Voltage Sensor Voltage Detection Module
Module Introduction:
This module is designed based on the principle of resistance voltage division, which can reduce the input voltage of terminal interface by 5 times. The maximum input voltage of Arduino analog is 5V, so the input voltage of voltage detection module cannot be greater than 5V × 5=25V (if 3.3V system is used, the input voltage cannot be greater than 3.3Vx5=16.5V). Because the AVR chip used by Arduino is a 10 bit AD, the analog resolution of this module is 0.00489V (5V/1023), so the minimum voltage detected by the voltage detection module is 0.00489V × 5=0.02445V。
Product Parameters:
● Voltage input range: DC0-25V
● Voltage detection range: DC0.02445V-25V
● Voltage analog resolution: 0.00489V
● DC input interface: the positive terminal is connected to VCC, and the negative terminal is connected to GND
● Output interface: "+" to 5/3.3V, "-" to GND, "s" to AD pin of Arduino
