Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, and particularly relates to a wall-mounted temperature and humidity sensor. Background Art

[0002] Temperature and humidity sensors can convert the two physical quantities of temperature and humidity into electrical signals that are easy to measure and process. This type of sensor is usually equipped with hygroscopic and thermal elements to measure the temperature and humidity in the environment. Temperature and humidity sensors mostly use integrated temperature and humidity probes as temperature measuring elements. The collected temperature and humidity signals are processed by a series of circuits, such as voltage stabilization and filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection, etc., and converted into current signals or voltage signals that are linearly related to temperature and humidity. In addition, some temperature and humidity sensors can also output interfaces such as 485 or 232 through the main control chip, and wall-mounted temperature and humidity sensors are temperature and humidity sensors that are mounted by hanging.

[0003] A Chinese patent with publication number "CN220398609U" discloses a temperature and humidity sensor, which includes a temperature and humidity sensor body, a protective plate, an air blower, a display screen, a dust scraper, a control button and an audible and visual alarm. A protective plate is installed on the top of the temperature and humidity sensor body, and an air blower is installed on the bottom of the protective plate. The front surface of the temperature and humidity sensor body is embedded with a display screen and a control button, and the display screen is located above the control button. The air outlet of the air blower faces the display screen, and a dust scraper is installed on the surface of the display screen. An audible and visual alarm is installed on the bottom of the temperature and humidity sensor body. A control host is arranged inside the temperature and humidity sensor body, and the air blower, display screen, dust scraper, control button and audible and visual alarm are all electrically connected to the control host.

[0004] However, this sensor still has some shortcomings. When the sensor is mounted on the wall, the previous wall-mounting method is to screw bolts into the wall or insert a fixing rod into the wall. When the sensor needs to be removed for maintenance, the user needs to pull the fixing parts of the sensor out of the wall, which is not convenient for disassembly and will cause certain damage to the wall. At the same time, it also reduces the stability of the secondary fixed sensor position. Utility Model Content
