Particle or pollen sensor and sensing method
A particle or pollen sensor comprises an array of relative humidity sensors. A change in relative humidity is representative of a particle or pollen in contact with one or more of the sensors. A size and/or shape of a particle or pollen in contact with one or more of the sensors is optionally also determined based on the number and/or configuration of sensors. From this information, a particle or pollen type is determined.
