IoT Device Development
IoT Device Development
Builds secure connected devices that acquire sensor data and exchange approved telemetry with gateways, cloud platforms, and dashboards.
Quick Service Summary
- Parent Domain: Embedded Systems Design and Development Services
- Execution Model: Custom Engineering Scope
- Verification: Bench & Functional Testing
- Delivery Deliverables: Schematics, Code & Documentation
The Engineering Challenge
Connected devices frequently suffer from erratic wireless connectivity, excessive power drain, data loss during outages, and vulnerabilities in remote transmission.
The Desired Outcome
Production-ready IoT devices engineered with fail-safe local buffering, encrypted cloud telemetry, automatic reconnection routines, and low-power wireless profiles.
Core Technical Capabilities
Application-specific engineering focused on reliability, performance, and maintainability.
Wireless connectivity integration: Wi-Fi, BLE 5.x, LTE-M, NB-IoT, LoRaWAN
Local non-volatile buffering to prevent data loss during network disconnections
Encrypted communication using TLS 1.3, MQTT with mTLS, and HTTPS REST APIs
Battery management and solar harvesting power circuitry
Over-the-air (OTA) firmware upgrade mechanisms with rollback protection
Compact enclosure integration with ingress protection (IP65/IP67 considerations)
Technical Approach
We design the edge device to operate reliably under intermittent network conditions. Telemetry payloads are serialized into compact JSON or Protocol Buffers, cached locally in SPI Flash, and transmitted upon network restoration.
Required Customer Inputs
Required sensor measurements, transmission frequency, operating environment, available power source (battery vs mains), and target cloud backend platform.
Project Deliverables
- Complete electronic design package (schematic, layout, BOM)
- Validated device firmware with cloud connection client
- API payload specification and gateway mapping documentation
- Bench test reports validating RF link quality and power consumption
Scope Boundaries & Safety Safeguards
Cellular network SIM subscriptions and third-party cloud hosting fees are the responsibility of the customer. TC Smart Technology adheres to transparent engineering standards: solutions do not bypass machine safety interlocks, and all AI features retain human-in-the-loop governance.
