Product description
A Hall-based current sensor enables precise measurement of direct currents up to 50 amperes without an ohmic shunt resistor in the current path. The module measures the magnetic field strength around a current-carrying conductor and outputs the current as a proportional voltage.
The output voltage is 100 millivolts per ampere and can be connected directly to the analog input of a microcontroller. The wide operating voltage range of 3.3 to 5.5 volts eliminates the need to adapt to different logic levels. The component already includes a filter circuit that suppresses high-frequency interference and provides stable measurement values.
The current sensor is suitable for applications such as monitoring batteries and power supplies in robotics projects, controlling motor currents in high-performance drives, or measuring load profiles in decentralized power grids. A particular advantage is the ability to detect overcurrents and then trigger switching actions without interrupting the measurement path.
Operation requires only the sensor's power supply and a connection to the controller's analog input. The current path is established via the soldered connections for wires with cross-sections of up to 1.4 millimeters; adapters must be obtained for thicker cables.
Safety information
The current sensor is intended exclusively for building prototypes and for testing and development purposes and is not suitable for installation in household electrical circuits. Work on or near electrical installations must be carried out by qualified electricians. For current loads exceeding the specified range or if there is any uncertainty about the current path, consult a qualified electrician before commissioning.
