• The device takes temperature and humidity every 3 hours and saves the information
• The device will make 8 backups and send them once a day
ADVICE FROM ADEUNIS: For pure periodic sending it is advisable to set the acquisition period
Yes
to the desired backup period in order to gain autonomy (here 5400 corresponding to 3 hours).
Be careful about backup and sending values that depend on the network used and its band-
width.
Note: for a transmission without history, set the register 301 (transmission period) to 1 so the
device will send a frame at each backup.
