Feature 1Since there are various electronic products at present, the voltage of the power supply is also different, if you want to detect, you need a suitable voltage detection module and controller. The upper limit of the input voltage detected by the analog interface of the controller is 5V, which means that voltages greater than 5V cannot be detected. |
Feature 2This voltage detection module of Stemedu can solve this problem and realize the detection of voltages greater than 5V. This module is designed based on the principle of resistance divider, which can reduce the voltage input by the red terminal interface by 5 times. |
Feature 3The upper limit of the analog input voltage is 5V, then the voltage The input voltage of the detection module cannot be greater than 5V×5=25V (if a 3.3V system is used, the input voltage cannot be greater than 3.3Vx5=16.5V). |
Output interface:
Because the AVR chip used by Arduino is 10-bit AD, the analog resolution of this module is 0.00489V (5V/1023), so the lower limit voltage of the voltage detection modules detection input is 0.00489V×5=0.02445V.
