Arduino Station

Sensor station built with Arduino-like boards.

Supported Boards Setup

There are various ways to enable internet connection on Arduino-like boards, either adding ethernet/wifi/GSM shields/modules or using ethernet/wifi/2G/3G integrated boards. Initially we are trying to focus on 3 less difficult and more affordable boards setup.

1. Particle Photon

• An Arduino-like (STM32) board with wifi connectivity
• Easy to use devtools, can do OTA on the web
• Porting from Arduino code is easy
• Good community libraries
• 1MB flash
• $19 USD
• Wiring difficulty: normal
• Setup instructions >>

2. NodeMCU

• Compact wifi module with Arduino-like capabilities
• Integrated well with Arduino IDE
• Useful libraries like http server/client, wifi manager, OTA...
• 4MB flash
• $8 USD
• Wiring difficulty: normal
• Setup instructions >>

3. ESP8266 Arduino

• Compact wifi module with Arduino-like capabilities
• Integrated well with Arduino IDE
• Useful libraries like http server/client, wifi manager, OTA...
• 1MB ~ 4MB flash depends on the hardware model
• $5 USD
• Wiring difficulty: a little complex
• Setup instructions >>

4. Arduino + ESP8266 Serial Wifi module

• Send AT commands in Arduino firmware to control wifi module via serial pins
• 32KB flash
• $27 USD (Using clones could be much cheaper)
• Wiring difficulty: a little complex
• Setup instructions >>

Supported Sensors

Since our first initiative is to build a PM2.5 sensor network, we only have one PM sensor support for now.

• Plantower PM Sensor
  • Currently only tested with PMS3003
  • 5V input, communicate via UART
  • Great accuracy according to comparative measurment on AQICN
  • $17 USD
