[0038] like Figure 1 and Figure 2 As shown, this embodiment provides a temperature and humidity monitor, including:

[0039] A housing and a circuit board inside the housing;

[0040] The circuit board includes a substrate and a main control chip 1 and a data monitoring element 2 arranged on the substrate. The main control chip 1 and the data monitoring element 2 are electrically connected, and the data monitoring element 2 sends monitoring data to the main control chip 1;

[0041] The substrate is provided with an L-shaped cutout, which forms a first mounting portion and a second mounting portion on the substrate. The data monitoring element 2 is arranged on the first mounting portion, and the main control chip 1 is arranged on the second mounting portion.

[0042] In implementation, the circuit board inside the housing may be a PCB circuit board, an FPC circuit board, or an FPCB circuit board, etc. The type of the circuit board is not limited in this embodiment.

[0043] like Figure 1 As shown, the first mounting part and the second mounting part are connected by only a shorter side. The first mounting part is actually equivalent to forming a "peninsula"-like structure on the second mounting part, and the data monitoring element 2 is arranged at one end of the first mounting part away from the second mounting part. This can, on the one hand, be more conducive to the contact between the data monitoring element 2 on the first mounting part and the external environment, so as to better collect data. On the other hand, it can also minimize the influence of the heat generated by the main control chip 1 on data collection, so as to make the temperature and humidity measurement more accurate.

[0044] In the temperature and humidity monitor provided in this embodiment, an L-shaped incision is set by specially processing the circuit board. The L-shaped incision can isolate the setting position of the data monitoring element 2 and the heat-generating main control chip 1. In this way, the heat generated by the main control chip 1 during operation will not easily interfere with the data monitoring element 2 for data collection through heat conduction. In addition, the main control chip 1 will also affect the surrounding humidity while generating heat.

The display screen can be used to display the results collected by the data monitoring element 2, and can also be used to display the parameters of the working process, such as current value and / or voltage value, etc. It can also be used to display time parameters. The time parameters can include the current time, and can also include the length of time that temperature and humidity monitoring has been performed.
