Lagopus v2.0

[ArcticSnow]

Discussion and notes about v2.0 of Lagopus board

Goal

• continue with direct I2C communication
• up and down looking radiation sensors
• include new sensor (VEML7700)
• Improve packaging, weathering/installation/constrcuction
• review I2C sensors online to check if any could be interesting add.

State of development.

New lagopus will incorporate:
Lagopus A:

• MLX
• VL
• AMS AS7341
• VEML 7700
• compass+acc+gyro: https://learn.sparkfun.com/tutorials/9dof-sensor-stick-hookup-guide?_ga=2.72193690.861982949.1607436779-1010234314.1573465452

Some sensor require some protection, like the AMS will need epoxy (find which type) for waterproofing.

Lagopus B

• TMP117
• BME280
• SHT31

Then because of memory issue on the main we are thinking to build a SDI12 or I2C slave microprocessor (Arduino Nano or MKRZero) to handle the sensor directly and only be ON for sampling sensors

A GPS chip could be added to the arduino as well: Adafruit GPS breakout or Sparkfun Ubloc
