This sensor hub is to connect two current sensors in parallel. The current of both sensors will be summarized and passed to the FC. The voltage measurement of the LiPo packs will be collected from both sensors and passed through the Hub to the FC.
The main purpose of this hub is to replace existing protection circuits (like an ideal diode) and to monitor, that both paralleled LiPo’s supply the same current to the system.
Since we monitor the current of both batteries, we will find out very early when a LiPo starts to fail… before it is too late.
If the difference in current is bigger than +/- 10%, the Hub will issue a warning to the pilot via a Power Led and/or buzzer (fast flashing) connected to the Alarm I/O.
If the difference in current is larger than +/- 20%, the Alarm output will be always ON to indicate the fault… the pilot should immediately land and check the batteries.
Additionally, there is a reserve relay contact (alarm) for the user to implement any desired function.
The I2C bus is for future integration.
To set up a complete system you would need:
1x Sensor Hub X2
2x Current sensor board:
HS-050-LV or HV = 2x50A = 0-100A Total
HS-100-LV or HV = 2x100A = 0-200A Total
HS-200-LV or HV = 2x200A = 0-400A Total
1x 2-6S BEC or 4-16S HYB-BEC
39mm x 31mm x 6mm / 7g without cables.
The board comes with 10cm connection cable (DF-13-6p <-> DF-13-6p) to the FC and 2x 10cm connection cables (DF-13-6p <-> DF-13-4p) to the sensor boards. If you need a customized cables in different length, then please order it separately.
