Abstract: We disclose herein a method for testing a batch of environmental sensors to determine the fitness for purpose of the batch of environmental sensors, the method comprising: performing a plurality of electrical test sequences to the sensor inputs of the batch of environmental sensors to measure electrical responses of the sensor outputs of the batch of environmental sensors; correlating the measured electrical responses from the batch of environmental sensors to predetermined environmental parametric ranges of at least one environmental sensor so as to define correlated electrical test limits; and determining the fitness for purpose of the batch of environmental sensors if the measured electrical responses are within the correlated electrical test limits.

Abstract: We disclose herein a method for heating a gas sensing material formulation on a microhotplate which comprises: a dielectric membrane formed on a semiconductor substrate comprising an etched portion; and the gas sensing material formulation being located on one side of the dielectric membrane. The method comprising: selectively heating the gas sensing material formulation using an infra-red (IR) heater located over the substrate, and controllably cooling the semiconductor substrate using a cooling baseplate provided under the substrate and using an insulating medium located between the substrate and the cooling base plate so that a gas sensing structure is formed on said one side of the dielectric membrane from the gas sensing material formulation.
