EnviroSense Environmental Sensor Module

The Sensorbee EnviroSense Module (SB4502) is a combined environmental sensor module designed for meteorological and climate monitoring applications. It provides high-accuracy measurement of temperature (±0.2 °C), humidity (±1.5 %RH), and barometric pressure (300 to 1250 hPa) from a single 5-gram package. Every Air Pro 2 ships with the EnviroSense module as standard, making it a core component of the Sensorbee monitoring ecosystem.

How It Works

The SB4502 combines capacitive humidity sensing, resistive temperature measurement, and piezoresistive pressure measurement into a single compact module. The module samples the local environment continuously and outputs data to the Air Pro 2 base station, where it is combined with particulate matter, gas, and noise data for unified transmission to the Sensorbee Cloud.

Measurement Parameters

The EnviroSense delivers three environmental measurements in a single module:

• Temperature — –20 to 50 °C with ±0.2 °C accuracy. Accurate temperature data is essential for environmental baseline reporting and supports correction algorithms for other sensor measurements.
• Relative Humidity — 0–100% RH with ±1.5 %RH accuracy (0–95 %RH), improving to ±1.0 %RH in the 20–75 %RH range at 15–55 °C. Humidity data is essential for interpreting particulate matter readings, assessing condensation risk, and understanding local microclimate conditions.
• Barometric Pressure — 300–1250 hPa with ±0.5 hPa accuracy. Accurate pressure data supports meteorological context for air quality analysis and enables altitude-corrected calculations.

Why the EnviroSense Matters

Environmental monitoring data without meteorological context tells only half the story. The EnviroSense provides the baseline environmental parameters that transform raw pollutant measurements into actionable insights.

• Humidity correction for particulate data — humidity directly affects optical particle counter readings. Collocating precise humidity measurement with the particle sensor enables data validation and correction, improving the accuracy of reported PM concentrations.
• Temperature baseline — accurate temperature measurement supports environmental reporting requirements, thermal comfort assessment, and correction of temperature-sensitive sensor outputs.
• Meteorological context — barometric pressure data supports weather-correlated analysis of pollution episodes and enables dispersion modelling with site-specific meteorological inputs.

Integration With the Air Pro 2

The EnviroSense is included as standard with every Air Pro 2 monitoring station. The module plugs into the base unit's internal sensor bus and is automatically detected — no configuration, wiring, or setup is required. Data from the EnviroSense appears alongside all other sensor measurements on the Sensorbee Cloud dashboard.

Because the module weighs just 5 grams and measures D20 × 24 mm, it adds negligible size and weight to the monitoring station. The polyamide enclosure provides protection across the full -20 to +60°C and 0–100% RH operating range.

Applications

• Construction site environmental monitoring — complement dust and noise data with temperature, humidity, and barometric pressure for comprehensive environmental reporting and conditions analysis
• Urban air quality networks — provide meteorological context for particulate and gas measurements across city-wide monitoring deployments, enabling weather-corrected air quality analysis
• Environmental research — multi-parameter environmental data from a single compact sensor supports field research where minimising instrument count and power consumption is important
• Weather monitoring — temperature, humidity, and pressure data support meteorological assessment and climate data collection

Frequently Asked Questions

Is the EnviroSense included with the Air Pro 2?

Yes. Every Air Pro 2 monitoring station ships with the EnviroSense module (SB4502) as standard equipment. No additional purchase is required.

Can the EnviroSense be used as a standalone sensor?

The EnviroSense is designed for integration with the Air Pro 2 sensor bus. It does not operate independently or connect directly to external data loggers.

How long does the module last?

The EnviroSense has an operational life exceeding two years under normal operating conditions. Replacement modules are available from Sensorbee when service intervals are reached.

What is the temperature accuracy?

The EnviroSense measures temperature from –20 to 50 °C with ±0.2 °C accuracy. This provides reliable environmental baseline data for site monitoring and reporting.
