Abstract:
In this work, a low cost automatic sensing system is proposed to detect ‘synthetic milk’, which has been reconstructed after adulterating the milk with ‘liquid-whey’. The constant-phase angle (CPA) based sensor detects the synthetic milk and a micro-controller based circuit drives a stepper motor to close the valve installed at the outlet of the milk supply line to prevent mixing. The sensor is stick type, rigid and hence it is easy to mount. The electrodes of the sensor are coated with polymethyl methacrylate (PMMA) film, which makes it bio-compatible and suitable for the application
