Question 1

What is the Sensorbee Pro 2?

Accepted Answer

The Sensorbee Pro 2 is a professional-grade, ultra-low-power air quality monitoring station designed for outdoor urban and industrial environments. It provides indicative measurements for particulate matter and various gases, combining rugged hardware with cloud-based data intelligence to give cities, industries, and researchers continuous, actionable environmental insights.

Question 2

What parameters can the device measure?

Accepted Answer

The Pro 2 features a modular sensor design. Particulate Matter: PM1, PM2.5, and PM10 sensors included as standard. Gases: Up to six slots — one fixed CO2 slot and five electrochemical slots for NO, NO2, SO2, H2S, and NH3 (Ammonia). Weather Conditions: Ambient temperature, relative humidity, and atmospheric pressure.

Question 3

Is the device suitable for harsh outdoor use?

Accepted Answer

Yes. The Pro 2 is engineered specifically for the outdoors. It features a sealed internal compartment that shields all electronics from corrosion, condensation, and moisture ingress. The enclosure meets IP65 standards, meaning it is fully dust-tight and protected against water jets from any direction — making it reliable in rain, coastal air, and industrial atmospheres alike.

Question 4

What integration options are available?

Accepted Answer

Sensorbee offers three primary pathways: 1) Cloud-to-Cloud Forwarding — data flows to the Sensorbee portal and is forwarded to your platform via APIs or webhooks. 2) Direct LWM2M Integration — the device communicates directly with your own LWM2M server. 3) Physical Integration — connect via cabling to existing monitoring stations or data loggers.

Question 5

What communication protocols are supported?

Accepted Answer

The Pro 2 uses LWM2M (Lightweight Machine-to-Machine) protocol over NB-IoT or Cat-M cellular networks. LWM2M is an open standard that provides structured device management, remote firmware upgrades, and high-security data transport via DTLS (Datagram Transport Layer Security).

Question 6

Does the device work globally?

Accepted Answer

The hardware is technically compatible with 5G-deployed NB-IoT and Cat-M networks, covering the majority of Western Europe, North America, and China. The device currently holds CE marking for the European market. Additional regional certifications such as FCC (USA) or RCM (Australia) can be arranged.

Question 7

What are the power options?

Accepted Answer

The Pro 2 is optimised for solar-powered deployments. A 14-watt panel is typically sufficient for mid-latitude locations, while a 30-watt panel is recommended for high-latitude or gas-sensor-heavy configurations. The device can also be connected directly to mains power (230V AC) for permanent installations.

Question 8

How long does the internal battery last?

Accepted Answer

Under standard operating conditions — polling every 10 minutes with a typical sensor load — the internal battery provides approximately two weeks of autonomous operation without any solar or mains input. Battery life can be extended further by enabling nighttime low-power modes or increasing the polling interval.

Question 9

Can the battery charge in cold climates?

Accepted Answer

Yes. The Pro 2 uses specialised lithium battery chemistry engineered for cold environments. It can accept charging current at temperatures down to -20 degrees C and continue delivering power to sensors at temperatures as low as -30 degrees C — suitable for Arctic monitoring, alpine deployments, and winter city networks.

Question 10

How often does the device need calibration?

Accepted Answer

Calibration requirements differ by sensor type. Particulate Matter Sensors are guaranteed for two years without recalibration. Gas Sensors (Electrochemical) require a baseline drift correction approximately every two weeks, which is performed automatically by cloud algorithms with no manual field intervention.

Question 11

How is long-term maintenance handled?

Accepted Answer

Sensorbee recommends a sensor exchange programme rather than traditional field recalibration. All sensor elements are hot-pluggable and tool-free to swap. Sensorbee ships pre-calibrated replacement elements every two years. The operator simply swaps the element on-site in minutes.

Question 12

Can I monitor the health of my sensors?

Accepted Answer

Yes. The Pro 2 continuously monitors its own internal health and reports diagnostics to the cloud dashboard. Parameters tracked include internal relative humidity, short-circuit detection on sensor element connections, and dust accumulation levels on optical particulate sensors — allowing predictive maintenance.

Question 13

How frequently can I receive data readings?

Accepted Answer

The industry standard is a 15-minute average, but the Pro 2 supports higher resolution: Standard (15 min), Enhanced (5 min, most deployments), and Maximum (1 min, mains powered). Higher polling rates increase power consumption. The optimal interval depends on active sensor modules and available power source.
