S-19 Wireless CO2 Sensor

Our S-19 CO₂ Sensor is ideally suited to continuous real time monitoring of building CO₂ levels.  As with all our sensors, data is relayed by our gateway over the internet in real time and can be viewed from any web browser.  CO₂ is an excellent indicator of how well a building's HVAC system is balancing/mixing in outside air.  Too much and it wastes energy, too little and the air is uncomfortably stale.

• Range 0-2000 PPM with resolution down to 1 PPM
• Accuracy - At 72°F (22°C) when compared against a certified factory reference ± 40 ppm + 3% of reading
• Temperature Dependence - 0.2% FS per °C
• Stability - < 2% of FS over life of sensor (15 year typical)
• Non Linearity - < 1% of FS
• Pressure Dependence - 0.135 of reading per mm Hg
• Calibration Interval - Calibration not required
• Response Time - < 2 minutes for 90% step change typical
• Warm up time - < 2 minutes (operational), 10 minutes (maximum accuracy)
• Operating conditions - 32°F to 122°F (0°C to 50°C), 0 to 95% RH, non condensing
• Over The Air updates of
• Firmware
• Configuration, including sample period (ie time between samples)
• Powered from AC adapter, 100-240 VAC in, 3.3 VDC out
• data can be graphed against data from any other OmniSense sensor or sensor(s)
• alarm emails when measured  CO₂ value exceeds high or low thresholds or returns to normal range.
• FCC/CE approved
• Automatic Background Logic, or ABC Logic, is a patented self-calibration technique that is designed to be used in applications where concentrations will drop to outside ambient conditions (approximately 400 ppm) at least 3 times in a 14 day period, typically during unoccupied periods.
• Compact and wireless makes for an easy installation.
