- Purpose and reliability: In scientific experiments and industry, accurate measurement and control of current and voltage are required. This voltage and current sensor module is safe, reliable and highly accurate. - Current range and baseline output: If the voltage sensor module does not detect the current, the output voltage is VCC/2. The module can measure plus or minus 30 A current. It uses a 5 V power supply and includes an on-board current indicator LED for quick status. - Analog output and precision: The module can measure plus or minus 5 amps, corresponding to the analogue output 185 mV / A. - Design and usability: The terminal sensor module is small and light in weight, and the needles on each plate are marked, which is convenient for connection and use. - Applications and scenarios: Use in laboratory experiments and prototype testing with microcontrollers (eg, Arduino) to monitor load current. Use in power supply or battery discharge testing to track current consumption. Use in motor control or load monitoring in embedded systems, benefitting from a compact, clearly marked connection interface.
