The Mauch sensor hub is designed to connect two current sensors in parallel. This allows you to sense the individual voltage of two separate battery packs on your vehicle while in Parallel. The current of both sensors will be totalled and passed to the FC. The voltage measurement of each LiPo battery pack will be collected from both sensors and passed through the Hub to the Pixhawk Autopilot.
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.
As you can monitor the current of both batteries, you can see if one battery has any faults such as a damaged cell or poor performance which could save you from a crash.
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
Dimensions: 39mm x 31mm x 6mm
Weight: 7g without cables.
The board comes with 10cm connection cable (DF-13-6p <-> DF-13-6p) to the Pixhawk controller 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.
