IoT Stack Layer by Layer
- Device / Edge: ESP32 (Wi-Fi + BT, low cost consumer and light industrial), STM32 ARM Cortex-M (industrial-grade harsh environments, certifications), Raspberry Pi 4 (Linux SBC heavier compute, camera, USB peripherals). Sensors: DHT22/SHT31 (temp/humidity), BMP280 (pressure), INA219 (current/voltage), NEO-6M (GPS), ToF (distance).
- Connectivity: Wi-Fi (ESP32 802.11 b/g/n most facility IoT), Cellular (SIM7600 LTE modem remote or mobile assets), LoRaWAN (LPWAN very long range, very low power, very low bandwidth environmental sensors in remote areas), BLE (short-range, ultra-low power wearables, beacons), Ethernet (industrial reliable, no wireless interference).
- Protocol: MQTT (primary pub-sub, persistent connection, QoS 0/1/2, LWT for disconnect detection), HTTPS REST (simpler, good for low-frequency telemetry), CoAP (UDP-based for very constrained devices), AMQP (enterprise message bus integration).
- Cloud Platform: AWS IoT Core (managed MQTT broker, device registry, device shadow, rules engine integrates with Lambda/DynamoDB/S3/Kinesis/Timestream), AWS IoT Greengrass (edge computing Lambda functions and ML inference on device), Azure IoT Hub (alternative).
- Data Processing: AWS IoT Rules Engine (SQL-like topic rules route messages to Lambda/DynamoDB/S3/Kinesis), Amazon Timestream (purpose-built IoT time series database automatic tiering, fast aggregation queries), Apache Kafka (self-hosted).
- Dashboard / App: Grafana + Timestream (real-time charts, threshold alerts), custom React dashboard (device list, sensor history, alert history, geospatial map), mobile app (React Native field technician status checks, push alerts, manual device actions).
MQTT and AWS IoT Core
MQTT (Message Queuing Telemetry Transport) is a lightweight publish-subscribe messaging protocol designed for constrained devices and unreliable networks. A device publishes messages to a topic (e.g., devices/sensor-001/temperature) and any subscriber interested in that topic receives the message. MQTT advantages: tiny overhead (2-byte fixed header critical for cellular devices where data costs money), persistent TCP connections (no reconnection overhead per message), QoS levels (guarantee delivery at-most-once, at-least-once, or exactly-once based on criticality), last will and testament (the broker delivers a predefined message when a device disconnects unexpectedly automatic offline detection), and AWS IoT Core as a managed MQTT broker that scales to billions of messages without infrastructure management.
IoT Development Services We Deliver
ClickMasters operates as a full-stack iot development partner. Our team handles every layer of the software delivery lifecycle — product strategy, UI/UX design, backend engineering, cloud infrastructure, QA, and ongoing support.
Device Firmware
C/C++ or MicroPython firmware for microcontrollers: sensor drivers (DHT22 temperature/humidity, BMP280 pressure, INA219 current/voltage, GPS, ToF distance), network stack (Wi-Fi, cellular, LoRaWAN, BLE), MQTT/HTTPS communication, OTA client (A/B partition rollback), watchdog timers, sleep mode management (battery optimisation).
AWS IoT Core Backend
Managed AWS IoT Core infrastructure: device registry (device metadata, authentication methods), MQTT broker (scales to billions of messages), device shadow (persistent last reported/desired state), rules engine (SQL-like routing to Lambda/DynamoDB/S3/Kinesis/Timestream), and AWS IoT Greengrass (edge computing for local rules and ML inference).
Telemetry Dashboard
Real-time device monitoring dashboard: Grafana + Timestream (time series database for sensor data, automatic tiering, fast aggregation queries), custom React dashboard (device list with online/offline status, sensor history charts, alert history, geospatial map view), threshold alerts (PagerDuty/Slack/email when sensor exceeds defined thresholds).
OTA Update System
Over-the-air firmware updates for device fleets: A/B partition scheme (active/inactive partitions, download to inactive, verify signature, boot into new, automatic rollback on failure), AWS IoT Jobs (orchestrate deployments to device groups, staged rollout, real-time progress monitoring), delta updates (download only changed sectors, minimise cellular data cost).
Data Pipeline & Storage
IoT data processing: AWS IoT Rules Engine (conditionally route messages), Amazon Timestream (time series database automatic data tiering, built-in aggregation functions), Kinesis (stream processing for real-time analytics), S3 (long-term cold storage of raw telemetry).
