Bjong – User Manual – V1.0 - pg.28
The acquisition frequency (sampling time) can be set by the user based on the needs of the measurement
campaign, always keeping in mind that according to the settings, the battery life changes. Depending on
the measurement and battery life requirements you want to obtain, you will have to find the right
compromise.
The longer the sampling time, the longer the battery life.
The device will not activate the sleep mode (low consumption) until the APP is connected,
even if discontinuous mode is activated.
9.3 Data transmission
Data transmission can be activated both continuous and discontinuous mode. By activating this function,
the Bjong will send the data via modem allowing remote monitoring of the values read. The user can
choose the transmission frequency to prevent the system from being constantly connected to the
Internet, with significant management costs in the case of time contracts with your telephone operator
and in order to reduce the energy consumption associated with turning on the modem.
Data stored will be sent upon reaching the transmission period. The transmission frequency must be
chosen according to the frequency with which an operator could check the data remotely.
The lower the transmission frequency, the longer the battery will last.
The higher the transmission frequency, the lower the battery will last.
9.4 Freezing
Freezing is a particular mode in which the device does not perform any type of operation and disables all
peripheral devices, with the exception of the reed contact (magnetic) which allows subsequent activation.
The device is as if it were turned off.
To freeze the device, move the magnet closer, wait 5 flashes of all the LEDs (about 10 seconds in total)
and then remove the magnet. An animation of the LEDs indicates the transition to hibernation.
To reactivate the instrument, move the magnet closer. After 5 flashes (about 10 seconds in total) an
animation of the LEDs indicates that the freezing mode has been exited. At this point the green LED
remains on to indicate the possibility of connecting the App for configuration.
