Electronic device for detecting an environmental quantity
A device for the on-field mapping of the spatial distribution of environmental parameters (temperature, relative humidity, specific humidity, light, concentration of pollutants…). The portable electronic psychrometer consists of: Unit A) psychrometer/transmitter consisting of a chassis insulated, grip handle and base with screw coupling, equipped with sensors: dry bulb thermometer, wet bulb thermometer (connected to a water tank), barometer. Unit B) software technology (prototyped as an APP for iOS environment) which controls the device for the acquisition of the data and allows the operator to store, easily export, and process the data on the software.
The environmental data are acquired by positioning the unit (A) in correspondence of the points identified by a Cartesian grid XY (Z) virtually disposed in the space horizontally (plan) or vertically In the prototype, the unit-A is equipped with sensors for temperature and humidity mapping in museum environments, where the spatial distribution of these quantities is significant for the preservation of works of art. Unit-A can be held by the operator to map environmental values at head height, or grafted on a measuring rod, a rover, a flying drone or an airship to map values far from the ground both indoor/outdoor. It can be handled by the operator when it is required to map the environmental paramters at man-height. Otherwise, it can be fixed on a telescopic measuring rod, on a vehicle or on a drone when it is required to map the parameters at different heights or in places non-reachable by humans. The use of the pyschometer is limited to environments with T>8°C, limiting its outdoor usability in winter, in mountainous areas or at low latitudes.
- In the field of cultural heritage and is aimed at conservators and operators of preventive conservation, in the museum field;
- Biomedical, construction, industrial for the mapping of other parameters such as harmful contaminants or radiation and for emergency operation where it is not possible to intervene safely by the operator.
- Installation of sensors within an insulated chassis (Unit-A), with a handle that gives the operator a good grip and a base with screw coupling for the connection with other devices;
- Addition of wi-fi transmission between Unit-A and Unit-B for remote control;
- Creation of a specific software for Unit-B, prototyped as an APP for iOS environment, for Unit-A control and data gathering, within a Cartesian coordinate system.
