Info after payment:-Humid Scan Nano-Probeis a metal oxide – agar based nanosensor for real time moisture detection of a packaged perishable industrial products. It has a sensitive resistive chemical nanosensor made from a hybrid of metal oxide nanoparticles (NPs) and agar, designed for real-time moisture detection in packaged products. The sensor features a printed circuit board (PCB), a single-core wire, and a 2% agar nanocomposite combined with nanoparticles. The fabrication process involves designing and arranging electrodes on the PCB, amalgamating the NPs/agar nanocomposite, coating the PCB with this material, and performing an etching process to remove unwanted copper. The result is a highly sensitive resistive sensor that detects moisture through changes in resistance, ensuring the product’s moisture levels are monitored accurately during storage and packaging.
