nRF24plus and Atmega328P radio probe Red_V02
The weather data-logging radio probe project originated during the construction of my "MEGA CLOCK 6 RGB LED 7-segment display" in 2019: https://www.elektormagazine.fr/labs/mega-clock Following that project, in 2020, I set out to build two radio transmitters designed to send sensor data to the clock. However, the connections made to the nRF24+ module at that time differ from those typically found in ATmega328P-based designs. The initial PCB also included several features that proved unnecessary in practice

Radio transmitter
North sensor -> DS18B20 => data T°C
Sud sensors -> GY61P --> Si7021 => data T°C
=> data %HR
--> BMP280 => data hPa
-> AFB-MR1A => data °(wind angle)
Radio receiver
Wind replica

Subsequently created other devices equipped to receive and process the data transmitted by the sensors.
METEO_LOGGER: This module displays data on a TFT LCD and records it to an SD card.
It allows you to keep a complete history of environmental measurements. https://www.elektormagazine.fr/labs/part-3-grow-data-radio-visio-logger I2C_CLOCK:
A clock with four RGB displays using an I2C bus.

I subsequently added the transmission of the wind direction angle value to the south probe code.
