Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Ventilation System Temperature & ΔP Monitoring (Silos & Livestock Buildings)
Reduces explosion risks
Temperature
Differential Pressure (ΔP)
Quick Overview
| Problem | Agricultural ventilation systems in silos and livestock buildings are critical for controlling temperature, humidity, dust, and gas concentration. Undetected airflow restriction, fan degradation, or temperature imbalance can lead to spoilage, animal stress, disease spread, or explosion risk in dusty environments. Manual checks provide limited and delayed visibility. |
| Solution | Sensa.io’s wireless temperature and differential pressure (ΔP) sensors continuously monitor ventilation performance, ensuring correct airflow, thermal stability, and safe operating conditions. |
| Value | Improved air quality • Reduced spoilage & animal stress • Lower energy use • Safer operations |
| ATEX | Dust-prone zones may require ATEX; ATEX-certified temperature & ΔP sensor variants available |
The Operational Challenge
Ventilation systems are used across agricultural assets:
- Grain silos and storage facilities
- Poultry and livestock buildings
- Feed storage and handling areas
- Dust extraction and air renewal systems
They must ensure:
- Adequate airflow rate
- Stable temperature distribution
- Removal of humidity, ammonia, and dust
- Energy-efficient operation
Common operational issues include:
- Clogged air filters or ducts
- Fan degradation or imbalance
- Uneven airflow distribution
- Temperature stratification
- Excessive energy consumption
Traditional monitoring relies on:
- Manual airflow checks
- Spot temperature readings
- Fixed maintenance schedules
These methods often detect problems only after quality or welfare is compromised.
Why Temperature & ΔP Monitoring Matter
Temperature and ΔP together provide a complete picture of ventilation health.
Continuous monitoring enables operators to:
- Detect airflow restriction early
- Identify ventilation inefficiencies
- Maintain stable environmental conditions
- Reduce dust accumulation and gas concentration
- Optimise fan runtime and energy use
Stable ventilation directly impacts product quality, animal welfare, and safety.

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.
