ENG-CANSAT-MISSION1-CAPTURE

Introduction

The following Wiring is used to capture

• Air temperature
• Air pressure

and transmissing the information via the RFM69HCW radio module.

Wiring

Wire the barometric sensor

The BMP280 is wired on the I2C bus of the Feather.

Wire the temperature sensor

Then connect the TMP36 sensor as follows:

• The pin 1 (on the left) to a power source (3.3V),
• The pin 3 (the the right droite) to the ground/GND.
• The pin 2 (middle one) to the A3 analogue input.

Wire the radio module

Finally wire the RFM69HCW radio as follows:

Feather M0 Express	RFM69
3V	VIN
GND	GND
MO	MOSI
MI	MISO
SCK	SCK
6	CS
9	G0
10	RST

Testing

Now, we will move forward in several steps.

1. Getting data from sensors + send them it over the serial connexion (to confirm good working) + transmit over radio
2. Testing the radio reception
3. Going autonomous (removing Serial Connexion waiting) + add the Lipo

LED and errors

x

Reading and transmitting data

This Arduino sketch would:

1. Wait for the serial connexion to be established before starting the sketch
2. Collect the sensor data
3. Send it to serial connexion
4. Send it over the radio connexion
