Log pressure, acceleration and angular velocity of a model rocket using an ESP8622 via a simple webinterface.
Here's the altitude and acceleration plots of a misfire, thus it only reached ~35 meter:
TODO: Plots from a successful launch
The ESP simply sets up a hotspot named Rocket with the password rocketsrocks.
After that simply navigate to 192.168.4.1 to start a new log:
The log will automatically close when the file system is full. The log can also be stopped manually:
Finally the CSV file can be viewed and downloaded for further analysis:
The hardware consist of an ESP8622 (ESP-01 variant for its small size), a MPU-6500 (3-axis accelerometer and 3-axis gyroscope) and MS5611 (barometer). The voltage from a 1S LiPo is stepped down to 3.3V using a LT1763CS8-3.3.
All the components are simply soldered together and glued onto the battery. The whole package is then placed inside the rocket:
