Time Series Anomaly Detection MQTT Alert Kit with ESP32 + LED
Time Series Anomaly Detection MQTT Alert Kit with ESP32 + LED — Industrial-Grade Condition Monitoring
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 puts a real-time anomaly detection system on your workbench. Using dual INA219 and ACS712 current sensors, the ESP32 continuously reads current draws, applies Statistical Process Control (SPC) algorithms locally, and fires an MQTT alert the moment a value violates predefined limits. It is purpose-built for engineers prototyping predictive maintenance on motors, pumps, or any DC‑powered machinery where unexpected current shifts signal trouble.
What You'll Build
You will assemble a self-contained current monitor that logs every reading with an RTC timestamp to a MicroSD card, shows live Xbar‑R trends on the 0.96‑inch OLED, and publishes anomaly alerts to any MQTT broker. The enclosure makes it ready for bench‑top demonstration or long‑term field tests, giving you a polished prototype of an Industry 4.0 predictive maintenance node.
What You'll Learn
- Implement Statistical Process Control (Xbar‑R charts) directly on an embedded microcontroller
- Interface I2C sensors (INA219) and analog current sensors (ACS712) with ESP32
- Build an MQTT publish‑subscribe alert pipeline from device to dashboard or mobile
- Use DS3231 RTC for accurate timestamping and MicroSD for structured data logging
- Calibrate current sensors and design a noise‑free power stage with buck converter and decoupling capacitors

Who This Kit Is For
This advanced project targets final‑year B.Tech (ECE/EEE) students who need an impactful working model, Smart India Hackathon teams tackling industrial IoT challenges, and R&D engineers prototyping condition‑monitoring systems. The deep dive into SPC and MQTT also fits M.Tech coursework at IIT, NIT, VIT, or BITS, where real‑time embedded analytics are essential.
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?
Open the AI companion via the QR code or reach out on WhatsApp — our support team can see logs from the AI session and help you over a specific soldering or calibration hurdle.
Can I adjust the anomaly detection algorithm?
Absolutely. The ESP32 firmware is fully open; you can modify control limits, add Western Electric rules, or even swap SPC for a moving average filter to suit your application.
Is prior MQTT experience required?
Basic familiarity helps, but the AI companion walks you through setting up a local Mosquitto broker (or a free cloud MQTT service) and testing the alert flow.
Can I monitor AC mains current with this kit?
The kit is designed for low‑voltage DC current monitoring. While the ACS712 provides galvanic isolation, measuring mains AC requires additional safety measures and is not a recommended first step.
ESP32 processes INA219 current readings locally. Statistical process control flags anomalies and alerts via MQTT.
