Sensor device
A sensor device according to the present invention includes: a sensor element including a temperature-sensitive resistor; and a protective cover that protects the sensor element, wherein the sensor element has a shape extending long along one direction, and the protective cover surrounds a periphery of the sensor element with a plurality of support pillars extending obliquely with respect to a longitudinal direction of the sensor element. It is preferable that the plurality of support pillars intersect in a lattice-like manner.
1. A sensor device comprising:
a sensor element, which measures wind speed, including a temperature-sensitive resistor; and
a protective cover that protects the sensor element,
wherein the sensor element has a shape extending long along one direction,
wherein the temperature-sensitive resistor is formed along an entire circumferential direction about a centerline extending in the one direction, and
wherein the protective cover surrounds a periphery of the sensor element with a plurality of support pillars extending obliquely with respect to a longitudinal direction of the sensor element, allowing omni-directional wind speed detection in the circumferential direction.
2. The sensor device according to claim 1 , wherein the plurality of support pillars intersect in a lattice-like manner.
3. The sensor device according to claim 2 , wherein intersections where the plurality of support pillars intersect, deviate from a center of the sensor element in a side view at each of all angles to a circumferential direction.
4. The sensor device according to claim 1 , wherein a width of each of the support pillars is smaller than a longitudinal length of the sensor element.
5. The sensor device according to claim 1 , wherein a length from an outside to an inside of each of the support pillars is larger than a width of each of the support pillars.
6. The sensor device according to claim 1 , wherein each of the support pillars is formed so as to have a protrusion-shaped section in which a width gradually decreases from an inside to an outside.
7. The sensor device according to claim 1 , wherein the protective cover includes a storage unit in which a substrate supporting the sensor element is stored, in a lower end of the support pillars.
8. A sensor device comprising:
a sensor element, which measures wind speed, including a temperature-sensitive resistor; and
a protective cover that protects the sensor element,
wherein the sensor element is supported by a substrate,
wherein the temperature-sensitive resistor is formed along an entire circumferential direction of the sensor element, and
wherein the protective cover surrounds a periphery of the sensor element with a plurality of support pillars extending obliquely with respect to a direction in which the sensor element is placed as viewed from the substrate, allowing omni-directional wind speed detection in the circumferential direction.
