Treedix 10PCS Voltage Detection Module Voltage Sensor DC0-25V Terminal Sensor for Arduino UNO Mega Robot Smart Car Geekstory

Specification:
The Arduino analog input voltage is up to 5V, so the input voltage of the voltage 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). Because the AVR chip used by Arduino is 10-bit AD, the analog resolution of this module is 0.00489V (5V/1023), therefore, the detection input of the voltage detection module is a small voltage of 0.00489V×5=0.02445V.
Voltage input range: DC0－25V
Voltage detection range: DC0.02445V-25V
Voltage simulation resolution: 0.00489V
DC input interface: the positive terminal is connected to VCC, the negative terminal is connected to GND
Output interface: "+" connects to 5/3.3V
"-" is connected to GND
"s" is connected to the AD pin of Arduino

Package Includes:
10*Voltage sensor
