When people talk about multiple sensor system and the IoT they are describing multiple sensors monitoring a system be it a body of water, a manufacturing process etc.
Traditional chemical sensors, such as the glass barrel pH sensor, do not translate well into multiple sensor networks. This is because traditional sensors were originally designed for lab applications, where low cost and robustness were not considerations alongside functionality and accuracy.
At ZP we know that when you combine electrochemical sensing technology with low cost manufacturing principles you are able to manufacture a sensor with the right cost and functionality.
At ZP we have an extensive range of sensors, where the fundamental technology and manufacturing principles makes them perfect for those working on sensor network products.
