PH4502C PH Value Detection Water/Liquid Sensor Module without Electrode Probe
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 …
