In-situ Real-time Coastal Environment Monitoring

The Project

In my day job I build embedded systems and infrastructure to monitor the water condition around the He'eia fishpond. I also design custom self-contained data loggers that monitor water level, oxygen concentration, temperature, salinity, turbidity, pH etc. I also build the web stuff (mostly Python, JavaScript, MySQL, and RabbitMQ) that collect, store, process and present the data online in real-time.

Python Drivers for Sensors

Looking for Python drivers for the following sensors? Github HERE.

In addition to the "business logic" software, the repository includes Python drivers for
  • Aanderaa 3835 and 4330f oxygen optode
  • Aanderaa 4319 conductivity sensor
  • WET Labs FLNTUS turbidity and chlorophyll sensor
  • EZO series sensors from Atlas Scientific
  • MS5803-14BA and MS5837-30BA (absolute pressure sensors)
  • Si1145, HTU21D, TCS34725, TSL2591... (some modified from other libraries)
  • VEML6030, VEML6040 (high precision light sensors)
All drivers tested with the BeagleBone Black on Debian. Most work on the Raspberry Pi (Raspbian Lite Jessie+) without modification.

Note: I couldn't get the HTU21D humidity sensor to work with the Raspberry Pi A+. Something to do with the I2C hardware/driver on the RPi A+.
