AECB News : Omnisense Remote Monitoring System/S-19 CO2 Sensor Available

omn

The AECB has negotiated an ongoing rate of benefit to members and can offer the Omnisense remote monitoring system at significantly preferential terms to AECB members for projects that would benefit from environmental condition monitoring.  The Omnisense system is a web-based remote monitoring system for buildings that measures relative humidity, temperature and moisture level. Currently members who have taken up this offer are monitoring various internal wall insulation constructions, insulated suspended timber floors, conditions within brickwork that has been externally insulated, etc

S-19  CO2 Sensor Available

We currently have an Omnisense S-19 Wireless CO2 sensor available which we are offering to AECB members on a first come first served basis.  The sensor has been used for testing purposes by Andy Simmonds and we are therefore offering this sensor for sale at the discounted price of £295 (exc VAT) plus P&P (usual price £334.80 exc VAT).

S-19 CO2 Sensor Description

The Omnisense 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.

•             Over The Air updates of

o             Firmware

o             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.
