A passive infrared sensor uses two detectors having elements of different configurations such that each element outputs a respective frequency when an object moves in front of it. Based on the presence of two frequencies with similar peak and/or slope characteristics, a motion signal is output to...
'PIR Motion Sensor' 'Infrared Sensor'(较通用,可能不特指被动式) 说明/解释:这些同义表达都用于描述通过检测红外辐射来感知物体(如人体)移动的设备。 对于“个人信息检索”: 'Personalized Information Retrieval' 'Individual Information Retrieval' 'User-specific Information Retrieval'...
MQ Series Gas Sensor The description of each MQ series gas sensor and its uses that follows will be helpful to anybody who wants to understand the foundations of gas sensing technology. The MQ Series Gas Sensor is a revolutionary technology designed for the detection of combustible gases, such ...
Sensor uses 1.6mA@3.3V. The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows multiple motion sensors to be connected on a single input pin. If any of the motion sensors go off, the input pin will be pulled low. ...
and wireless communication that stores the data received by the sensors into the cloud. This is very useful to obtain data and conclude the values in a graph. There was no backup of values because the coverage of internet using GSM was not efficient. The smart home system [1] uses IOTSHS...
