Plant Monitoring system using arduino(s) and a web server to store and render data

Arduino Plant Monitor

Note: Work in Progress

This repository contains the Arduino Config and Node.js API. Frontend in progress (will be React or plain HTML with JS to consume the API).

Hardware

• Adafruit 2821 ESP8266 or other WiFi compatible Arduino.
• A battery may be desired depending on your use-case.
• Moisture Sensor(s) such as the Phantom YoYo.
• If using more than 1 sensor on the Adafruit or other Arduino with only one analog input, a multiplexer will be needed. I am using a 4051 currently.

Arduino Configurations

Direct Analog Input

If you are using an Arduino device with one or many analog inputs, use the plant_monitor_analog_only package in the Arduino folder.

• Set up WiFI under the Network Configuration section.
• Update the Sensors array with your pin(s) (if using the Adafruit 2821 no change is needed here).

Analog Input with Multiplexer

If you are using a multiplexer with a single analog input, use the plant_monitor_multiplexer package in the Arduino folder.

• Set up WiFI under the Network Configuration section.
• Set amount_of_mux_inputs to match how many devices you will run off of the multiplexer (if 2, set 2).
• Connect your sensors to the Multiplexer. It is important to start from y0 and count upwards as there is no way to detect if a sensor is plugged in or not.
• Edit s0, s1, and s2 to match your digital selection pins.
• Update your AnalogSensor Pin if not using the Adafruit 2821.
