Remote environmental monitoring
Sites where a manual reading is being replaced with automated telemetry.
IoT Product Development
Complete IoT products combining custom hardware, embedded firmware, cloud connectivity and a mobile or web dashboard.
Overview
What this service covers
We take an IoT product from requirements through hardware, firmware, cloud connectivity and the dashboard a user or operator actually looks at. Because hardware, firmware and app development happen under one team, the device-to-dashboard data path is designed as one system instead of three separately-built pieces that have to be reconciled later.
Client Problems
Problems this service solves
- An idea for a connected product exists but there's no hardware, firmware or app team to build it.
- An existing device has no cloud connectivity or dashboard.
- A site is monitored by manual visits instead of remote alerts.
- A single working prototype needs to become a small, repeatable production batch.
Capabilities
What we do
- End-to-end architecture: device, cloud and app
- MQTT and REST API integration
- Sensor and actuator integration
- Remote monitoring and alerting
- OTA firmware updates
- Mobile or web dashboard integration
Technologies
Tools & platforms
ESP32 or STM32 hardware, MQTT/HTTP APIs, Firebase-style cloud backends, and Flutter for the companion mobile app where one is in scope.

Development Process
How we approach an IoT project
- 01Requirements & architecture
Map the device, cloud and app pieces before writing any code.
- 02Hardware & firmware
Build and validate the device side first.
- 03Cloud & app integration
Connect telemetry to a dashboard or app.
- 04Field testing & handoff
Validate the full device-to-dashboard path before delivery.
Deliverables
What you receive
- Hardware design files (where hardware is built)
- Firmware source code
- API / integration documentation
- Mobile or web dashboard, per project scope
Testing & Validation
How the device-to-dashboard path gets validated
The device side is bench-tested first — sensor readings, power behaviour and OTA update/rollback — before any cloud or app work depends on it. Once connected, telemetry is validated end to end: a sensor reading reaching the dashboard accurately and promptly, reconnect behaviour after a dropped connection, and alerting firing when it's supposed to. Field testing happens against the actual deployment environment, not just a bench Wi-Fi network, since that's usually where a system's real weak points show up.
Applications
Where this is used

How We Can Help
How PAK-EL LAB Can Help
If you have an idea for a connected product — or an existing device that needs cloud connectivity, a dashboard, or production-readiness — we can take on the hardware, firmware, cloud and app together, or just the piece you're missing. Scope, deliverables, schedule and quotation are confirmed once we understand what the device needs to sense, send and show, and the environment it has to work in. We work with clients internationally and collaborate remotely as standard practice.

FAQ
Frequently Asked Questions
Do you build the hardware too, or only the software side?
Either. We can design custom hardware from scratch, or build firmware, cloud and app around hardware you already have.
What happens if site connectivity is unreliable?
We can design around LoRa/RF or local data logging instead of assuming constant Wi-Fi/cellular — this gets scoped during the architecture stage, not discovered after deployment.
Can an existing prototype be turned into a production-ready product?
Yes, taking a working prototype through firmware hardening, enclosure design and small-batch manufacturing prep is common work.
Do you build the mobile app and the cloud backend as well?
Yes, when they're in scope — Flutter for the app, and a Firebase-style backend for data and authentication, designed alongside the device firmware rather than bolted on afterward.
