Awesome Extras
This sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like traditional moisture sensors. It is made of a corrosion-resistant material giving it long service life. Insert it into the soil and keep an eye on your plants with real-time soil moisture data!
The sensor includes an on-board voltage regulator which gives it an operating voltage range of 3.3-5.5V making it compatible with low-voltage development boards (both 3.3V and 5V logic). To make it compatible with a Raspberry Pi, an ADC converter is required.
This sensor is compatible with the DFRobot 3-pin Gravity interface, which means it can be directly connected to the Gravity I/O Expansion Shield.
