Description: A pH biosensor is a device that measures the acidity or alkalinity of a solution, providing crucial data for various applications in fields such as biotechnology, medicine, and agriculture. This type of sensor combines a pH-sensitive electrode with a transduction system that converts the electrochemical signal into a digital reading. pH biosensors are highly sensitive and can detect minimal changes in pH levels, making them ideal for monitoring biological and chemical processes in real-time. Their integration with IoT technologies allows for data transmission to cloud platforms, facilitating analysis and decision-making based on accurate and up-to-date information. The ability of these sensors to operate continuously and remotely makes them valuable tools for process automation and quality control in various industries. Additionally, their compact design and ease of use make them accessible for both research laboratories and industrial applications, where constant pH monitoring is essential to ensure product quality and safety.
