Raspberry Pi × Custom HAT × 3D Enclosure × Cloud Integration

Are You Facing These Challenges?

Manual sensor checks
Late detection of abnormal conditions
No historical data logging
Off-the-shelf systems are too rigid or too expensive
You need a small-batch custom solution

We design and build right-sized IoT systems tailored to your needs.

🔎 Project Overview

We developed a fully integrated IoT monitoring system using:

Raspberry Pi with touchscreen UI
Multiple environmental sensors
Local LED and audio alerts
Remote status notification via M5 ATOM (ESP32)
Automatic Google Spreadsheet data logging
Custom-designed HAT PCB
Custom 3D printed enclosures

From concept to assembly — fully handled.

🖥 Local Touchscreen Dashboard

Real-time data display
Color-coded status indicators
Touch-based operation
Standalone operation (no server required)

🚨Real-Time Alert System

Green: Normal
Yellow: Warning
Red: Critical
Audio alerts for immediate attention

Remote notification via M5 ATOM (ESP32) device:

LED color changes remotely
Ideal for offices, control rooms, or separate facilities

☁ Automatic Cloud Logging

Data automatically sent to Google Sheets
Timestamped entries
CSV export ready
No dedicated server required

Perfect for:

Compliance documentation
Research data collection
Environmental tracking
Small industrial monitoring
