SensorFlow by Gremantek · IoT monitoring platform

Beta · Built with early users

Monitor your sensors.
All in one place.

Connect ESP32, Raspberry Pi, Wi-Fi-capable Arduino projects, and other sensor hardware to SensorFlow for live monitoring, alerts, device status, and historical data — without building your own monitoring backend.

Works with ESP32, Raspberry Pi, Wi-Fi-capable Arduino projects, and other HTTPS-capable devices.

How it works

Connect. Monitor. Respond.

  1. 01

    Connect your hardware

    Create a SensorFlow device and connect supported hardware using the existing ingestion API.

  2. 02

    Monitor your data

    See current readings, device status, and historical trends from one dashboard.

  3. 03

    Respond to changes

    Use thresholds and alerts to know when monitored conditions need attention.

See your sensor data clearly

SensorFlow turns incoming readings into a dashboard you can actually understand.

What you get

Live monitoring

See the latest readings and device status.

Alerts

Know when monitored values leave their configured range.

Historical trends

Review changes over time instead of watching raw serial output.

No monitoring backend to build

SensorFlow handles the dashboard, history, alerts, and device-monitoring layer.

  • “SensorFlow is really easy to set up and use. I like how the dashboard makes it simple to monitor sensor data, see alerts, and check historical readings without needing a complicated setup. The hardware connection process is straightforward, and the interface feels clean and organized. It’s especially useful for small IoT projects where you want to get sensor data online quickly. I’m excited to see how the platform continues to improve.”
