5 common applications of sensors in life

In order to obtain information from the outside world, people must rely on sensory organs. To meet this situation, sensors are needed. Therefore, it can be said that the sensor is an extension of human features, also known as electrical features. Now introduce you to the five specific applications of sensors in your life:

1. Automatic door: Utilize the body's infrared microwave to open and close the door 2. Smoke alarm: Smoke resistance is used to measure smoke concentration, so as to achieve the purpose of alarm 3. Mobile phone: camera of digital camera, use optical sensor to capture images. Electronic scale: The use of mechanical sensors (conductor strain gauge technology) to measure the pressure of the object corresponding to the variable, so as to achieve the purpose of measuring weight 5, water level alarm: temperature alarm, humidity alarm, optical alarm, etc. are all sensors, is a detection device, It is the first step to achieve automatic detection and automatic control, and brings a huge change to people's lives.
