Description
Technical field
The utility model relates to damp-warm syndrome sensor, particularly relates to a kind of digital damp-warm syndrome sensor based on SHT1X.
Background technology
Sensor (transducer/sensor) is a kind of pick-up unit, measured information can be experienced, and can will detect the information experienced, the information being for conversion into electric signal or other desired forms according to certain rules exports, to meet the requirements such as the transmission of information, process, storage, display, record and control.It is the primary link realizing automatically detecting and automatically controlling.Such as temperature and moisture sensors is widely used in fields such as Heating,Ventilating and Air Conditioning (HVAC), automobile, weather station, household electrical appliances, physiotherapys.
Temperature sensor (temperature transducer) refers to can experience temperature and the sensor converting usable output signal to.Contact and contactless two large classes can be divided into by metering system, be divided into thermal resistance and thermopair two class according to sensor material and electron component characteristic; Humidity sensor refers to can experience humidity and the sensor converting usable output signal to.Be made up of humidity-sensitive element and can be divided into the large class of resistance-type, condenser type two according to principle of work.
Traditional humidity and temperature sensor function is independently, and output is easily subject to various environmental interference with analog signal output.Therefore need a kind of new sensor of design can simultaneously measures ambient temperature and humidity, and digital quantity can be exported based on single-chip microcomputer, exempt from the Temperature Humidity Sensor that disturbs.
Summary of the invention
The utility model is to solve above-mentioned deficiency, provides a kind of digital damp-warm syndrome sensor based on SHT1X.
Above-mentioned purpose of the present utility model is realized by following technical scheme: a kind of digital damp-warm syndrome sensor based on SHT1X, it is characterized in that: comprise housing, humidity sensor, temperature sensor, AD signal converter, checksum memory, SHT1X single-chip microcomputer is provided with in described housing, described humidity sensor, temperature sensor, checksum memory are all connected with AD signal converter, AD signal converter is connected to SHT1X single-chip microcomputer again, and SHT1X single-chip microcomputer is connected with data display screen and electric supply installation.
Described humidity sensor and temperature sensor adopt condenser type condensate hygrometric element and an energy gap type temperature element composition respectively, be used for the temperature and humidity signal experienced in environment the temperature and humidity physical signalling recorded is changed into voltage or current signal, the voltage of gained or current signal transfer are to AD signal converter; Described AD signal converter has analog conversion function, becomes checksum memory and SHT1X single-chip microcomputer can be other binary numbers voltage and current signal by the method migration of integration or Approach by inchmeal.
Described checksum memory is the storer pre-setting calibration factor, can verify pass to SHT1X single-chip microcomputer more subsequently to the digital signal in AD signal converter.
Described SHT1X single-chip microcomputer processes to the digital signal after verification and calculates the function realizing calculating and exporting.
The utility model advantage is compared with prior art:
(1) condenser type hygrometric element and can gap type temperature element and the A/D converter of 14 and serial interface circuit realize on the same chip seamless link have quality brilliance, super fast response, antijamming capability by force, cost performance pole advantages of higher.
(2) two-wire system serial line interface and internal reference voltage, makes the system integration become fast simple and easy.Extra small volume, extremely low power consumption.
(3) higher than general Temperature Humidity Sensor precision.
