Embodiment Construction

[0023] Such as figure 1 To the wireless pressure sensor based on LoRa technology in the weighing electronic scale shown, including a power supply module, a pressure acquisition module, a LoRa data sending module, a LoRa data receiving module and an instrument, the LoRa data sending module and the LoRa data receiving module can be connected Two-way transmission of data.

[0024] The power module, pressure acquisition module, LoRa data sending module and LoRa data receiving module and instrument are located in two different places. The power module, pressure acquisition module, and LoRa data sending module are all built in the electronic scale. The acquisition module is electrically connected to the LoRa data transmission module, and the pressure acquisition module is also connected to the LoRa data transmission module. The pressure acquisition module uses the change of the piezoresistor of the arch bridge circuit to collect the pressure of the object called by the electronic sc...

Abstract

The invention discloses a wireless pressure sensor based on a LoRa technology in an electronic weighing device for weighing, which comprises a power supply module, a pressure acquisition module, a LoRa data transmission module, a LoRa data receiving module and an instrument, wherein the power supply module is electrically connected with the pressure acquisition module and the LoRa data transmission module respectively, the pressure acquisition module is also connected with the LoRa data transmission module, the pressure acquisition module is used for acquiring the pressure of an object weighted by the electronic weighing instrument and transmitting the acquired pressure signal to the LoRa data transmission module, the LoRa data transmission module transmits the received pressure signal tothe LoRa data receiving module in a wireless transmission mode, the LoR data receiving module transmits the received pressure signal to an instrument, and finally, the weight of the object is diaplayed after the pressure signal is processed by the instrument. The sensor has the advantages of low cost, low transmission power consumption and long transmission distance.

Description

technical field [0001] The invention relates to wireless communication equipment, in particular to a wireless pressure sensor based on LoRa technology in weighing electronic scales. Background technique [0002] Nowadays, the rapid development of economy and technology has brought convenience to our life in all aspects. The research and development and use of sensors are playing an increasingly important role in industrial production. The realization of wireless transmission and intelligent applications of sensors has become an important part of today's communication field. hotspots. [0003] At present, most of the sensors still rely on wired cables to transmit data to the outside, and the cost is high. At the same time, the cables will be affected by factors such as humidity, temperature, and electromagnetics. great difficulty. Therefore, the use of wireless sensors for long-distance data transmission has become a necessary choice. [0004] In addition, the sensor uses ...
