Spark, A Unified IoT Platform for Custom Devices

NovaCept Logo

Since 2001, Project Spark has been NerdHerd’s flagship initiative for designing, building, and operating custom IoT devices that power real-world innovation. From smart sensors and consumer gadgets to complex industrial equipment, Project Spark provides a single, unified software platform that seamlessly connects hardware with the cloud. Over the years, it has evolved into a robust ecosystem where devices communicate reliably, data flows securely, and businesses can scale without technical limitations. By combining decades of engineering expertise with modern IoT standards, Project Spark continues to enable organizations to unlock automation, optimize operations, and bring new ideas to life.

What Project Spark Does

Spark brings embedded firmware, secure connectivity, cloud APIs, and fleet operations together so you can ship hardware fast and run it reliably at scale.

Design & deliver custom devices.
Connect securely to the cloud.
Operate fleets with OTA updates.
Automate & integrate using APIs.
Analyze & predict with built-in AI.

Core Capabilities

Embedded & Edge
  • Reference firmware for ESP32/STM32/Raspberry Pi/Linux.
  • Drivers for sensors/actuators; offline buffering; local rules.
  • Edge AI options (tinyML/computer vision) for on-device detection.
MQTT/HTTP/CoAP out of the box; adapters for Modbus, CAN, OPC-UA, BACnet, BLE, Zigbee, LoRaWAN. Smart backoff, QoS, and payload compression for low-bandwidth links.
  • Device registry & provisioning.
  • Digital twin model for safe remote control.
  • Rules engine & workflows (if/then, schedules, geofence).
  • Data pipelines to data lakes/warehouses.
  • Dashboards & alerts for telemetry and health.
  • mTLS, rotating certs/keys, optional secure elements/TPM support.
  • RBAC with fine-grained scopes.
  • Signed OTA firmware with rollout rings and instant rollback.
  • Full audit trails for config, commands, and access.
  • SDKs (C/C++, Python, JS/TS) + Postman collections and OpenAPI.
  • CI/CD for firmware builds; BOM & version tracking for hardware variants.
  • Simulators and golden-device tests for stable releases.
  • One platform from hardware to cloud—no fragile glue code.
  • Modular & future-proof: add devices or analytics without re-platforming.
  • Operate at scale: safe OTA, observability, and fleet health baked in.
  • Faster time-to-market: reference designs, SDKs, and proven playbooks.
