Hardware we build and run
ESP32-based IoT devices, designed and provisioned in-house. Every unit runs on our secure MQTT cloud and updates over the air — for life.
The hardware running today
These are the devices we currently manufacture and deploy. Each one is field-tested, OTA-updatable, and built to run unattended for years.
Clock · Notice board · Timer · StopwatchSmart Display Clock
An ESP32-powered wall display that shows synchronized time by default and transforms into a notice board, countdown timer, or stopwatch on command — all controlled from the web dashboard.

| Connectivity | WiFi 2.4GHz + MQTT (TLS) |
| Display | LED panel (single or double) |
| Modes | 5 — clock, notice, timer, random, stopwatch |
| Scenes | 6 presets (scene0–scene5) |
| Updates | OTA firmware via MQTT |
- Scheduled notices with start/end times
- Countdown timers & stopwatches
- Single or double-panel configs
- Scene presets per room
RFID card reader · Real-time cloud syncAttendance Terminal
A wall-mounted terminal where a single tap of an RFID card securely records a student or staff member's presence and streams the event to the dashboard in real time — no manual roll-call, no paperwork.
| Microcontroller | ESP32 |
| Reader | RFID / NFC card reader |
| Connectivity | WiFi 2.4GHz + MQTT (TLS) |
| Sync | Real-time (QoS 1, guaranteed) |
