Standard Voltage Sensor Module 0-25V

• Size: 25mm×13mm/0.98″×0.51″(approx)
• TThis module is based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller.for Arduino analog input voltages up to 5 v, the voltage detection module input voltage not greater than 5Vx5=25V (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V). for Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.
• Voltage input range: DC0-25 V
• Voltage detection range: DC0.02445 V-25 V
• Voltage analog resolution: 0.00489 V
• Output Interface : “+ ” connected 5/3.3V, “-” connected GND, “s” connected for Arduino AD pins
• DC input interface red terminal positive with VCC, negative with GND
• By 3P connector, connect this module with the expansion of board for Arduino, not only makes it easier for you to detect voltage battery, can also use the IICLCD1602 LCD to display voltage
