It offers non-invasive measurement up to 100V and ±100A DC, with real-time Watt-hour and Ampere-hour tracking. Featuring UART serial communication and Modbus compatibility, it integrates easily into control and monitoring systems. Its adjustable over-current detection and zero-current calibration make it a reliable choice for applications like electric vehicles, solar systems, and battery management—all proudly made in India. ## Description VVM302 Voltage Current Energy Sensor Module provides economical and precise voltage and current measurement solution for industrial and commercial applications. It allows system designers to monitor any current path without breaking or changing original system. Current flowing through the 9.0mm sensor slot will generate a magnetic field which is sensed and converted into a proportional voltage. The system uses precision resistors for DC voltage measurement and WCS1600 Hall Effect Sensor for current measurement. Diameter 9.0mm conductor through hole, Current Measurement Electrical Isolation 4000V Over current value can be easily set using potentiometer Bandwidth > 20kHz, nearly zero magnetic hysteresis Push button switch to toggle modes between DC Voltage Current, Watt hour and Ampere hour, over-current values and calibration setting Over Current can be detected by adjusting the preset RV1 for desired value of current.Zero Current Calibration Mode allows the user to reset the current reading to zero when there is no current flowing through the device. V, I, Wh and Ah values are available on Tx pin of Serial port Energy Wh and Ah values are auto savedDefault Baud rate can be changed by sending character 'B' through the Serial pin. To maintain accuracy, use a good quality power supply with minimum voltage drift. The device can be configured as a Modbus slave using a TTL to RS485 converter. Modbus Registers 40001 - 40008NOTE: Current measurement accuracy will be less for very low current values. ## Features - Hall Effect based non-invasive current measurement, no shunt resistor or wire break required, based on WCS1600 sensor, precision voltage measurement - DC voltage: 100V, DC current range: +/- 100A, Energy and Battery Capacity measurement in Wh and Ah with auto save - Measured value can be fed to any micro-controller or Data Acquisition System,, Data is also available on Serial port, Default Baud Rate 9600, programmable, - Current Measurement Sensitivity is 22mV/A, Voltage Measurement Sensitivity is 25mV/V, Diameter 9.0mm conductor through hole for current measurement, can be configured as Modbus Slave RTU via TTL RS485 Converter, Default Slave ID 1, programmable - Typical Applications include Test and Measurement Systems, Instrumentation and Control Systems, Motor Control, Power Systems, Solar Systems, Battery Chargers, Electric Vehicles, battery capacity estimation, Load Detection, Over-Current Fault Detection, etc MADE IN INDIA. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Vajravegha Mobility | | Manufacturer | Vajravegha Mobility Pvt Ltd | | Number of Memory Sticks | 1 | | Item part number | VVM302 | | Voltage | 100 Volts | ## Images ![Vajravegha Voltage Current Energy Sensor Module 100V 100A DC with Watt hour Ampere hour Serial UART Communication Over Current Detection MODBUS Compatible No Shunt Required - Image 1](https://m.media-amazon.com/images/I/71H8LkSQXtL.jpg) ![Vajravegha Voltage Current Energy Sensor Module 100V 100A DC with Watt hour Ampere hour Serial UART Communication Over Current Detection MODBUS Compatible No Shunt Required - Image 2](https://m.media-amazon.com/images/I/71t4sTusJrL.jpg) ![Vajravegha Voltage Current Energy Sensor Module 100V 100A DC with Watt hour Ampere hour Serial UART Communication Over Current Detection MODBUS Compatible No Shunt Required - Image 3](https://m.media-amazon.com/images/I/51+QGDlGFTL.jpg) ![Vajravegha Voltage Current Energy Sensor Module 100V 100A DC with Watt hour Ampere hour Serial UART Communication Over Current Detection MODBUS Compatible No Shunt Required - Image 4](https://m.media-amazon.com/images/I/81UNRL5SaBL.jpg) ![Vajravegha Voltage Current Energy Sensor Module 100V 100A DC with Watt hour Ampere hour Serial UART Communication Over Current Detection MODBUS Compatible No Shunt Required - Image 5](https://m.media-amazon.com/images/I/51Yx5Rl7iuL.jpg) ## Frequently Bought Together - Vajravegha Voltage Current Energy Sensor Module 100V 100A DC with Watt hour Ampere hour Serial UART Communication Over Current Detection MODBUS Compatible No Shunt Required - ApTechDeals Jumper Wires Male to Male, Male to Female, Female to Female/breadboard jumper wires (40+40+40) - DHT11 Temperature and Humidity Sensor Module for Arduino Raspberry Pi --- ## 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.ae/products/340492306-vajravegha-voltage-current-energy-sensor-module-100v-100a-dc-watt](https://www.desertcart.ae/products/340492306-vajravegha-voltage-current-energy-sensor-module-100v-100a-dc-watt) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-08*
