PH Sensor Module

   This PH sensor Module consists of PH sensor also called as PH probe and a Signal Conditioning Board which gives an output which is proportional to the PH Value and can be interfaced directly to any Micro-controller.

The pH sensor components are usually combined into one device called a combination pH electrode. The measuring electrode is usually glass and quite fragile. Recent developments have replaced the glass with more durable solid-state sensors. The preamplifier is a signal-conditioning device. It takes the high-impedance pH electrode signal and changes it into a low impedance signal which the analyzer or transmitter can accept. The preamplifier also strengthens and stabilizes the signal, making it less susceptible to electrical noise.
