Title of the Innovation: Sea Surface Temperature sensor
Brief About Innovation
Negative Temperature Coefficient (NTC) Sea Surface Temperature SST sensor is developed for Ocean observation applications. The NTC sensing element is used in an advanced manner in developing temperature sensor for the measurement of sea surface layer temperature. This is the first of its kind as sensor for sea surface temperature (SST) and sea subsurface layer temperature (SSST) measurement is concerned. The Steinhart–Hart equation and coefficients is applied on each sampling to zero down the error components involved in temperature measurements which is corresponding to the nonlinear functionality of NTC element. In-house developed SST sensor and sensor array is calibrated and extensively tested in laboratory conditions.
A high precision and fast responding NTC thermistor element is employed as a temperature sensor. The data acquisition is made of low power, reconfigurable, programmable system on chip PSOC manufactured by Cypress semiconductor. The nonlinearity of the thermistor sensors are corrected with Stein-Hart and Hart model and calibration coefficients.
