Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Cleanroom ΔP & Air Quality Monitoring (GMP & Contamination Control)
GMP compliance
Differential Pressure (ΔP)
Temperature
Quick Overview
| Problem | Cleanrooms and controlled environments in pharmaceutical, fine chemical, and high-purity process industries rely on precise pressure differentials and air quality control. Loss of differential pressure (ΔP) or airflow imbalance can lead to contamination, batch rejection, regulatory non-compliance, and costly downtime—often without immediate visibility. |
| Solution | Sensa.io’s wireless differential pressure and temperature sensors provide continuous monitoring of cleanroom pressure cascades and ventilation performance, ensuring GMP compliance and contamination control. |
| Value | GMP compliance • Reduced contamination risk • Lower audit effort • Stable production |
| ATEX | Generally non-ATEX; ATEX-certified sensor variants available when installed in solvent handling or classified zones |
The Operational Challenge
Cleanrooms are used in chemical and process industries for:
- Pharmaceutical synthesis and formulation
- Fine chemicals and specialty materials
- High-purity packaging and filling
- Controlled laboratory and pilot environments
They depend on:
- Stable pressure differentials between zones
- Controlled airflow direction and volume
- Reliable HVAC and filtration performance
Typical challenges include:
- Loss of pressure cascade due to filter clogging
- Fan degradation or damper malfunction
- Undetected airflow imbalance between rooms
- Manual checks too infrequent for continuous assurance
Traditional monitoring often involves:
- Local manometers or gauges
- Periodic manual readings
- Reactive investigation after alarms or deviations
This leaves significant blind spots between inspections.
Why ΔP & Air Quality Monitoring Matter
Differential pressure is the primary indicator of cleanroom integrity.
Continuous monitoring enables operators to:
- Maintain correct pressure cascades between zones
- Detect filter clogging and ventilation issues early
- Prevent contamination ingress or cross-contamination
- Provide continuous proof of GMP compliance
Temperature data further supports HVAC performance analysis and comfort control.

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.
