Like I mentioned this would be development board IoT board for Raspberry PI 2 and Arduino Nano.

Target for this project would be to keep the cost of the component as low as possible.

At this moment I did research for following components with their prices.

  • Wi-Fi ESP8266 $1.58
  • Temperature and humidity DHT11 $0.99
  • Barometric and preasure sensor $1.27
  • Sound detection sensor $0.73
  • Photosensitive brightness resistance sensor $0.73
  • Axis-Gyroscope-Accelerometer $1.75

Please share link if you find lower price then presented.

Please let me know if you would see any other module which can be used in this IoT platform.
