Automated Meter Reading Smart Grid Node
Automated Meter Reading Smart Grid Node Kit with Arduino Portenta C33
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you build a field-ready Automated Meter Reading (AMR) node that reads power, water, and gas meters simultaneously via pulse counters. The Arduino Portenta C33 securely signs every reading using its on-board hardware security module, then posts authenticated data directly to a utility API — exactly like the nodes deployed in India's smart city pilot projects.
What You'll Build
A fully enclosed DIN-rail mountable device that counts pulses from the PZEM-004T energy monitor and YF-S201 flow sensors, timestamps readings with a DS3231 RTC, and transmits them as signed JSON payloads over Wi-Fi or Ethernet. You’ll end up with a prototype that mirrors the communication architecture utilities use for tamper-proof billing automation.
What You'll Learn
- Interfacing pulse-output meters (energy, water, gas) with Arduino Portenta C33
- Using the on-board secure element to generate hardware-bound digital signatures for IoT data
- Posting authenticated sensor data to a cloud-based utility API via HTTPS
- Assembling and calibrating a multi-utility AMR node in a DIN-rail enclosure

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE final-year students working on smart grid or IoT security capstone projects, Smart India Hackathon teams building utility automation solutions, and professionals prototyping AMR nodes for utility pilot deployments. It’s equally relevant for researchers at IITs, NITs, and BITS Pilani exploring hardware-backed secure data transmission in smart city infrastructure.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Our AI companion covers wiring, code debugging, and API integration — you can also reach our Bengaluru team on WhatsApp for real-time guidance.
Can I adapt this for only electricity meters?
Yes, the code and carrier board are modular; you can omit flow sensors and just use PZEM-004T and ACS712 for power-only AMR.
Does the kit include the actual water and gas meters?
No, it includes flow sensors that attach to existing pulse-output meters. You can simulate pulses using the 100nF capacitor circuit included in the build guide.
How secure is the data signing?
The Arduino Portenta C33’s NXP SE050 secure element stores a private key that never leaves the chip. Signatures are ECC-based and verifiable by the utility server, meeting pilot-grade security for Indian smart meters.
C33 reads power + water + gas meters via pulse counters. Signs readings with hardware key and posts to utility API.
