Research on High Precision pH Sensing Device Based on Cloud Platform Service

Abstract : This project tries to design a wireless intelligent pH sensor to monitor the pH value of nutrient solution in real time by using the analog front circuit LMP91200, microprocessor STM32F103c8t6 and WiFi module. The experiment shows: this equipment has a high accuracy, can be 0.01; it can access business cloud services platform to achieve the functions like accurate acquisition and calibration of pH value, Interactive with cloud platform through WiFi Networks; APP and PC for the remote measurement is stable, after 12 h of testing there is no packet loss phenomenon; Because of high uploading speed, in 5 s it can complete the device networking and upload, besides, the cloud services have changed the traditional way of nutrient solution measurement.
