IoT Development
IoT Solutions for Connected Devices and Data
QASTCO builds IoT development projects from sensor to screen. We write device firmware, design cloud platforms, and create real-time dashboards that turn raw data into decisions.
Our IoT solutions cover industrial monitoring, smart buildings, asset tracking, and healthcare devices. You own the hardware design files, firmware source, and cloud infrastructure.

IoT Development Services from Prototype to Scale
Firmware, cloud, dashboards, and analytics in one team.
Device Firmware
C/C++ firmware for microcontrollers with OTA update support. BLE, Wi-Fi, LoRa, and cellular connectivity.
Cloud Platform
AWS IoT Core or Azure IoT Hub with MQTT ingestion, device shadow, and auto-scaling.
Real-Time Dashboards
Grafana or custom React dashboards. Live data, historical trends, and configurable alert thresholds.
Data Analytics
Time-series analysis, anomaly detection, and predictive models trained on your operational data.
Security & Compliance
TLS encryption, X.509 certificates, and device identity management. GDPR-ready data handling.
Edge Computing
On-device processing for latency-critical tasks. Reduce cloud costs and work offline when needed.
Our IoT Development Process
Hardware prototyping, cloud setup, and dashboards in parallel sprints.
Prototype & Validate
We select components, build a working prototype, and validate data transmission in your real environment.
Develop & Integrate
Firmware, cloud ingestion, and dashboards developed in parallel. You see live data within the first sprint.
Deploy & Scale
Pilot deployment, stress testing, then rollout to full fleet. OTA firmware updates keep devices current.
IoT Development FAQs
IoT projects vary widely. A proof-of-concept with a handful of sensors and a basic dashboard starts from £8,000. Production-ready systems with custom firmware, cloud infrastructure, and mobile apps typically range from £25,000 to £80,000 depending on scale.
Yes, and we recommend it. We build functional prototypes in 4 to 6 weeks using off-the-shelf hardware like Raspberry Pi or Arduino. This lets you validate the concept, test sensor accuracy, and gather feedback before committing to a production build.
We work with Wi-Fi, Bluetooth Low Energy (BLE), LoRaWAN, cellular (4G/5G), and Zigbee. The right choice depends on your range requirements, power constraints, and data volume. We advise on the best option during the discovery phase.
We use end-to-end encryption for data in transit, secure device authentication with unique certificates, firmware signing to prevent tampering, and role-based access control on dashboards. All data storage complies with UK GDPR requirements.
Edge processing (on the device) is best for real-time responses and reducing bandwidth costs. Cloud processing suits data aggregation, historical analysis, and machine learning. Most IoT systems use a combination of both, and we design the split based on your latency and cost priorities.
