HomeKit Soil Moisture Sensor

About

This project will create an accessory that detects moisture level in soil and sends the information to Apple's HomeKit app.

As of building this, HomeKit doesn't support a moisture sensor. Instead of that we'll use a humidity sensor to show the moisutre levels.

Installation

• Install this library in Arduino IDE: https://github.com/Mixiaoxiao/Arduino-HomeKit-ESP8266
• Upload files in src to your NodeMCU (change Wi-Fi config before)

Components

• NodeMCU
• Breadboard Power Supply
• Soil Moisture Sensor

Circuit Diagram

Moisture Levels Details

Moisture Sensor sends data between 0 - 1024. 0 being maximum moisture and 1024 equals none. This is converted and sent to HomeKit as a percentage between 0 - 100. 0 will be no moisture, 100 will be maximum.
