Hi All and thanks for reading me.

I would like to complete the following project :

  • 5 data loggers (slaves) based on arduino with about 5 sensors each (low refresh rate)

  • Each Data logger is abble to answer to the master and send their data (Once per hour)

  • The distance max between Master and slave is 200 meters.

  • The master (arduino also) is able to send the data to internet once a day by GSM.

Could you please give me some input based on your experience to start this project.

What kind of shield coud i use for the Master <-> Multi Slaves communication.

Thank you very much in advance for your help.

You can use the nRF24L01+PA+LNA radio with directional antennas on the slaves aimed at the master. Use the TMRh20 library and the 'starping' example.

You could also use the Adafruit 433MHz or 915MHz breakout boards with the Hope radios. The RadioHead library has lots of examples for reliable linking. The RHReliableDatagram class allows numerous slaves. The Feather product line would also work.

This moderator can't be arsed to go to the hassle of merging threads across different sections of the forum, so he's locking it instead.
