Plant Watch

A client and server python application to enable monitoring of plants through a raspberry pi-powered sensor suite.

UI is powered through Streamlit hosted on the local network on port 8501.

Hardware

• Raspberry Pi (tested on a 3B+ running Raspbian OS Lite on Debian Bullseye)
• Grove Base HAT for Raspberry Pi Zero
  • Grove DHT11 Temperature and Humidity Sensor
    • Plugged into port labelled A0
  • Grove Capacitive Moisture Sensor
    • Plugged into port labelled PWM

Pre-requisites

1. Raspberry Pi (server) with Python installed and additional hardware attached
   • SMB share configured to enable file sharing over a network
2. Secondary machine (client) with Anaconda installed and an env created from the environment file

n.b. It may be possible to run both server and client code on a single device such as a Raspberry Pi 4.

QuickStart

1. Clone this repository to both the server and client machines
2. On the server start plant_log.py
   • This start the sensor logging
3. On the client start plant_watch.py
   • This starts the streamlit UI on http://localhost:8501

Data Flow

1. Load historical data for configured sensors
2. Display most up to date data
3. Dynamic update of relavant tables
4. Dynamic update of relevant chart

Features

1. Detct time since last watering
   • Some % change in the moisture level
2. Estimate time till next watering is required
   • Some threshold % of moisture
3. Display most up to date information from sensors
