IoT

This is a repo for exploring IoT (Internet of Things) using Single Board Computers (SBC).

1. Requirements

• Raspberry Pi 3 Model B+ –or– Pi Zero WH
• Enviro+ pHAT –or– Sense HAT
• U-blox7 GPS/GLONASS — (optional)
• Sabre Water Leak Alarm — (optional)
• Raspian (Buster)
• Python 3.7

2. Setup

2a. Local

• cd IoT
• mkdir data
• mkdir logs
• chmod 755 *.py

2b. Base (for Raspian Lite)

• sudo apt-get install git

• pip install spidev

• pip3 install spidev

• pip install RPi.GPIO

• pip3 install RPi.GPIO

2c. Azure IoT Central

• pip install iotc
• pip3 install iotc

2d. Enviro+ pHAT

• curl -sSL https://get.pimoroni.com/enviroplus | bash

2e. Sense HAT

• pip install sense_hat

2f. U-blox7

• sudo apt-get install gpsd gpsd-clients python-gps

• pip install gps

• pip3 install gps

  Testing:

  • cgps -s
  • gpsmon

3. Configuring

• cd IoT
• nano config.py

4. Running

• cd IoT
• ./enviro.py –or– ./sensehat.py — (required)
• ./ublox7.py — (optional)
• ./msiotcd.py — (required)

5. Monitoring

• cd IoT/data/logs
