NOVELTY - The utility model relates to the technical field of temperature sensor, specifically to a temperature sensor based on graphene material, comprising a shell, the inner part of the shell is provided with a graphene resistor, the top end of the shell is fixedly installed with an end cover, the end cover is provided with multiple through holes uniformly distributed, the lower end of the shell is fixedly mounted with a radiating ceramic sheet located below the graphene resistor, the bottom surface of the radiating ceramic sheet is connected with several uniformly distributed radiating fins, and the bottom end of the radiating fin extends to the outer side surface of the bottom end of the shell, the bottom end of the graphene resistor is connected with two groups of pins, and two groups of pins pass through the radiating ceramic sheet and extend to the outside of the shell; The utility model uses graphene material as the temperature measuring resistance, graphene material has a thermal conductivity of up to 5300W/ (m *K), so it has a very short response time to the temperature, so when the temperature of the test environment is changed, The temperature sensor taking graphene material as resistance can quickly detect the current temperature, so as to improve the temperature measuring efficiency.
