Water temperature sensor installed in the car engine cylinder or the water jacket of cylinder cover，and direct contact with cooling water，used to detect the temperature of the cooling water.The water temperature sensor internal adopt negative temperature coefficient (NTC)thermistor composition(temperature lower, but the higher resistance,otherwise the lower resistance).  http://www.hongsean.com/
