Small-volume wireless temperature measuring module powered by battery

Abstract

The invention belongs to a small-volume wireless temperature measuring module powered by a battery, which is characterized in that: pins 1-5 of an MSP430 ultralow-power-consumption processor (4) are respectively connected with pins 1-5 of a programming interface (2); pins 6,7 of the MSP430 ultra-low-power-consumption processor are connected with pins 1,2 of a configuration interface (1); a pin 9 of the MSP430 ultra-low-power-consumption processor is connected with a pin 1 of a DS18B20 digital temperature sensor (8); a pin 10 of the MSP430 ultra-low-power-consumption processor is connected with a pin 1 of a MOS temperature sensor power supply controller (7); pins 11-16 of the MSP430 ultra-low-power-consumption processor are respectively connected with pins 6-1 of a QRF-0600Zigbee wireless module (6); a pin 17 of the MSP430 ultra-low-power-consumption processor is connected with a pin 2 of a PMOS module power supply controller (5); a pin 18 of the MSP430 ultra-low-power-consumption processor is connected with an node of a lithium battery (3), a pin 1 of the PMOS module power supply controller (5) and a pin 2 of the PMOS temperature sensor power supply controller (7); and a pin 8 of the MSP430 ultra-low-power-consumption processor is grounded. The small-volume wireless temperature measuring module has advantages of: small volume, low power consumption, long maintenance-free operation time and convenient wiring and mounting. The small-volume wireless temperature measuring module can be mounted at high-voltage places, narrow places and rodent places. High production efficiency is realized. Manpower, material resource and accident are reduced.

Description

technical field [0001] The invention belongs to electrical components, in particular to a battery-powered small-volume wireless temperature-measuring module. Background technique [0002] In the traditional intelligent digital temperature measurement system, the temperature measurement probe is usually installed in a wired / active way, such as the wired connection between PT100 / PT1000 and the host, and the multi-point wired connection method of DS18B20. This wired installation method cannot be used in places where wiring is not suitable for high voltage, narrow, rodent damage, etc., and installation and debugging are troublesome. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies and provide a battery-powered small-volume wireless temperature measurement module that is powered by a lithium sub-battery, an ultra-low power consumption microprocessor, a low power consumption Zigbee wireless module, ...
