Specialisation
IoT design office
From sensor to cloud — our engineers develop your industrial IoT solutions end to end: custom hardware, embedded firmware, wireless protocols.
Industrial IoT
end to end
An IoT project is rarely just a board with a radio module. It is a complete chain: sensor, local processing, communication protocol, network, cloud integration. At Codium, we master every link on the hardware and firmware side.
We design industrial IoT solutions, autonomous sensor networks, field gateways and low-power connected devices. From a single prototype to series production.
What sets us apart: our engineers choose the protocol that suits your context — range, power consumption, node density, existing infrastructure — not simply the one they know best.

The right protocol
for your project
Each IoT protocol has its advantages depending on the context. Our engineers help you choose, then design the matching hardware and firmware.
Long range (several km), very low power consumption, public TTN or private network. Ideal for outdoor sensors and wide field networks.
Compare LoRa / LTE-M →Dedicated 4G cellular network for IoT. Mobility, nationwide coverage, SIM. Perfect for geolocation, mobile equipment and devices that report data frequently.
Our LTE-M expertise →Private industrial network with no operator infrastructure. Low latency, reliability, high node density. The solution for factories and warehouses that want to control their own IoT network.
Our DECT NR+ expertise →Short-range local connection, very low power consumption. Ideal for wearables, sensors close to a gateway and smartphone interaction.
Wi-Fi for high-bandwidth devices or those integrated into an existing infrastructure. Zigbee for indoor mesh networks (smart building, industrial home automation).
A device can embed several radios: BLE for local configuration, LTE-M for cloud reporting, GNSS for position. Our engineers master multi-radio architectures.
From measurement
to cloud
Codium works on the hardware and firmware layers of the IoT chain. We design each link to be reliable, energy-efficient and compatible with your existing infrastructure.
Measurement electronics (analogue, digital, MEMS), low-power microcontroller, integrated radio. Battery life optimised from the design stage.
Sleep/wake cycle management, local processing, radio stack (LoRaWAN MAC, LTE-M AT, BLE stack), end-to-end encryption and OTA updates.
Field concentrator (LoRa gateway, BLE→LTE-M gateway) or direct integration on an operator network. Hardware and firmware design where needed.
Payload format, application protocols (MQTT, CoAP, HTTP), integration with AWS IoT, Azure IoT Hub, The Things Network or your in-house platform.
IoT solutions we develop
From autonomous industrial sensors to mobile trackers and environmental monitoring networks — our engineers work in a wide variety of contexts.
Temperature, vibration, pressure and current measurement — wireless transmission over LoRa or LTE-M. 5+ years of battery life.
GNSS + LTE-M trackers for fleets, mobile assets and construction-site equipment. Position reporting in real time or deferred.
Energy metering, ambient monitoring, building technical supervision. Zigbee, LoRa or DECT NR+ networks.
Soil probes, connected weather stations, air or water quality monitoring. Long-range LoRa for the field.
Equipment supervision, predictive maintenance, machine retrofitting with no change to the existing network.
Wearable monitoring devices, BLE biomedical sensors. Miniaturisation, low power consumption, standards compliance.
IoT is a specialisation of our full-service design office
Codium is first and foremost a general electronics design office. IoT is a strong specialisation — but we can design your entire product, even if part of it is not connected.

Everything you need to know about our IoT design office.
Which IoT protocols do you master?
Codium masters all current wireless IoT protocols: LoRa / LoRaWAN for long-range LPWAN networks, LTE-M and NB-IoT for cellular connectivity, DECT NR+ for private industrial networks, Bluetooth LE for local links, Wi-Fi and Zigbee for building infrastructure.
We choose the protocol that suits your context: range, power consumption, bandwidth, existing infrastructure, connectivity cost.
Can you develop a custom industrial connected sensor?
Yes. Codium designs custom connected sensors for industry: temperature, pressure, vibration, current, flow, position. We handle the measurement electronics, the processing firmware and the wireless connectivity (LoRa, LTE-M, BLE), through to series manufacturing.
Do you also develop the IoT cloud / backend?
Our core business is electronics and embedded firmware. We do not develop the cloud backend, but we design devices to integrate with existing platforms (AWS IoT, Azure IoT Hub, The Things Network) and we support you in choosing the end-to-end architecture.
What battery life can be achieved?
A LoRa or LTE-M node in deep sleep can drop below 10 µA. With data reported every hour, a battery life of 5 to 10 years on an AA cell is realistic depending on the protocol and payload. Codium optimises every design to maximise battery life from the schematic stage.
How much does it cost to develop a complete IoT solution?
The budget depends on complexity: a simple sensor (LoRa + 2-3 measurements + firmware) starts at around €15,000 to €25,000 for the design and first prototype. A multi-sensor solution with a gateway can reach €60,000 to €100,000. We provide a detailed estimate at the first discussion.
