Drones, UAV are mechanical systems but they are dependent on electronics telemetry systems for their positioning and geotagging in the real world
In this instructable, I'm gonna set a DAS system which provides Altitude, temperature and GPS coordinates of a UAV
Step 1: Altitude and Temperature
This chip is very delicate and sensitive to radiation, so do not expose it to direct sunlight. Once we get the height we can manipulate the data in the units we want
Step 2: GPS Coordinates
Thus by using the Antenna provided with the board we can easily get the GPGGA string with all the data received from the satellites.
Step 3: Connections
• Vin - 3V3
• Gnd - Gnd
• Scl - Scl
• SDA - SDA
Connect the antenna to the GNSS port. Rest everything is integrated within the board
We are gonna send the data through WiFi, thus connect the WiFi antenna to the board
Note: The connectors of wifi and GPS are very sensitive, be careful while connecting
Step 4: Code
In the code I take the readings from the altimeter, and concatenate with the string obtained from the GPS ie. GPGGA
the final string format looks like this: %Altitue$GPGGA.....
This string is then transmitted locally over wifi and can be viewed on the browser as in the output.
Step 5: Compile and Output
The final output is seen on the local browser by entering the ip addresss of the board which is to me obtained from the serial monitor right after uploading.
Copy paste the IP address in the browser and see the magic of the board
The time required for the page to refresh can be controlled in the code.
