Integrated voltage and current detection module

Product introduction

Current sensor is a kind of detection device, which can feel the information of the measured current, and transform the detected information into an electrical signal meeting the needs of certain standards or other required forms of information output according to a certain law, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

The voltage detection module is designed based on the principle of resistance voltage division, which can reduce the input voltage of the terminal interface by 5 times. The maximum analog input voltage of Arduino is 5V, so the input voltage of the voltage detection module cannot be greater than 5V × 5 = 25V (if 3.3V system is used, the input voltage shall not be greater than 3.3V × 5 = 16.5v), because the AVR chip used by Arduino is 10 bit AD, the analog resolution of this module is 0.00489v (5V / 1023), so the minimum detection input voltage of the voltage detection module is 0.00489v × 5=0.02445V。

The integrated voltage and current detection module can be selected according to its own needs. After connecting it with main controllers such as Arduino uno, it can detect the current (< 3a) or input voltage value (< 25V) of the load circuit. There is no need to connect a separate current sensor or piezoelectric sensor for detection.
