Portable multipath automatic instrument for detecting moisture, air pressure and temperature of soil

Abstract

The invention discloses a multi-purpose portable automatic detecting instrument for soil moisture, air pressure, and temperature, which comprises a soil moisture content signal detection input conversion portion, air pressure signal detection input conversion portion, temperature signal detection input conversion portion, push-button portion, graph dot matrix mode liquid crystal display portion, high capacity nonvolatile storage portion, real time clock portion, power supply management portion, communication interface portion and microprocessor portion, wherein the sensor and the observing and control portion form a set of portable temperature and pressure detection and recording apparatus.The advantages of the apparatus by the invention are high measurement accuracy and low power consumption, it is suitable for the on-site data acquisition in various industrial and scientific research fields.

Description

1. Technical field [0001] The invention relates to a portable multi-channel soil moisture, air pressure and temperature automatic detector used in industrial measurement and control, agricultural and ecological science and technology research, which is suitable for measuring soil water content, air pressure and temperature in soil characteristic measurement. 2. Background technology [0002] The existing pressure and temperature detection devices in industrial applications are all secondary instruments that detect pressure or temperature separately, and mainly have the following shortcomings: the function is relatively single, and they do not have a large amount of data storage and automatic recording functions, and do not have data Chinese characters Display man-machine interface and communication interface, do not have low-voltage and low-power portable functions, or do not have the above functions at the same time. These defects greatly limit the application of existing p...
