10 STCK. DC 0-25V Spannungsprüfer Sensor Messung Detektionsmodul für Arduino
9,32 €
10PCS DC 0-25V Voltage Tester Sensor Measurement Detection Module Terminal Sensor Module for Arduino Robot Smart Car Description: This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, Arduino analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because Arduino AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V. Package Included: 10 X Voltage Sensor Module.
