The field of sensoring

• Sensors

• Sensor systems (netwerk)

• Data processing (big data)

The perfect sensor system

• Measures everything• Everywhere• Online• Cheap• Processes it’s data• Converts the signal in understandable

The dilemma in real life

• 1 expensive sensor which measureseverything

• Many cheap sensors which measureeverywhere

5125

Most wetsus sensor development

• Early warning systems

• Respond to a class of compounds rather than to a single substrate

• Fingerprinting

• Online
