Package Includes: 1 Piece x Voltage Detection Sensor Module
This is a simple but very useful module which uses a potential divider to reduce an input voltage by a factor of 5. The Voltage Detection Sensor Module 25V allows you to use the analog input of a microcontroller to monitor voltages much higher than it capable of sensing.
For example with a 0-5V analog input range, you are able to measure a voltage up to 25V. The module also includes convenient screw terminals for easy and secure connection of a wire.
This module is based on the principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller. 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).
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: DC 0-25 V
Voltage detection range: DC 0.02445 V to 25 V
Voltage analog resolution : 0.00489 V
You can also use the IICLCD1602 LCD to display voltage.
By 3P connector, connect this module with the expansion of board Arduino
GND – This is where you connect the low side of the voltage you are measuring. Caution! : This is the same electrical point as your Arduino or other Microcontroller ground.
VCC: The is where you connect the high side of the voltage you are measuring
S: This connects to your Arduino or other Microcontroller analog input.
– (or minus): This connects to your Arduino or other Microcontroller ground.
+: This is not connected. It does absolutely nothing….
