students, makers and IoT developers as DIYers and prototype designers.
• Plug-and-play: Grove-compatible interface (data transfer) and two large pads act as probes (data acquisition).
• Beginner-friendly: Detailed start-up tutorials, numerous resources and projects on the wiki and in the community.
• Effective measurement: Based on soil resistivity measurement, high moisture leads to lower resistivity and vice versa.
