Example 6 :

According to the embodiment 1 or 2 or 3 or 4 or 5 In the smart dormitory housekeeping device, the temperature and humidity sensor is a temperature and humidity composite sensor with calibrated digital signal output DHT11 . It applies patented industrial COMS process micromachining technology ( CMOSENS® ), ensuring high reliability and excellent long-term stability of the product. The sensor consists of a capacitive polymer moisture sensing element and a bandgap temperature sensing element combined with a 14 bit A/D Converters and serial interface circuits are seamlessly connected on the same chip. Therefore, this product has the advantages of excellent quality, ultra-fast response, strong anti-interference ability, and high cost performance.

Example 7 :

According to the embodiment 1 or 2 or 3 or 4 or 5 or 6 In the smart dormitory housekeeping device, the sensor used to detect whether there is illegal intrusion is the pyroelectric sensor. There is an initialization time of about one minute after the pyroelectric sensor sensing module is powered on, during which the module will output at intervals 0 ~ 3 times, it will enter standby mode after one minute. The sensing module adopts a dual-element probe, the window of the probe is rectangular, and the dual-element ( A Yuan B Yuan) located at both ends of the longer direction, when the human body walks from left to right or from right to left , There is a difference in the time and distance when the infrared spectrum reaches the dual unit. The greater the difference, the more sensitive the induction. When the human body walks from the front to the probe or from top to bottom or from bottom to top, the dual unit cannot detect the infrared spectrum distance. Therefore, the induction is not sensitive or does not work; therefore, when installing the sensor, the direction of the probe dual unit should be as parallel as possible to the direction of the most human activities, so as to ensure that the human body is successively sensed by the probe dual unit when passing by. In order to increase the sensing angle range, this module uses a circular lens, which also makes the four sides of the probe sense, but the left and right sides still have the characteristics of larger sensing range and stronger sensitivity than the upper and lower directions.
