A Smartphone-based Thermal Imaging Sensor for Temperature Measurement of Animal Groups

Animal body surface temperature abnormality is highly correlated with animal physiological abnormalities and epidemic diseases. In animal groups, the conventional local thermometry is always stuck in limitations like large workload and large temperature error induced by animal restraint stress reaction, etc. A fast surface temperature measurement system carrying a smartphone-based miniature non-refrigeration IR thermal imaging temperature sensor for animal groups was developed in this research. A thermostat-based internal calibration method was established to tackle the temperature drift of the thermal core, and implement the real-time calibration of the temperature measuring errors caused by the temperature response drift of the detector.
