Task Description

  • The sensor head mount is a critical part of the science mechanism that is used to collect soil data

  • There are three main types of sensors located on this mount:

    • Soil moisture sensor (SEN0114)

    • CO2 sensor (SEN0219)

    • Temperature and humidity sensor (DHT22)

  • The current sensor head designed in CAD is incomplete (MR22-SC-A0036)

    • Sensor head parts are interfering with the main assembly, and all of the sensors may not be oriented properly with respect to soil samples

  • The sensor head should complete the following functions:

    • Allow the dinolite microscope camera to be rotated and refocused

    • Allow the moisture sensor to collect data from the soil

    • Allow the C02 sensor to collect data from soil

    • Allow the temperature and humidity sensor to collect data from the soil

  • The owner of this task would be responsible for redesigning the sensor head mount and ensuring all functions above are possible.

Task Breakdown

  • Determine application specs for each sensor
  • Design 3D printed sensor head mount to allow each sensor to interface with the soil properly
  • Conduct a preliminary design review with the mech lead, and determine the scope of changes required if necessary
  • Update the top-level CAD model of the 3D printed sensor head, ensure the functionality of the entire read head with dinolite camera
  • Fabricate all required parts, and assemble them onto the science module

Progress Journal

  • Austin Tailon Huang

    • Task created

  • Egor Gorelyy

    • Waiting to get clarifications from the science lead on whether the DHT 22 sensor and CO2 sensor can be inserted right into the soil or only lowered near it

  • Egor Gorelyy

    • There was unclearness on the Science subteam as to whether the sensor needed to be submerged in soil or could detect from close proximity

      • Same unclearness also about whether it has to be in a vacuum (or sealed environment) or not

    • Hooked up CO2 sensor to an Arduino, and did some preliminary tests. Asked science lead to come in at some point and test.

  • Egor Gorelyy

    • Designed a design for how each sensor will be applied and created some designs for the entire sensor head

    • Had the preliminary design review for the project

  • No labels
