Task: Develop a weather station that will encrypt data between transmitter and receiver
The Transceiver:
It consists of an Arduino Nano board, which will record the data on atmospheric pressure, temperature, and altitude provided by the BMP280 sensor. The data collected by the sensor will be encrypted using 256-bit AES encryption and transmitted to the receiver via the NRF24 module.
How to connect the parts:
- The NRF24 module to the Arduino Nano board:
SCK Pin of the NRF module to Digital pin 13 of the Arduino Nano: SCK → D13
MISO→ D12
MOSI→D11
VCC→3.3V
GND→GND
CNS → D10
CE→ D9
- The BMP280 module to the Arduino Nano board:
VCC→ VCC 3.3V
GND→GND
SCL→A5
SDA→A4
