(Title: Based on wireless Lora communication, remote acquisition and output of 0~5v, 0-10V, 0~20ma, 4-20mA analog signals and switching signals are realized. Label: Temperature and humidity acquisition, voltage and current acquisition, weighing acquisition, pull pressure acquisition, concentration acquisition, analog signal acquisition. Document introduction: This paper explains how to realize remote acquisition and output 0~5v, 0-10V, 0~20ma, 4-20mA analog signals and switching signals based on wireless Lora communication. Through this scheme, the analog signals such as temperature and humidity, voltage and current, weighing, pull pressure, concentration and so on can be collected by wireless remotely, and the analog and switching signals can be output in reverse.)
