Sensor mount design
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.

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
25 Oct 2022 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.

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
