Temperature humidity gauge based on MSP 430 singlechip

Abstract

The invention relates to a temperature humidity gauge based on a MSP 430 singlechip. The measurement gauge in prior has greater volume and has incompatible mechanical parts and electronic control devices. The invention comprises a control module, a temperature module, a humidity module, a RS232 communication module, a RS 485 module, an alarm module, a power supply module and a power supply voltage measuring module. The power supply module supplies working voltage for the control module, the temperature module, the humidity module, the RS 232 communication module, the RS 485 communication module and the power supply voltage measuring module; the control module is respectively connected with the temperature module and the humidity module through signals, and the control module is communicated with an upper host computer through the RS 232 communication module and the RS 485 communication module. The power supply voltage measuring module is connected with the A / D of the power supply module through signals. The alarm module is respectively connected with the RS 232 communication module, the RS 485 communication module and the control module through signals. The temperature humidity gauge based on a MSP 430 singlechip has low power consumption, high accuracy and can receive analog and digital signals.

Description

technical field [0001] The invention belongs to the field of measurement and sensing, and in particular relates to a temperature and humidity meter based on an MSP430 single-chip microcomputer. Background technique [0002] Temperature and humidity are closely related to people's life and industrial production, and we need to know the exact value of both in many occasions. How to measure them accurately and conveniently, many methods have been proposed, such as mercury thermometers for measuring body temperature, alcohol thermometers, kerosene thermometers for room temperature, thermocouples for industrial sites, and infrared non-contact for measuring high temperatures. Temperature measurement technology, temperature measurement technology based on color CCD three primary colors and laser temperature measurement technology. The above-mentioned temperature measurement technologies have their own advantages and disadvantages. As far as the temperature measurement technologies...
