Humiture sensor

Abstract

The invention discloses a humiture sensor. The humiture sensor comprises a data acquisition unit, a control processing unit, a communication unit and a reception unit, wherein the data acquisition unit comprises multiple temperature sensors and multiple humidity sensors, the data acquired by the data acquisition unit is transmitted through a middleware adapter to a wireless communication module, the control processing unit is used for receiving a voltage signal of a detection unit, converting the voltage signal into a digital signal and storing the digital signal, the communication unit is used for sending the signal of the control processing unit to the reception unit in a wireless mode, the reception unit is used for receiving the signal of the communication unit, and the wireless communication module comprises communication units of multiple frequency bands. According to the humiture sensor, full passive components such as inductors and capacitors form the integrated temperature and humidity sensor, as all the components are passive devices, the humiture sensor can operate in high-temperature, low temperature and high pollution serious environments; the humiture sensor is manufactured by employing the CMOSMEMS technology, properties of low consumption, good consistency and low cost are realized, and the humiture sensor is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of temperature and humidity measurement, in particular to a temperature and humidity sensor. Background technique [0002] Traditional temperature and humidity measurements generally use thermocouples, thermistors, and separate temperature and humidity sensors. However, such components are easily restricted by the measurement site and the environment, and their performance will degrade due to the influence of the environment during long-term use. Regular inspection and replacement are required. Moreover, when the signal lines are transmitted over long distances, they are prone to interfere with each other, and the wires are not easy to lay. , which brings great inconvenience to the practical application. [0003] At the same time, in the existing wireless sensor network, the wireless communication module is directly installed on the collection node, and the collected data is directly sent to the terminal computer for...

However, such components are easily restricted by the measurement site and the environment, and their performance will degrade due to the influence of the environment during long-term use. Regular inspection and replacement are required. Moreover, when the signal lines are transmitted over long distances, they are prone to interfere with each other, and the wires are not easy to lay. , which brings great inconvenience to the practical application

[0003] At the same time, in the existing wireless sensor network, the wireless communication module is directly installed on the collection node, and the collected data is directly sent to the terminal computer for processing. In this way, the amount of collected data is very large, which brings a great load to the terminal computer. , and many of these data are useless data, wasting computing resources
