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.
The first step
A defined pilot before expanding the system.
Start with one use case and a bounded test. The proposal confirms equipment, quantities, deliverables, price and schedule before work begins.
01 / Define the test
Choose one condition to measure, the sensor, sampling frequency, power supply and test location.
02 / Connect the path
Connect the device to a data view that distinguishes the measurement, timestamp and last communication. Alerts are included when agreed in scope.
03 / Check the results
Test readings, agreed thresholds and behavior when connection or power is lost and restored.
04 / Deliver and decide
Document configuration, results, limitations and next steps. Pilot evidence supports a decision to adjust, expand or stop that technical approach.
How remote delivery works
- CARRAS
- Agreed design and integration, programming, setup instructions and remote review of test results.
- Client or local technician
- Site and equipment access, physical mounting, power, network and on-site tests according to the agreed plan.
- Before starting
- Define who buys and receives each component, who installs it and which access is required. Site visits are outside our remote service.
What is agreed in writing
- Acceptance: test scenarios, metrics, thresholds and evidence to review. A prototype does not guarantee performance at a larger installation.
- Handoff: included files, configuration, access and documentation, with usage and ownership terms.
- Operations: hosting, licenses, connectivity and other recurring costs; responsibility for monitoring, updates and backups.
- Support: delivery coverage, how to report issues and which maintenance or changes require an additional agreement.
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 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.

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.
