Voltage Detection Sensor Module 25V

<p>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.</p> <p>For example with a 0-5V analog input range, you are able to measure a voltage up to 25V. This voltage sensor module also includes convenient screw terminals for easy and secure connection of a wire.</p> <p><strong>This module is based on the principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller. <a href=""https://robu.in/product-category/arduino-2/arduino/"" target=""_blank"" rel=""noopener noreferrer"">Arduino</a> 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).</strong></p> <p>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.</p> <h5><strong>Note:</strong></h5> <p><em>Keep in mind, you are restricted to voltages that are less than 25 volts.   More than that and you will exceed the voltage limit of your Arduino input.</em></p> <h5><strong>Connection Diagram</strong></h5> <h5><a href=""https://robu.in/wp-content/uploads/2017/05/robu-1.png""><img class=""wp-image-55686 aligncenter"" title=""Voltage Detection Sensor Module 25V, Voltage Detection Sensor Module, Voltage Sensor Module Robu 1"" src=""https://robu.in/wp-content/uploads/2017/05/robu-1-300×122.png"" alt=""Https://Drive.google.com/File/D/1Hc4Si8Fuj0B-Frduwbvkmhmlw_W4Pwlv/View?Usp=Sharing"" width=""529"" height=""215"" loading=""lazy"" /></a></h5> <hr /> <h4><strong>Features :</strong></h4> <ol> <li><strong>Output Interface:</strong> “+ ” connected 5/3.3V, “-” connected GND, “s” connected Arduino AD pins</li> <li><strong>DC input interface:</strong> red terminal positive with VCC, negative with GND</li> <li>You can also use the IICLCD1602 LCD to display voltage.</li> <li>By 3P connector, connect this module with the expansion of board Arduino, not only makes it easier for you to detect voltage battery.</li> </ol> <hr /> <h4><strong>Package Includes :</strong></h4> <p>1×Voltage Detection Sensor Module</p>
