Smart Energy Meter with CT Sensor & Grafana Dashboard
Monitor home AC power consumption in real-time using non-invasive current transformers and MQTT telemetry.
Project Overview
Learn how to safely measure mains AC current and voltage using SCT-013 non-invasive current transformers and publish telemetry to InfluxDB and Grafana.
What You Will Build
- Non-invasive AC power sampling circuit with bias voltage
- True RMS current calculation algorithm in C++
- MQTT publisher sending telemetry every 1 second
- Grafana live kilowatt-hour dashboard and cost calculator
