Abstract
An apparatus including first and second sensor elements, the first sensor element includes a first sensor material. The second sensor element includes a second sensor material. The first sensor material is configured such that an electrical property of the first sensor material is dependent upon the temperature of the environment in which the first and second sensor elements are located. The second sensor material is configured such that the same electrical property of the second sensor material is dependent upon the relative vapor pressure of a fluid in the environment in which the first and second sensor elements are located, the respective temperature and fluid relative vapor pressure dependencies of the first and second sensor materials allowing the temperature and fluid relative vapor pressure of the environment to be determined based on combined measurements of the electrical property of the first and second sensor materials in the environment.
