1.1.2 Function description
Image1 S-SG
The S-SG in the car seat is powered by a built-in battery. The mechanical construction enabling the
exchange of the battery without special tools or soldering. The S-SG sends the status information of
the belt buckles and the status of seat occupancy sensors. The information is sent either at the time
when a change is detected, or every 25 seconds cyclically. The reading period of the AD value of the
resistance circuit in the seat occupancy sensor is 200 ms, it can be changed by software. The battery
voltage is read once a day. The algorithm for the evaluation of the battery status then sends the
current value in every Bluetooth message. The S-SG is contacted only at the time of data
transmission with the F-SG, otherwise it is in the (low power mode) power saving mode.
