BeagleBone

How to Build BeagleBone Source Code

• Mount cmpt433/public folder to BeagleBone over NFS
  • See http://www.cs.sfu.ca/CourseCentral/433/bfraser/other/NFSGuide.pdf for more information
  • We'll assume that cmpt433/public on host gets mapped to $(HOME)/cmpt433/public/ on the BeagleBone
• $ cd BeagleBone
• $ make
  • Creates the executable plantManager in cmpt433/public
  • Copies sql/init.sql to BeagleBone's $(HOME)/cmpt433/public/myApps/init.sql
  • Copies scripts/createPlantDB to BeagleBone's $(HOME)/createPlantDB and makes this script executable

How to Run PlantManager Application on BeagleBone

• Run ./createPlantDB to create the plant database in $HOME/plants.db$
• Run ./plantManager to start the plant manager application

How to View Database in the BeagleBone

• # cd ~
• # sqlite3 plants.db

How to Run Web Dashboard

• Run $ npm install in website/plantmanager folder
• Run $ pip install -r requirements.txt in website/backend directory
• Run $ make website from the BeagleBone folder
• Run # ./start_flask.sh on the target to launch the web server
• Connect to http://target-ip:5000

ESP8266

How to Build and Upload ESP8266 Source Code

• $ cd esp
• Use PlatformIO to build and send to the connected ESP8266
• To view print statements on the ESP8266, open the serial monitor

How to Connect ESP8266 to Network

• If the ESP8266 does not have network credentials saved, it will create a PLANT WiFi Access Point
• Connect to this Access Point and enter the SSID and password of the network the BeagleBone is connected to
• ESP8266 will automatically connect to that network moving forward
• ESP8266 main.cpp needs to contain the IP Address of the BeagleBone

Pump

• MOSFET gate pin should be connected to the D0 pin of the ESP8266

DHT Moisture Sensor

How to Connect Moisture Sensor to BeagleBone

• SH (sensor's first pin): Humidity/Temperature
  • Connect to a digital pin: GPIO_39 - P8_4
• SM (sensor's second pin): Moisture
  • Connect to an analog pin: AIN1 - P9_40
• + (sensor's third pin): 3.3V/5V
• - (sensor's fourth pin): Gnd
• Don't forget to add pull-up resistors
  • BeagleBone analog inputs take in only 1.8V; sensor operates at 3V-5V max

How to Connect Moisture Sensor to ESP8266

• SH (sensor's first pin): Humidity/Temperature
  • Connect to a digital pin: D2
• SM (sensor's second pin): Moisture
  • Connect to an analog pin: A0
• + (sensor's third pin): 3.3V/5V
• - (sensor's fourth pin): Gnd
