We bridge the gap between your physical operations and digital intelligence — sensors, devices, and machines talking to each other, and to you, in real time.
The Internet of Things connects physical devices — sensors, cameras, meters, actuators, machines — to a digital network where they can transmit data, receive commands, and respond to events automatically, without human intervention.
Casterly Crown designs and deploys end-to-end IoT systems: from the hardware selection and sensor installation, through the connectivity layer and cloud platform, all the way to the dashboard where you watch everything in real time — and the automation rules that take action before you even look at it.

Sensors on production machinery detect vibration, temperature, and pressure anomalies — triggering maintenance alerts before a breakdown stops the line.
Temperature and humidity sensors inside refrigerated trucks and storage facilities send live readings — alerting you the moment conditions leave safe ranges.
Soil moisture, sunlight, and irrigation sensors automate water distribution — delivering exactly what each crop needs, when it needs it, with zero manual intervention.
HVAC, lighting, access control, and energy consumption managed through a single IoT platform — cutting utility costs and improving occupant comfort automatically.
Wearable and bedside IoT devices stream vital signs continuously — alerting clinical staff to deteriorating patients in real time, reducing emergency response times.
Shelf weight sensors trigger automatic reorder when stock runs low. Footfall counters optimise staff deployment. Refrigerator monitors prevent spoilage losses overnight.
Remote meter reading, leak detection in water networks, and grid load balancing — all managed without field engineers making manual rounds.
Four layers from physical to insight
Physical sensors, actuators, cameras, and edge devices collect raw data from your environment — temperature, pressure, motion, position, energy consumption. We advise on hardware selection, source it, and manage installation across your facilities.
SENSOR_001 → 28.4°C ✓
SENSOR_002 → 1.02 bar ✓
SENSOR_003 → MOTION: 0 ✓
polling interval: 500ms
Device data travels to the cloud over the most appropriate protocol for your environment — WiFi for high-bandwidth indoor, LoRaWAN for long-range low-power outdoor, 4G/5G for mobile assets, or Zigbee for dense mesh deployments. We design the network so nothing drops.
// Protocol negotiation
DEVICE → MQTT broker
TOPIC: cc/factory/line2
QoS: 1 — ACK received
latency: 11ms
Raw telemetry lands in our AWS-hosted IoT platform where it is stored, aggregated, and run through rule engines. Thresholds trigger instant alerts. Time-series analysis surfaces trends. Machine learning models predict failures before they happen.
// Rule engine evaluation
IF temp > 35°C
AND duration > 5m
THEN alert.send("ops-team")
THEN hvac.setCooling(MAX)
Every stakeholder sees exactly what they need — operations managers get real-time floor maps, executives see KPI dashboards, maintenance teams receive prioritised alerts on their phones. And where automation rules aren't enough, manual override controls are one tap away.

We evaluate your use case and recommend the right sensors, microcontrollers, gateways, and edge devices — sourced and tested before deployment.
MQTT, CoAP, LoRaWAN, Zigbee, BLE, 4G — we match connectivity protocol to environment, power constraints, and data velocity requirements.
Live dashboards showing sensor readings, device health, and operational KPIs — accessible from any device, anywhere, with configurable alert thresholds.
We build on AWS IoT Core — the enterprise-grade backbone for device management, telemetry ingestion, rule engine, and integration with the rest of your cloud stack. Secure device provisioning, over-the-air firmware updates, and fleet management all included.
Beyond simple alerts — we build intelligent rule engines that take automatic action based on sensor readings. HVAC adjusts itself. Machines slow down before overheating. Reorders trigger before stockouts. When paired with ML models, the system predicts failures days in advance.
Encrypted device communication, certificate-based authentication, and network segmentation — every device in the fleet is verified and monitored for anomalous behaviour.
Typically 6 – 16 weeks from discovery to live sensors
We visit your facility, map the physical environment, understand your operational pain points, and identify exactly where sensors will deliver the most value.
Hardware selection, network topology, cloud platform design, and automation rule specifications — documented and approved before a single device is ordered.
We instrument a small section of your operation first — prove the concept, validate data quality, and tune automation rules before scaling across the site.
Phased deployment across all zones with zero disruption to operations. Every device configured, tested, and verified before handover.
Your operations team trained on the dashboard, alert management, and device health monitoring. Documentation delivered. We don't disappear at go-live.
Remote monitoring of your IoT fleet, firmware update management, and a retainer for system expansions — as your operation grows, your IoT network grows with it.
Tell us what you're monitoring, what decisions you're making manually, and what you wish you could know in real time. We'll show you exactly how IoT can change the picture.
