Integrate LASS (Location Aware Sensing System) with TangleID and manage sensor data.

Getting Started

Follow the tutorial to build your devices.

1. Hardware

• Ameba RTL8195AM
• SHT31 or BME280
• Plantower PMS3003 (G3)
• OLED SSD1306

2. Wiring Diagram

• PMS3003 (G3)

Ameba	PMS3003
5V	pin1

4. Download and install the mbed Windows serial port driver

Windows serial configuration

5. Set up Environment

Ameba Arduino: Getting Started With RTL8195

6. Update Program To Ameba

• Copy airbox-with-iota/lib/ to Documents\Arduino\library

• Input your wifi SSID, wifi password, and location in airbox-with-iota/main/config.h

• Update program

• Keep your uuid

• Records Search Tag (uuid + 'C') on TheTangle(DEVNET)
  e.g.
  uuid : LASSPBUAUAXABBMBOBAB
  Tag : LASSPBUAUAXABBMBOBABC
  https://devnet.thetangle.org/tag/LASSPBUAUAXABBMBOBABC
