Saaf water Hardware

Saaf water hardware collects data, displays water quality and estimates or sends data to IBM Watson IoT Platform via MQTT Protocol. To do so it comprises of 5 units namely:

• Power Unit
  • 5V 3A DC Power Adapter or equivalent Solar Panel with the appropriate battery and it's charge & protection circuit
• Microcontroller Unit (MCU)
  • ESP32 Dev Module
  • ADS1115 External ADC
• Sensing Unit
  • TDS Senor
  • Turbidity Sensor
  • pH Sensor
  • Electrical Conductivity Sensor
  • Waterproof Temperature Sensor DS18B20
• Visual Indicator
  • Adafruit Neopixel 16 LED Ring
• Telemetry
  • SIM800l Module
  • OR WiFi 2.4 GHz if ESP32 Dev Board

Getting started with Saaf water Hardware

There are 3 hardware codes:

1. Hardware Node: This is the Arduino code for the cellular device
2. Testing Hardware Node: This is the Arduino code for WiFi enabled device and testing
3. Simulator: This file can be imported in the IBM Watson IoT Platform to use the simulator

Procedure

Note: Setup your hardware and configure IBM IoT Platform (Click here for guide)

1. Install Arduino IDE
2. Configure ESP32 prerequisites in Arduino IDE
3. Copy all libraries from the library folder to your local Arduino IDE's library folder
4. Select hardware code and change the configuration information according to your setup
5. Upload!
