PH Sensor Module PH Value Detection Detect Regulator Module Monitoring Control Meter Tester for STM32

Description: This sensor is low in price, easy to use, high in measurement accuracy, and can directly output 0~5V or 0~3V analog voltage signals.The pH of the solution (pH) is an important property of the solution. Industrial grade PH transmitters are expensive; the PH test pens on the market are mature products that cannot be used for secondary design development; P composite electrodes output mV-level voltage signals, and the microcontroller cannot directly identify and process them. Based on these conditions, we have designed this.
