Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to an indoor temperature sensor. Background Art

[0002] A temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. The temperature sensor is the core part of a temperature measuring instrument. There are many varieties of temperature sensors. According to the measurement method, they can be divided into two categories: contact and non-contact. According to the sensor material and electronic component characteristics, they can be divided into two categories: thermal resistors and thermocouples. In greenhouse crop cultivation, temperature sensors are needed to detect the indoor temperature. However, most of the existing temperature sensors are fixedly installed somewhere in the greenhouse during use, resulting in a limited detection range and the inability to detect the temperature of environments at different heights. The practicality is poor. Secondly, since most of the existing temperature sensors are fixedly installed, it is not convenient to disassemble them, and it is not convenient to inspect and maintain the temperature sensors. Therefore, an indoor temperature sensor is proposed. Utility Model Content
