If you are planning measure Voltage just buy with no reason. It works awesome l. I loving it. Review: Gives me actual 230v AC - Gives me 230v ac cycle in Arduino with respect to time but we can't find True RMS in power so be careful in buying ## Features - The AC voltage sensor can detect an electric field, most of the detection can be done by a simple capacitor - Onboard precision miniature voltage transformer - On-board high-precision op amp circuit, which performs functions such as accurate sampling and proper compensation of signals - The module can measure AC voltage within 250V, and the corresponding output analog can be adjusted - Sine wave, the middle value (DC component) of the waveform is 1/2VCC ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076Q9DP8W | | Best Sellers Rank | #5,977 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #134 in Robotic Kits & Accessories | | Brand | Robocraze | | Brand Name | Robocraze | | Country of Origin | China | | Customer Reviews | 4.1 out of 5 stars 61 Reviews | | Item Weight | 50 Grams | | Manufacturer | Robocraze | | Model Number | RC-A-525 | | Mounting Type | PCB Mount | | Number of Items | 1 | | Number of Packs | 1 | | Packer Contact Information | 8123057137 | | Part Number | RC-A-525 | | Power Source | AC mains | | Power Source Type | AC mains | | Unit Count | 1 Count | ## Product Details - **Brand:** Robocraze - **Power Source:** AC mains - **Mounting Type:** PCB Mount - **Item Weight:** 50 Grams - **Manufacturer:** Robocraze ## Images ![Robocraze ZMPT101B Single Phase Voltage Sensor | Voltage Transformer Module compatible with Arduino - (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/51JTat0GZ7L.jpg) ![Robocraze ZMPT101B Single Phase Voltage Sensor | Voltage Transformer Module compatible with Arduino - (Pack of 1) - Image 2](https://m.media-amazon.com/images/I/51AtaDlQVPL.jpg) ![Robocraze ZMPT101B Single Phase Voltage Sensor | Voltage Transformer Module compatible with Arduino - (Pack of 1) - Image 3](https://m.media-amazon.com/images/I/61cPFfMVdDL.jpg) ![Robocraze ZMPT101B Single Phase Voltage Sensor | Voltage Transformer Module compatible with Arduino - (Pack of 1) - Image 4](https://m.media-amazon.com/images/I/51Ksa9WwnqL.jpg) ![Robocraze ZMPT101B Single Phase Voltage Sensor | Voltage Transformer Module compatible with Arduino - (Pack of 1) - Image 5](https://m.media-amazon.com/images/I/71PQJ+zVmiL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product... Accuracy was 98.78% *by D***D on 19 December 2018* Excellent Accuracy !. If you are planning measure Voltage just buy with no reason. It works awesome l. I loving it. ### ⭐⭐⭐⭐ Gives me actual 230v AC *by V***N on 13 April 2022* Gives me 230v ac cycle in Arduino with respect to time but we can't find True RMS in power so be careful in buying ### ⭐ Not working faulty product. *by A***R on 4 June 2019* I have bought two modules and both are faulty.Do not buy this item. Op-amp ic is completely different from what its supposed to be. Pins of the op amp are different so its not supposed to work. And it took more than two weeks to troubleshoot the problem and I cant even return now. I have two of the module lying around which is faulty. ## Frequently Bought Together - Robocraze ZMPT101B Single Phase Voltage Sensor | Voltage Transformer Module compatible with Arduino - (Pack of 1) - Robodo MO11 Acs712 30A Range Current Sensor Module or Hall Sensor - Aptechdeals Jumper Wires Male To Male, Male To Female, Female To Female/ Breadboard Jumper Wires (40+40+40) --- ## 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.vu/products/77092843-robocraze-zmpt101b-single-phase-voltage-sensor-voltage-transformer-module-compatible](https://www.desertcart.vu/products/77092843-robocraze-zmpt101b-single-phase-voltage-sensor-voltage-transformer-module-compatible) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-16*
