This voltage transformer module allows microcontrollers to safely detect and measure AC voltage signals, making it ideal for developing smart energy monitoring and electrical measurement systems. Featuring an onboard precision miniature voltage transformer, the ZMPT101B provides electrical isolation while converting high-voltage AC signals into measurable analog outputs. The integrated high-precision operational amplifier circuit improves signal accuracy by performing sampling and compensation functions for stable measurement results. The module can measure AC voltage levels up to 250V and provides an adjustable analog output signal that can be calibrated according to application requirements. Its sine wave output with a DC component of approximately half the supply voltage (1/2 VCC) allows easy processing by Arduino and other microcontroller-based systems. The ZMPT101B voltage sensor is widely used in energy monitoring devices, smart power systems, AC voltage detection projects, IoT electrical monitoring and DIY electronics applications. Its compact design, reliable performance and simple analog interface make it an excellent choice for students, engineers and hobbyists working on power measurement and automation projects. ## 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 | #19,306 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #603 in Robotic Kits & Accessories | | Brand Name | Robocraze | | Customer Reviews | 4.1 4.1 out of 5 stars (61) 4.1 out of 5 stars | | Importer Contact Information | Robocraze, Ground Floor, 912/10 Survey no. 104 4th G street, Chelekare, Kalyan Nagar, Bengaluru - 560043, Contact: +91 812 3057 137 | | Item Type Name | Robocraze AC Voltage Sensor Module ZMPT101B | | Item Weight | 50 Grams | | Manufacturer | Robocraze | | Model Number | RC-A-525 | | Mounting Type | PCB Mount | | Packer Contact Information | 8123057137 | | Part Number | RC-A-525 | | 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 AC Voltage Sensor Module ZMPT101B Single Phase Voltage Transformer | 250V AC Voltage Detection Sensor with Precision Op Amp Circuit | Analog Output Module Compatible with Arduino IoT - Image 1](https://m.media-amazon.com/images/I/51JTat0GZ7L.jpg) ![Robocraze AC Voltage Sensor Module ZMPT101B Single Phase Voltage Transformer | 250V AC Voltage Detection Sensor with Precision Op Amp Circuit | Analog Output Module Compatible with Arduino IoT - Image 2](https://m.media-amazon.com/images/I/51AtaDlQVPL.jpg) ![Robocraze AC Voltage Sensor Module ZMPT101B Single Phase Voltage Transformer | 250V AC Voltage Detection Sensor with Precision Op Amp Circuit | Analog Output Module Compatible with Arduino IoT - Image 3](https://m.media-amazon.com/images/I/61cPFfMVdDL.jpg) ![Robocraze AC Voltage Sensor Module ZMPT101B Single Phase Voltage Transformer | 250V AC Voltage Detection Sensor with Precision Op Amp Circuit | Analog Output Module Compatible with Arduino IoT - Image 4](https://m.media-amazon.com/images/I/51Ksa9WwnqL.jpg) ![Robocraze AC Voltage Sensor Module ZMPT101B Single Phase Voltage Transformer | 250V AC Voltage Detection Sensor with Precision Op Amp Circuit | Analog Output Module Compatible with Arduino IoT - Image 5](https://m.media-amazon.com/images/I/511uuLB524L.jpg) ## Available Options This product comes in different **Item Package Quantity** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product... Accuracy was 98.78% *by on Reviewed in India 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 on Reviewed in India 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 on Reviewed in India 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.ni/products/77092843-robocraze-ac-voltage-sensor-module-zmpt101b-single-phase-voltage-transformer](https://www.desertcart.ni/products/77092843-robocraze-ac-voltage-sensor-module-zmpt101b-single-phase-voltage-transformer) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-07-16*
