Designed around a resistive divider, it safely scales voltage inputs 5 times down for Arduino and Raspberry Pi compatibility. Sold in packs of 10, it’s perfect for developers and makers needing reliable, sensitive voltage detection with professional support. ## Description Description: This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, for 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 for 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. Specification: Voltage input range: DC0-25V Voltage detection range: DC0.02445V-25V Voltage Analog Resolution: 0.00489V DC input connector: Terminal cathode connected to VCC, GND negative pole Output interface: + 5V or 3.3V - GND S for Arduino AD pins Package included: 10 X Voltage Sensor Review: Divide by 5 Voltage divider modules. - These are actually Divide By 5 Voltage Dividers consisting of 30K and 7.5K resistors. Accuracy is fair, about 1% and good enough for most applications. I am using them to scale down 50 watt solar panel voltages to within the 0-5 volt range of the Arduino Pro Mini's A/D inputs and they work good. Connections to the modules are a little strange but not a problem. For future projects though I will use individual 0.1% 30k and 7.5k resistors which I found recently at very good prices. Review: Raspberry pi voltage reading - Works good. Slight varience in readings. Using with mcp3008 for reading voltage on raspberry pi. If you use this with raspberry pi make sure to use 3.3v to not burn out your gpio. And to stabalize readings pull multiple times and average reading. Adafruit mcp3008 tutorial works perfect. ## Features - This voltage tester module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times. - The voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V - Voltage input range: DC 0 - 25 V, Voltage Analog Resolution: 0.00489V - You can use it for Raspberry Pi via ADC but for need for programmatical corrections. - DC input connector: Terminal cathode connected to VCC, GND negative pole .If you have any issue when using our product,or you need product use documentation， please contact us directly for assistance.we will reply your problem in 24 hours.We try our best to provide the most professional service for each customer. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FVVSYYH | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #420,900 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #318 in Robot Parts | | Customer Reviews | 4.2 4.2 out of 5 stars (60) | | Date First Available | July 24, 2018 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.76 ounces | | Manufacturer | Geekstory | | Material | ABS | | Package Dimensions | 6.42 x 4.25 x 1.22 inches | | Part Number | GR0430X10 | ## Images ![Voltage Tester Sensor Measurement Detection Module DC 0-25V Terminal Sensor Module for Arduino UNO Mega Robot Smart Car Geekstory (Pack of 10) - Image 1](https://m.media-amazon.com/images/I/61SCl6cnOCL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Divide by 5 Voltage divider modules. *by S***S on November 23, 2019* These are actually Divide By 5 Voltage Dividers consisting of 30K and 7.5K resistors.
