SISCO smart air quality sensor integrates multiple gas detection channels into a single compact unit. Various output interfaces simplify connectivity to existing equipment. Advanced circuitry maintains measurement accuracy over extended periods. Low-power design reduces operating costs. Plug-and-play architecture minimizes setup complexity.
Multi-Gas Monitoring with Modular Flexibility
- Supports up to four core parameters in one compact unit, eliminating the need for multiple separate instruments.
- Allows users to select and combine detection modules based on specific application requirements, avoiding unnecessary features and reducing overall cost.
- Delivers stable readings with 1-second update intervals, ensuring continuous and timely air quality data.
- Maintains measurement accuracy over extended periods without calibration drift, thanks to advanced signal processing circuitry.
Versatile Output Interfaces for Seamless Integration
- Standard RS485 (Modbus) output enables direct integration with PLC, DCS, and building automation systems commonly used in industrial environments.
- Optional 4-20mA and 0-10V analog outputs provide compatibility with traditional control equipment requiring standard industrial signals.
- Wireless interfaces including Bluetooth and WiFi allow easy connection to smart home gateways, mobile devices, and cloud platforms.
- Plug-and-play architecture and flexible output selection simplify system design and reduce installation time without requiring additional signal converters.
Applications

Q1: How to read and interpret the data from this smart air quality sensor?
A1: The sensor updates all gas readings every second. For CO2, levels below 1000ppm indicate good ventilation; CH2O below 0.08mg/m³ is considered safe; O2 should stay between 19.5%-23.5%Vol for human comfort; CH4 and CO readings above 10%LEL and 50ppm respectively, may trigger safety alerts. All data can be accessed via RS485, 0-10V, or 4-20mA outputs.
Q2: What output options does this smart air quality sensor support for system integration?
A2: Modbus-RS485 comes as standard, with 0-10V, 4-20mA, Bluetooth, and WiFi available as optional interfaces. These outputs enable direct connection to PLCs, building automation systems, IoT gateways, and mobile devices without extra converters.
Q3: How should this smart air quality sensor be installed and powered?
A3: Both wall-mounted and ceiling-mounted installations are supported. It operates on DC 10-30V (standard 24V), drawing < 200 mA, with a 2-minute warm-up time. The compact 100×100×30mm ABS housing fits most indoor environments.
Tips: What should I consider when deploying this smart air quality sensor for accurate CO2, TVOC, HCHO, and PM2.5 monitoring?
- Allow at least 2 minutes of warm-up time after power-on before taking readings, as the sensor needs this period to stabilize and deliver accurate measurements.
- Avoid placing the sensor near direct airflow sources such as vents, fans, or open windows, as strong air movement may cause fluctuating or unrepresentative readings.
- Mount the sensor at breathing height (approximately 1.2–1.5 meters above floor level) for wall-mounted installation, as this represents the most relevant air quality level for human exposure.
- Perform periodic verification of measurement accuracy using calibration gas or comparison with a reference instrument to ensure long-term reliability.
