A multifunctional environmental sensor device is connectable to a terminal of an electronic device for use. The sensor device includes a substrate, a plurality of different types of components mounted on the substrate and including at least a light emitter and an illuminance sensor, and a wiring pattern located on a surface of the substrate and including a contact to be in contact with the terminal of the electronic device. The light emitter is mounted on a surface of the substrate opposite to a surface of the substrate on which the illuminance sensor is mounted.

Air quality measurement system, method and apparatus are described. The air quality measurement system is also referred to as air constituent measurement system. Various air-quality parameters such as, for example, particulate matter, SO2, NO2, CO, O3, H2S, CO2, HCL, NH3, CH4, VOC etc. can be measured.

A 3D gas chromatography (GC) column development is possible by assembly of two parts each being substrates formed by gas tight materials. One part may be a silicon substrate with a snake shaped flow channel structure and the other part may be a glass plate. Both are coated with a column packing comprising polubutadiene, which is also able to glue or bond both parts together, thereby sealing the flow channel, thus forming a GC column. The column packaging can be composed in all kinds of polarity from very hydrophobic till very hydrophilic. In this way the column packing can be tuned on resolution for particular molecules which are interesting to detect, e.g. Octane. The invention is advantageous for micro GC columns.

A monitoring device (1) for a system for generating medical compressed air includes a measured air line (3) removing compressed air from a compressed air supply line downstream of a compressed air conditioning unit. A sensor (2) generates a measured signal as a function of a property of the compressed air fed through the measured air line. A humidifier (8) humidifies the compressed air upstream of the sensor. An output unit (12) outputs information about the property of the compressed air to a user on the basis of the measured signal. A tap (4) removes compressed air and an actuator (5) changes a volume flow and/or mass flow of the compressed air, which volume flow and/or mass flow prevails in the measured air line. The actuator is inserted into the tap in a measuring mode and is removed from the tap in a compressed air removal mode.

A monitoring system for monitoring an environment and generating data in response to the presence of at least one chemical hazardous to human health in the environment. The monitoring system is configured to communicate the data to an associated personal communication device or the like for processing. The monitoring system can be in the form a selectively attachable component.
