Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Grain Silo Temperature Monitoring (Fire, Spoilage & Loss Prevention)
Prevents fermentation & fire
Temperature
Quick Overview
| Problem | Stored grain is highly sensitive to temperature rise caused by moisture pockets, biological activity, or poor ventilation. Undetected hotspots can lead to spoilage, mould development, insect proliferation, or silo fires—often discovered too late during manual inspections. |
| Solution | Sensa.io’s wireless temperature sensors continuously monitor grain silo temperature profiles, detecting hotspots early and enabling proactive aeration or unloading actions. |
| Value | Reduced spoilage • Fire risk prevention • Preserved grain quality • Lower insurance and loss costs |
| ATEX | Grain silos may fall under ATEX Dust Zones; ATEX-certified temperature sensor variants available (Zone 20–22) |
The Operational Challenge
Grain silos are used to store wheat, corn, barley, soy, and other cereals over long periods.
Key risk factors include:
- Moisture migration inside the grain mass
- Biological respiration generating heat
- Poor airflow or blocked aeration ducts
- Seasonal temperature fluctuations
Typical problems faced by operators:
- Localised heating invisible from the surface
- Condensation zones leading to mould growth
- Insect infestation accelerated by warmth
- Smouldering grain or dust ignition
Traditional monitoring methods rely on:
- Manual probing or handheld thermometers
- Visual inspection of exhaust air
- Reactive action after odour or smoke appears
These methods provide limited spatial and temporal visibility.
Why Continuous Temperature Monitoring Matters
Temperature is the earliest indicator of grain degradation.
Continuous monitoring enables operators to:
- Detect hotspots before spoilage spreads
- Activate aeration only when needed
- Prevent spontaneous combustion
- Preserve grain quality and market value
Even a few degrees of abnormal temperature rise can signal serious storage issues.

FAQ - Common Questions
Are Sensa.io sensors compatible with any gateway or network?
What ATEX certifications apply to Sensa.io devices?
All hazardous-area models are certified Ex II 2 G Ex ia IIC T4 Gb and IECEx approved for Zones 0–2.
What is the typical battery life?
Up to 10 years at 15-minute intervals, depending on signal strength and environment.
How are the sensors integrated into existing systems?
Through standard protocols — LoRaWAN, Modbus, MQTT, REST API — no proprietary middleware needed.
How does predictive maintenance reduce OPEX?
Early anomaly detection reduces emergency interventions by 30–40 %, extends equipment life and lowers energy costs.
What does the Sensa.io Valve Position Sensor actually measure?
The device detects real-time valve position states—open, closed, or intermediate—with high accuracy. It continuously sends this information wirelessly to your monitoring dashboard.
Can this sensor detect partial valve movement or stuck valves?
Yes. The sensor identifies irregular patterns such as partial movement, delayed response, or stuck valves, enabling early maintenance before failure occurs.
Is this sensor suitable for manual, motorized, and actuated valves?
Yes. It supports a wide range of valve types including ball, gate, butterfly, actuator-driven, and manual valves.
How fast does it update the valve position?
You can configure the reporting interval—from seconds to minutes—depending on your operational and battery needs.
How long does installation take?
Most installations take under 10 minutes. The sensor mounts using brackets or clamps without modifying existing valves.
