Hardware
- BMP180
- MPU9250
- nRF24L01+ PA/LNA
- Arduino Uno
- Arduino Nano
Note: _Receptor.ino_ and Transmitter.ino_ should be uploaded to Arduino Uno and Arduino Nano respectively.
Configuration
Transmitter (Arduino Nano)
Takes data measured by BMP180 and MPU9250 and sends it through the nRF24L01+ PA/LNA. Data is divided and sent using two data packets (PACKET1 and PACKET2).
Connections
| Arduino Nano | BMP180 | MPU9250 | nRF24L01+ PA/LNA |
|---|---|---|---|
| Ground | GND | GND | GND |
| 5V | VCC | VCC | VCC |
| A4 | SDA | SDA | - |
| A5 | SCL | SCL | - |
| D9 | - | - | CE |
| D8 | - | - | CSN |
| D13 | - | - | SCK |
| D11 | - | - | MOSI |
| D12 | - | - | MISO |
| - | - | - | IRQ |
Receptor (Arduino Uno)
Differentiates incoming data packets and send them through serial communication.
Connections

Data analysis
_main.py_ divides incoming serial data by commas, it then graphicates all data.
Note: COM port might need to be changed depending on your connections.
Notes
- Time during which data is taken might be infinite (
timeRead = 0). - TIMEOUT time might vary depending on computer used.
