Designed for Arduino and Raspberry Pi platforms, it safely scales input voltage by 5x for accurate readings. This pack of 10 modules is perfect for engineers, makers, and educators seeking reliable, scalable voltage measurement tools with professional-grade performance and easy terminal connectivity. ## 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 ## 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 | #488,864 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #536 in Robot Parts | | Customer Reviews | 4.3 4.3 out of 5 stars (61) | | 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) ![Voltage Tester Sensor Measurement Detection Module DC 0-25V Terminal Sensor Module for Arduino UNO Mega Robot Smart Car Geekstory (Pack of 10) - Image 2](https://m.media-amazon.com/images/I/613e3QWA87L.jpg) ![Voltage Tester Sensor Measurement Detection Module DC 0-25V Terminal Sensor Module for Arduino UNO Mega Robot Smart Car Geekstory (Pack of 10) - Image 3](https://m.media-amazon.com/images/I/71+Z4M6-pLL.jpg) ![Voltage Tester Sensor Measurement Detection Module DC 0-25V Terminal Sensor Module for Arduino UNO Mega Robot Smart Car Geekstory (Pack of 10) - Image 4](https://m.media-amazon.com/images/I/71YNkI9siaL.jpg) ![Voltage Tester Sensor Measurement Detection Module DC 0-25V Terminal Sensor Module for Arduino UNO Mega Robot Smart Car Geekstory (Pack of 10) - Image 5](https://m.media-amazon.com/images/I/61ong6Qk30L.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/82496402-voltage-tester-sensor-measurement-detection-module-dc-0-25v-terminal](https://www.desertcart.co.th/products/82496402-voltage-tester-sensor-measurement-detection-module-dc-0-25v-terminal) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-07-07*
