Condition monitoring
Collect temperature, humidity or another agreed measurement from an appropriate sensor. The application displays readings, timestamps and the most recent device communication.
Make physical events visible
IoT Sensors & Connected Devices
Connect measurements and physical events to software your team can use. We develop sensor-based prototypes and integrations with dashboards, notifications and defined operating rules.
Custom applications
What this technology can help you build
Examples for planning a project. Configuration and scope are confirmed around your environment and the required testing.
Events and counters
Record events such as an opening, a switch change or a counted passage using a suitable sensor. Filtering and timing rules help prevent repeated or noisy signals from becoming misleading records.
Custom connected prototypes
Bring a controller, sensors, optional RFID reader and enclosure into a testable assembly. Firmware sends data to a dashboard or API with a defined plan for configuration and maintenance.

The operating need
Technology shaped around the work.
A useful monitoring system includes more than a sensor and a Wi-Fi connection. It needs a suitable measurement method, stable power, clear device identity, reliable data handling and a way to respond when something stops communicating. Carras Technologies develops connected-device projects using platforms such as ESP32 where they fit the requirements. We bring together purchased sensors, embedded programming, APIs and software, with optional custom enclosures. The work starts with a defined measurement or event and a pilot that checks the behavior in its intended environment.

Common signals
When the current process starts getting in the way
A project should begin with a visible operating constraint, not a vague request for more technology.
Staff must check a condition manually because the information is not available remotely.
Physical events never reach the dashboard or workflow used by the business.
An early device prototype needs firmware, data handling and a practical enclosure.
Engagement scope
What the work can include
The final scope is defined during discovery and documented before implementation begins.
1
Sensor, controller, power and connectivity assessment
2
ESP32 or suitable controller firmware and device integration
3
Data ingestion, dashboards, thresholds and agreed notification channels
4
Pilot testing, connection-loss behavior and maintenance documentation
Delivery model
A clear path from operating need to maintained system
Discover
Clarify the operating problem, users, information, constraints, and desired business outcome.
Design
Define the workflow, system boundaries, experience, architecture, risks, and delivery plan.
Build
Develop in focused milestones with review, testing, documentation, and visible progress.
Operate
Launch responsibly, monitor the system, support users, and improve it using real feedback.
Business outcome
Designed to improve the operation
- Make selected conditions visible to the people responsible
- Keep a history of measurements and device events
- Use defined thresholds and workflows to support timely follow-up
Frequently asked
Is ESP32 a sensor?+
ESP32 is a family of microcontrollers used to process inputs and connect devices. It works with separate sensors and other components. We choose the specific board and interfaces around the measurement, connectivity and power requirements.
Can the system send alerts to a phone or dashboard?+
Yes, where the selected channel and integration support it. The project defines thresholds, recipients, notification delays and acknowledgments. We also consider how a user will distinguish a normal reading from an offline or stale device.
What happens when Wi-Fi or power fails?+
That behavior is part of the design. Depending on the hardware and scope, a device can buffer readings, reconnect, report its last-seen time or use an alternative connection. Backup power and offline operation must be specified and tested rather than assumed.
Can you connect sensors to software we already use?+
We review the software's APIs, data formats and access controls. A project may use a dedicated dashboard or connect to an existing operational system, with clear ownership of credentials and device configuration.
Do you build industrial control or safety systems?+
We assess each request separately. A monitoring prototype does not establish suitability for safety-critical control, hazardous environments or regulated use. Those requirements need an explicitly qualified design, appropriate equipment and validation.
