The all-round technology for a healthy indoor climate -

The new OCCULOG® VOC wall sensor measures air quality and humidity and is also a temperature controller. The air quality is determined on the basis of the organic volatile substances (VOC) in the air or CO2 eq. One status LED each indicates the current status of the air quality and humidity in the traffic light colours red, yellow and green. Of course, the measured values can be used ...

Detection of hazardous volatile organic compounds (VOCs ...

2016-11-01· The selectivity, sometime also defined as cross sensitivity, can be defined by an interfering ratio as: (5) K = S A / S B where S A and S B are the responses of a sensor to the target VOC and an interfering VOC, respectively, for equivalent concentrations . When the interfering ratio tends to one, the sensor shows no selectivity because the responses to the different compounds become comparable.

Using the BAPI VOC Sensor D27 -

BAPI’s VOC sensor offers the best of both worlds. It allows for ventilation based on occupancy as well as air contaminants. The BAPI unit does this because it has been optimized for DCV. Using a calibration algorithm, the sensor value is converted to an output with a high correlation to a CO2 level. This lets you use Ashrae’s more popular and straight forward occupany-based VRP schedule ...

The use of a VOC Sensor to Measure Freshness of Fruits

The Figaro TGS 2620 VOC Sensor was used to measure the VOC concentration within the sample. The VOC sensor is comprised of a metal-oxide semiconducting layer with an alumina substrate of a sensing chip. The VOC sensor was connected in parallel with a load resistor, as per the Figaro specifications [9]. The Arduino Nano microcontroller was
