ESP-32 Flight Datalogger – Adding Sensors

September 21, 2021 Patrick Gilfeather

Having code that is organized as blocks or objects opens the door for other possibilities. As the ESP32-Cam project progressed, the use of the I2C protocol from the current sensor led to the widening of the project scope. Among the current sensor were several shelved I2C protocol sensors. The hardware was already available, all that need to be done was merge its code base into the firmware development. Only a barometer sensor was added, which included a thermometer. The sensors…

ESP-32 Flight Datalogger – Turning Code into Blocks

September 14, 2021 Patrick Gilfeather

Developing firmware for hardware typically is not a ground up method. Many AVR and ESP projects that exist have been developed using pre-developed code. This can be the main code base or libraries that provide support. Libraries are easier to adopt into a project because they can be defined and called when needed. Code base reuse doesn’t offer this. Much of it is specific for the application it was developed for. As a result, the code base will need to…

ESP-32 Flight Datalogger – Power Requirements

September 7, 2021 Patrick Gilfeather

The last section was a design introduction of a data logging system and its operation. This section will cover the power requirement of that system starting with each of its components. Datasheets are the primary source for this information. Having enough power to operate the system for the duration of flight is the essential goal. If power loss occurs midway in flight, there is a chance that all data will be lost. Here is list of the components and the…
