This is the AnySense project for MediaTek LinkIt 7688 board. The project conducts sensing tasks and reports the results to the LASS backend database via either MQTT or Restful API. The project are based on MRAA library in Python, and hopefully it shall run smoothly on the other MRAA-supported platforms.

Sensors supported (till 2018/1/7)

• Temperature and Humidity Sensor
  • HTU21d (I2C)
  • SHT2x (I2C)
• Light Sensor
  • BH1750FVI (I2C)
  • TCS34725 (I2C)
• Particulate Matter Sensor
  • Plantower PMS3003 (UART0)
  • Plantower PMS5003 (UART0)
  • Plantower PMS5003T (UART0)
  • Plantower PMS7003 (UART0)
  • Plantower PMSA003 (UART0)
• Gas Sensor
  • SenseAir S8 (UART1)
  • Sensirion SGP30 (I2C)
• RTC: real time clock
  • DS3231 (I2C)

How to run this program?

Please login you development board, and change to your working directory. Then, please follow the following steps:

1. Use the coommand to get the latest version of the codes:

   git clone https://github.com/cclljj/AnySense_7688
   

2. Install phao library by the command (optional, only needed if you want to use MQTT for data transmission)

   pip install paho-mqtt
   

3. Edit the file AnySense_config.py and change the configureations

   • Sense_PM: Enable PM sensor (1) or Not (0)
   • Sense_Tmp: Enable Temperature/Humidity sensor (1) or Not (0)
   • Sense_Light: Enable Light sensor (1) or Not (0)
   • Sense_Gas: Enable Gas sensor (1) or Not (0)   * Use_RTC_DS3231: Enable RTC (DS3231) (1) or Not (0)   ***
   • import xxx as pm_sensor: Change xxx to the corresponding module (or leave it unchanged if you don't need a PM sensor)
   • import xxx as tmp_sensor: Change xxx to the corresponding module (or leave it unchanged if you don't need a Temperature/Humidity sensor) * import xxx as light_sensor: Change xxx to the corresponding module (or leave it unchanged if you don't need a light sensor)
   • import xxx as gas_sensor: Change xxx to the corresponding module (or leave it unchanged if you don't need a gas sensor)

   ---

   • GPS coordinates: including GPS_LAT and GPS_LON
   • LASS settings: including APP_ID, DEVICE, and DEVICE_ID
   • MQTT settings: including MQTT_broker, MQTT_port, MQTT_topic, and MQTT_interval   * Restful settings: including Restful_URL and Restful_interval  

4. Run the main program by

   python AnySense.py
   

5. You can check the results on the console printouts or on the MQTT broker.
