CASE STUDIES

IoT Project We Have Developed

Representative examples of the kind of connected product work we take on.

Utility / Metering

Smart Metering IoT Gateway Development

Problem: a utility company had a need for a gateway that would collect data from many smart meters and transmit it to the cloud. Solution: we developed a gateway with Modbus to MQTT protocol conversion and cellular uplink with a local buffer of data. Effect: reliable data transmission despite cellular connection disruptions, providing centralized visibility into meter data without upgrading meters.

Industrial IoT

Industrial IoT Asset Monitoring with LoRa WAN Nodes

Problem: a manufacturing facility needed vibration and temperature monitoring distributed across the plant equipment with no pre-existing Wi-Fi coverage. Solution: we implemented LoRa WAN wireless sensor node devices transmitting their data to a central gateway and cloud dashboard. Effect: battery life of several years obtained despite no existing coverage throughout the plant, allowing to monitor equipment health without additional wiring.

Logistics / Cold Chain

Cold Chain IoT Monitoring Cloud Dashboard

Problem: our logistics client required real-time temperature tracking of its refrigerated fleet. Solution: we developed a set of cellular temperature loggers with a cloud dashboard. Effect: real-time visibility into cold chain breaches within the fleet.

KNOW THE BASICS

What is IoT (Internet of Things)?

Internet of Things is a collection of hardware - sensors, actuators, and gateways that have network interfaces. These devices are connected and send/receive data. Typically, these data streams terminate on a cloud service where they can be viewed, processed, or acted upon remotely. Soil moisture sensor reporting over LoRa WAN, industrial vibrations monitor sending data to a dashboard, or a smart meter reporting its current consumption over cell are all considered IoT devices. Building a useful IoT device depends on getting these three layers working together properly - how you capture data on the hardware (hardware and sensing), get the data off the device (firmware and connectivity), and process the data into something that a human or system can use (cloud platform). Break any of these links in the chain and your IoT device doesn't work.

IoT is often used to monitor
  • • Industrial assets and conditions
  • • Smart agriculture and environment
  • • Smart meters and energy usage
  • • Cold chain and logistics
  • • Smart buildings and facilities
  • • Remote equipment and predictive maintenance
An IoT deliverable should provide
  • • Sensor/edge devices: hardware & firmware
  • • Connectivity: module & range check
  • • Cloud platform: setup & device provisioning
  • • Device management: including OTA functionality
  • • Security: encryption & authentication
FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

Questions we hear on every IoT scoping call — answered directly, without the brochure language.

What do I get with Rhosigma's IoT development service?

▾

This includes integration of sensor and edge devices; design of connectivity (Wi-Fi, BLE, LoRa WAN, cellular); development of firmware and gateways; integration of devices into your backend application and cloud service with OTA update support.

What IoT connectivity is available for IoT products from Rhosigma?

▾

We develop devices designed for, and integrated using, Wi-Fi, Bluetooth Low Energy, LoRa WAN, NB-IoT, Zigbee and cellular (4G/5G) communication technologies, depending on each device's power budget and operational range.

Can Rhosigma integrate my IoT device with AWS or Azure?

▾

Certainly! We have experience integrating IoT products with AWS IoT Core, Azure IoT Hub, Google Cloud IoT and your own backend systems using any combination of MQTT, CoAP, HTTP/REST.

How long will my IoT product development project take?

▾

A sensor node with standard, pre-developed communication modules can be designed in 6 to 10 weeks. A full IoT product with custom hardware, firmware, and Cloud integration, would likely take 3 to 6 months depending on the complexity of the solution.

Do you provide an IoT gateway solution?

▾

Yes, Rhosigma can design and implement IoT gateways that will aggregate information from field devices (sensors using LoRa WAN, Zigbee, or Modbus, for example) and will forward this data to your chosen cloud services via a wired, Wi-Fi, or cellular (GSM, LTE) connection.

How is IoT device security managed by Rhosigma?

▾

Security features for devices are implemented during the IoT firmware design process. This typically includes TLS/DTLS secured communication and authentication for devices, as well as secure boot. Device management systems are designed in a way so that secure OTA updates will work without security issues.
