Water temperature sensing device adopting woven net-shaped structure

The invention relates to a temperature sensing element used for directly measuring water temperature, specifically to a water temperature sensing device adopting a woven net-shaped structure. The water temperature sensing device includes a flexible carrier component, a sensing element and an electrode. The sensing element is rectangular net-shaped, is flatly laid in a middle part of the flexible carrier, and is connected with an external circuit through an electrode. When temperature changes, the shape of the flexible carrier component changes with the temperature, the sensing element generates feedback, and resistance changes, thereby achieving the purpose of measuring temperature. The water temperature sensing device does not directly contact with water flow, stable encapsulation of a flexible carrier material can well protect the sensing element, slippage of an overlapping position of the net-shaped structure in the sensing element can enable resistance variation to increase, thereby greatly improving stability and sensitivity, and the water temperature sensing device is a temperature sensing device capable of being directly used for measuring water temperature.
