Abstract

The invention relates to an integrated sensor which comprises a circuit board, temperature sensors, a humidity sensor, a carbon dioxide sensor and digital signal processing circuits are arranged on the circuit board, and the temperature sensors, the humidity sensor and the carbon dioxide sensor are connected with one digital signal processing circuit respectively to form an integral structure. Due to the integrated design technology, the temperature sensors, the humidity sensor, the carbon dioxide sensor and the digital signal processing circuits are designed to a module, nonlinear correction and temperature compensation of signals output by the sensors reduce influences of the outside world on the signals of the sensors, stability is improved, and production cost and installation and maintenance cost are reduced. The integrated sensor has the advantages of being simple in structure, small in size, light in weight, long in service life and the like. The integrated sensor can be widely applied to data collection of different types of agricultural greenhouse environments and intelligent agricultural production.

Description

technical field [0001] The invention relates to the field of sensors, in particular to an integrated sensor for collecting temperature, humidity and carbon dioxide. Background technique [0002] A sensor is a detection device that can feel the measured information, and can convert the detected information into electrical signals or other required forms of information output according to certain rules, so as to meet the needs of information transmission, processing, storage, display, recording and control requirements. It is the first link to realize automatic detection and automatic control. [0003] Sensing technology——study the comprehensive technology of the material, design, process, performance and application of sensors. Sensing technology is an edge technology, which involves physics, mathematics, chemistry, and involves the research and development of its sensitive components. In addition to the research and development of its chip, it should also attach great impo...
