Wireless temperature sensor chip

Abstract

The invention discloses a wireless temperature sensor chip. The wireless temperature sensor chip mainly solves the problems that in the prior art, the wireless temperature sensor chip which is safe, reliable and low in power consumption is lacked, and technological development needs cannot be met. The wireless temperature sensor chip comprises a power source management unit, a temperature sensor unit, a band-gap reference unit, an ADC unit, an electrification detection unit and a radio frequency receiving and transmitting unit, the power source management unit, the temperature sensor unit, the band-gap reference unit, the ADC unit, the electrification detection unit and the radio frequency receiving and transmitting unit are all integrated together, the power source management unit supports power source input of a front end self energy taking device and external power source input, and a high voltage resisting LDMOS tube is designed to be of an LDO structure. Through the scheme, the wireless temperature sensor chip achieves the aims of being simple in structure, ingenious in design, stable in work and high in cost performance, and has high practical value and promotional value.

Description

technical field [0001] The invention relates to a wireless temperature sensor chip. Background technique [0002] After entering the 21st century, self-energy wireless intelligent temperature sensors are moving towards high-tech directions such as high precision, multi-function, bus standardization, high reliability and security, development of virtual sensors and network sensors, and development of single-chip temperature measurement systems. develop. [0003] Traditional wireless temperature sensors are generally powered by batteries. Although the energy storage density and service life of batteries continue to improve with technological progress, there are still some insurmountable energy supply defects, such as limited energy supply life, repeated charging, volume and quality. Larger, etc., can not fully meet the development requirements of wireless sensor networks. With the wide application of wireless sensor networks, the number of nodes is getting larger and larger,...
