The Mauch HS-200-HV high-current sensor board monitors a drone's power system with precision. It is designed for demanding applications and accurately measures both current and voltage from high-voltage batteries of up to 14S.
The listing says it is crucial for telemetry, flight-time estimation and battery management in heavy-lift and industrial UAVs.
It measures up to 200A continuously and comes with two 10cm 10AWG silicone wires already attached.
High-precision sensing: current and voltage measurement.
200A continuous: for heavy-lift and industrial drones.
High-voltage batteries: up to 14S.
Pre-attached wires: 2 x 10cm 10AWG.
Vital telemetry: data for the flight controller.
Robust design: made for demanding environments.
A current and voltage sensor board sits in the main battery line, between the battery and the rest of the aircraft. A Hall-effect sensor measures the current without adding a large resistor to the path, and a voltage divider scales the battery voltage down to a level the flight controller can read. The board then sends both values to the flight controller as analogue signals, which it uses for battery-level warnings, failsafe decisions and flight logs.
The sensor board itself does not power the flight controller. It needs a separate regulator (a BEC) that supplies the flight controller, GPS and telemetry modules. Choose a BEC whose input range matches your battery, and connect the sensor's signal cable to the power-monitor port of the flight controller.
For accurate readings, set the voltage divider and amps-per-volt values in the flight controller's battery monitor to match the board, and check the reported voltage and current against a multimeter and a known load. A wrong scale factor can make a battery look fuller than it is. Solder the heavy-gauge wires carefully and protect the joints with heat-shrink.
