Powered by a stable 5V supply and featuring an on-board power indicator, it delivers a reliable 185mV/A analog output for seamless integration into professional and DIY electronics projects. ## Description The device consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage. Review: Nice and usefull - Ofset voltage is there so current is not 0.00 u need to eleminate this ofset Voltage in coding and if coding is good then its give accurate value 2.5 volt its ofset voltage good for both ac and dc , i test it in AC voltage with 200 watt blub with arduino and serial monitor and compare with electeical Enargy Meater with same 200 watt bulbs Review: Good product - Works great ## Features - The current sensor chips ACS712ELC-05B - Pin 5V power supply, on-board power indicator - The module can be measured plus or minus 30 amps, corresponding to the analog output of 185 mV or A - There is no the detection current through, the output voltage is VCC or 2 - PCB Board Size: 31 (mm) x13 (mm) ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Generic | | Manufacturer | Bombay Electronics | | Country of Origin | China | | Model number | ACS712 30A | | Number of Memory Sticks | 1 | | Item Weight | 400 g | | Product Dimensions | 7 x 5 x 5 cm; 400 g | | Item model number | ACS712 30A | | Item Height | 50 Millimeters | | Item Width | 50 Millimeters | | Voltage | 5 Volts | | Included Components | 1 x ACS712 30A Hall Current Sensor Module | | Are batteries included? | No | ## Images ![ACS712 30A Hall Current Sensor Module - Image 1](https://m.media-amazon.com/images/I/41e9p6syDxL.jpg) ![ACS712 30A Hall Current Sensor Module - Image 2](https://m.media-amazon.com/images/I/313mA9wm1WL.jpg) ## Questions & Answers **Q: how can we distinguish between acs712 for 20A and 30A. Is there any labeling on the sensor module to know whether it is 20A or 30A type?** A: Hi,The ACS712 device comes in three variants, providing current range of±5A (ACS712-05B), ±20A (ACS712-20B), and ±30A (ACS712-30A). The ACS712-05B can measure current up to ±5A and provides output sensitivity of 185mV/A (at +5V power supply), which means for every 1A increase in the current through the conduction terminals in positive direction, the output voltage also rises by 185 mV. The sensitivities of 20A and 30A versions are 100 mV/A and 66 mV/A, respectively.To read these numbers you would require a good magnifying glass though :). **Q: Is it possible to measure Earth Leakage Current with it ?** A: Yes .. We can measure the earth leakage current.. It's possible **Q: it is compatible with arduino uno ?** A: For very slow speed it is OK. but for high speeds we have to use other platform like Raspberry Pi. **Q: Can i directly connect it 230 v supply** A: Yes you can connect it to 230v supply but maximum current should not be as it's specifications like 30A,20A,5A ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice and usefull *by N***Y on 16 August 2019* Ofset voltage is there so current is not 0.00 u need to eleminate this ofset Voltage in coding and if coding is good then its give accurate value 2.5 volt its ofset voltage good for both ac and dc , i test it in AC voltage with 200 watt blub with arduino and serial monitor and compare with electeical Enargy Meater with same 200 watt bulbs ### ⭐⭐⭐⭐⭐ Good product *by A***R on 8 November 2019* Works great ### ⭐⭐⭐⭐ Nice products *by S***N on 22 July 2021* Woking fine. But calibration is needed. ## Frequently Bought Together - Generic ACS712 30A Hall Current Sensor Module - Robocraze ZMPT101B Single Phase Voltage Sensor | Voltage Transformer Module compatible with Arduino - (Pack of 1) - ApTechDeals Breadboard 840 point with jumper wires Set(10+10+10) --- ## 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.com.pa/products/64761074-acs712-30a-hall-current-sensor-module](https://www.desertcart.com.pa/products/64761074-acs712-30a-hall-current-sensor-module) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-05-19*
