Introduction

The sensor module is responsible for taking telemetry from the environment, logging it to storage and reporting those measurements to other modules.

This page reflects the software design for the second revision of the sensor module

Data

Name	Data	Type	Size (bytes)	Sample Rate (Hz)
MS5611	Pressure Temperature	float float	32 32	100
BMP388	Pressure Temperature	float float	32 32	100
LSM6DSL	Accel X Accel Y Accel Z Gyro X Gyro Y Gyro Z	float float float float float float	32 32 32 32 32 32	100
LIS3MDL	Mag X Mag Y Mag Z	float float float	32 32 32	100
ADXL375	Accel X Accel Y Accel Z	float float float	32 32 32	100
TMP117	Temperature	float	32	10

*** Note that noted sample rates are somewhat placeholders and subject to change. Refer to Backplane PDR on data budget for more accurate numbers.

*** Some sensors also are not going to sample at exactly 100 Hz. Some sensors do sample at 104 for example

Name	Responsibility	Priority
100 Hz Telemetry	Read in sensor values sampling at 100 Hz and placing it on a queue for consumption	High
10 Hz Telemetry	Read in sensor values sampling at 10 Hz and placing it on a queue for consumption	Low
Ethernet Transmit	Transmit sensor data to other modules	Medium
Data Logging	Log sensor telemetry	Medium

Name	Responsibility
Ethernet Receive	Receive data from Ethernet. This will mostly likely be notifications from radio module that liftoff occurred to serve as redundancy in case lift off detection fails
