Grove - Soil Moisture Sensor (ของแท้จาก SeeedStudio) เซ็นเซอร์วัดค่าในดิน

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.

Description
The Grove - Moisture Sensor is a kind of soil moisture detector that can measures 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. It can be used to decide if the plants in a garden need watering. It can be used 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
