Description

Technical Field

[0001] This utility model relates to the field of sensors, specifically to a duct temperature and humidity sensor. Background Technology

[0002] Sensors are very common electronic components. Temperature and humidity sensors, as the name suggests, are sensors that measure or detect temperature and humidity in one or more environmental conditions. In existing technology, sensors include a housing, a circuit board, and a sensing element. The circuit board is housed within the housing, while at least a portion of the sensing element extends outside the housing, exposing it to the detection environment. The sensing element transmits the detected temperature and humidity data to the circuit board. However, the sensing elements in these existing sensors are short, limiting their applicability to relatively spacious environments. They are ineffective in confined spaces, such as detecting temperature and humidity in air ducts, where current sensors struggle.

[0003] In addition, existing sensors are complex in structure and cumbersome to install. Therefore, there is a need to invent a sensor that can detect narrow environments such as air ducts, while also being simple in structure and easy to install. Summary of the Invention

[0024] Please refer to Figure 1-3 This application provides a duct temperature and humidity sensor (hereinafter referred to as "the sensor"), which includes:

[0025] The housing 1 includes a cover plate 11 and a bottom shell 12, wherein the cover plate 11 is pivotally connected to the bottom shell 12, thereby allowing the cover plate 11 to pivot relative to the bottom shell 12 to open or close the bottom shell 12; the bottom shell 12 has an installation chamber 120.

Thus, by bolts or screws, the connecting piece 63 is connected to a support plate or support object in the environment to be measured, thereby fixing the entire sensor in the environment to be measured.

[0032] In some embodiments of this application, please refer to Figure 1-3 The fixed sleeve 61 has a second external thread 611 at one end, and the tightening wheel 62 has a second internal thread in the second mounting through hole 620.
