So, if you're designing a smart home project with your Raspberry Pi, make sure to include these sensors for a well-rounded experience.

By analyzing those patterns, an onboard Raspberry Pi microcomputer is able to determine the current water level to within an accuracy of plus or minus ~1.5 cm (0.6 in).

Introduction: Control Home Appliances From Your Smarthphone With Blynk App and Raspberry Pi. In this project, we are going to learn how to use Blynk app and Raspberry Pi 3 in order to control home ...

I was thinking there must be a simple sensor that could tell me when the water level has fallen a set amount and automatically run the "fill pool" zone on the Rachio.

The raindrop sensor detects the presence of rain by measuring the conductivity of water droplets on its surface. The setup involves connecting the sensors to the Raspberry Pi’s GPIO pins.
