Connect any sensor, understand any reading

Bloomit is a general-purpose IoT platform: your ESP32, Arduino or any board that speaks HTTP posts readings to a REST API, and the panel turns them into history, trends and alerts. It works for your plants and for the rest of your IoT.

How the system works

Three parts. You only build the first one if you want to.

01
The device measures
A Bloomit device or your own board reads its sensors on whatever interval you set. Soil humidity, temperature, light, pH, TDS — whatever you wired up.
02
It sends to the API
One authenticated POST per reading, over WiFi or over USB serial from the browser. The device token never expires, so the board runs unattended.
03
The panel explains it
Readings become history, trends and alerts. Assign a plant species and Bloomit also interprets the numbers against what that plant needs.

What people build with it

Plants and vegetable gardens

Soil humidity, watering and health per species. The most polished case: Bloomit reads the values against what that plant actually needs.

Greenhouses and indoor grows

Temperature, air humidity and light across several points, with alerts when something drifts out of range.

Hydroponics and aquariums

Water pH, TDS and temperature, with enough history to catch the drift before it becomes a problem.

Rooms, racks and labs

Any magnitude you can measure and want to watch over time, plants or not: a server room, a fermentation chamber, a workshop.

University projects

The infrastructure is already there, so the work goes into firmware and the report instead of standing up a backend.

Your own hardware

If your board can do an HTTP POST it is already compatible. No vendor lock-in, no particular language required.

What it can measure

Nine sensor types are supported out of the box, each with its own unit and health thresholds. Need one that is not here? It can be added.

What you get

Readable history

Every reading is stored and charted, so a slow drift is visible days before it becomes a failure.

Species-aware insights

For plants, the same 40% soil humidity is fine for a cactus and an emergency for a fern. Bloomit knows the difference.

Alerts when it matters

Notifications when a value leaves the healthy range set for that device.

A REST API, not a framework

No broker, no SDK, no certificates to rotate. If your board can do an HTTP POST, it can talk to Bloomit.

USB serial fallback

No WiFi on your board? Plug it in and the browser forwards the serial output using the Web Serial API.

Tokens that survive reboots

This is the whole integration

One POST with a bearer token. Same endpoint from an ESP32, a Raspberry Pi or a curl in your terminal.

curl -X POST https://device.api.bloomit.app/sense \
  -H "Authorization: Bearer <device_token>" \
  -H "Content-Type: application/json" \
  -d '{ "sensorType": 1, "value": 42.5 }'
