I’ll show you how to use and calibrate both of these types of sensors, both with analog and I2C interfaces. After we get our sensors calibrated, we’ll use them to build a soil moisture meter using a Raspberry Pi Pico and an OLED display. We’ll then focus our attention on the main project in this video, an automated watering system that uses an Arduino Nano 33 IoT and works on the Arduino IoT Cloud. This will allow you to maintain your solid at a specific moisture level and monitor it from anywhere on the Internet, with both a desktop and mobile interface.
