Digital temperature sensor with WIFI interface

Abstract

The invention discloses a digital temperature sensor with a WIFI interface, related to the field of temperature sensing and communication. The digital temperature sensor with the WIFI interface comprises a CC3200 wireless module terminal and a number of digital temperature sensors; the digital temperature sensor comprises a temperature sensor, a digital signal input and output terminal DQ, a powermodule VDD and a 64-bit ROM; the temperature sensor establishes a bus protocol with a host through the 64-bit ROM and ROM operation commands; and data communication between the DS18B20 and the host is realized after the protocol is established. A storage control logic module is connected to the 64-bit ROM and a temporary storage memory separately and transmits data to each other; and the temporary storage memory receives data from the temperature sensor, a high temperature register TH, a low temperature register TL, a configuration register CONFIG, and a signal from an 8-bit CRC generator; CC3200 chips are used to design a peripheral circuit and a RF wireless signal transmitting circuit for the CC3200 wireless module terminal; and the CC3200 wireless module terminal is connected to the bus interface of the digital temperature sensor through a bus cable. The digital temperature sensor with the WIFI interface can collect more data and has a wide range of applications.

Description

technical field [0001] The invention relates to the field of temperature sensing and communication, in particular to a digital temperature sensor with a WIFI interface, which is suitable for outputting temperature data and receiving commands. Background technique [0002] The temperature sensor is an important part in the temperature test process, and its accuracy directly affects the normal working condition of the measured object. In the rapid development of all walks of life in modern times, temperature data is also an important factor restricting the development, especially in manufacturing, medical, aerospace, mining, etc. At the same time, traditional sensors also have defects such as multiple cables and low load ratio. Common temperature sensors include thermistors, thermocouples, etc. Thermistors have long been popular because of their very small form factor, low cost, and high sensitivity. The downside is a limited temperature range and lack of industry standards,...

The downside is a limited temperature range and lack of industry standards, making replacement difficult

Thermocouples are ideal for monitoring extreme temperatures, but have poor accuracy and stability, and must be tested very accurately under controlled conditions. These are often common problems with analog sensors and cannot meet the accuracy level of the measurement system
