Industrial wireless
temperature monitoring
Sense-i temperature nodes put a reading on every point that matters across a plant, store or utility area, without pulling a cable to each one. We plan the radio and the power for your building, prove both on site, then roll out.
THE PROBLEM
Temperature matters at dozens of points, and each one needs a cable
In most plants, temperature is checked where the instrument happens to be: the control panel, the chiller display, a thermometer on a wall. The places that cause trouble are elsewhere. A mezzanine store that bakes in summer, a raw material room next to the boiler house, a motor room with poor ventilation, a curing area at the far end of the shed.
A wired system to cover those points means cable trays, conduit, a hot-work permit for every penetration and a shutdown window to do it in. That is why many sites still rely on a walk-round with a clipboard, and why a problem is usually found after the product or the equipment has already suffered.
Wireless nodes change the economics. The hard question moves from "how do we cable it" to "will the radio reach and how long will the battery last in this building", and both can be answered with a short site test.
HOW WE SET IT UP
From site survey to a full network
Choose the radio for the building
Where Wi-Fi 2.4 GHz or 4G LTE reaches, each node reports directly to the cloud. Across large sheds, steel structures or several buildings, we add LoRa or Zigbee with a site gateway that we size for the layout.
Prove coverage and battery on site
We install a small set of nodes at the hardest points first: inside steel enclosures, behind racking, at the far end of the site. Signal quality and battery draw at your reporting interval are measured before the full order is built.
Probe where the reading matters
Room air, surface or immersion readings call for different probes. Sense-i takes a built-in sensor or a PT100 probe, so the node can sit outside a hot or cold space while the probe goes in.
Alarms that act on the node
Thresholds and alarms run on the node itself, with relay outputs for a local beacon or fan. RIOD Live then sends the alert by SMS, call, WhatsApp, email or push to the people on shift.

FAQ
Questions buyers ask us
Do wireless temperature sensors work in a steel factory building?
Yes, once coverage has been tested at the hardest points. Steel structures, racking and enclosures block and reflect radio signals, so we prove the signal there before the full rollout. Where Wi-Fi is weak we use 4G per node, or LoRa or Zigbee with a gateway placed for the layout.
How long does the battery last in a wireless temperature sensor?
Battery life is set by the reporting interval, the radio and the signal strength at each point, so we measure the actual draw during the site trial. We then choose the battery capacity, from about 2,000 mAh upwards, or adapter power where a socket is close by.
What happens to the readings if the network goes down?
Each Sense-i node keeps logging to flash memory, holding roughly 10,000 to 40,000 records, and sends the backlog when the connection returns. The history in RIOD Live stays complete.
Can the data go to our own server or SCADA?
Yes. Nodes publish over MQTT with TLS 1.2. We can point them at RIOD Live, set RIOD Live up on your own server, or deliver the data into your system through an API.
Need temperature at points you cannot cable?
Send us the site layout, the number of points and the alarm limits. We will propose the radio, the probes and a short site trial.
