CO2 monitoring, displaying on the train signs.
For more information about the train signs, see https://github.com/sheffieldhackspace/train-signs
For more information about the environment monitor, see https://github.com/alifeee/co2-monitoring
Note that the sensor is within the sign enclosure, so the measurements are probably not very accurate, as there is likely not much airflow into the enclosure.
This project consists of two folders:
./controller/which is for the Arduino which controls the sign (basically the same as https://github.com/alifeee/openbenches-train-sign/tree/main/controller). It listens to Serial on an RX pin, and displays any text it receives (terminated by a null character"\0") on the sign../monitor/which is a combination of https://github.com/alifeee/co2-monitoring and https://github.com/alifeee/openbenches-train-sign/tree/main/fetcher. It talks to the attached CO2 monitor and then sends the results to serial (to the Arduino Uno).
