Wireless digital thermometer

Abstract

The invention provides a wireless digital thermometer which comprises a transmitting circuit and a receiving circuit, wherein the transmitting circuit comprises a temperature sensor; the output end of the temperature sensor is connected with the input end of a first singlechip microcomputer, and the output end of the first singlechip microcomputer is connected with a wireless transmitting module; the receiving circuit comprises a wireless receiving module; the output end of the wireless receiving module is connected with the input end of a second singlechip microcomputer, and the output end of the second singlechip microcomputer is connected with a display module; the temperature sensor transmits a measured digital temperature signal to the first singlechip microcomputer for processing; then the wireless transmitting module transmits a wireless signal, the wireless receiving module receives the signal, the second singlechip microcomputer processes the signal, and then the display module is driven to perform digital temperature display, so that temperature measurement and wireless transmission can be performed, and long-distance intelligent monitoring is realized. The wireless digital thermometer has the characteristics of accuracy measurement, high sensitivity and wire application range.

Description

technical field [0001] The invention relates to a thermometer, in particular to a wireless digital thermometer. Background technique [0002] There are many kinds of thermometers commonly used in daily life, such as mercury thermometers, alcohol thermometers, kerosene thermometers, etc. Most of them are made according to the principle of thermal expansion and contraction of liquid or gas, but they are not suitable for some people who need accurate temperature measurement and remote monitoring. There are certain limitations when used in certain occasions. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to propose a wireless digital thermometer, which can measure and wirelessly transmit the temperature, realize remote intelligent monitoring, and has the characteristics of accurate measurement, high sensitivity and wide response range. [0004] In order to achieve the above obje...
