Sensor development

1. To develop high-precision: 
With the automation level of the continuous improvement of the sensors requirements also must be developed with high sensitivity, high accuracy, fast response, good interchangeability of new sensors to ensure the reliability of automation. Currently the sensor can produce more than one ten thousandth of very few manufacturers, production will fall far short of its requirements. 

2. To the high reliability, wide temperature range of development: 
Directly affects the reliability of the sensor Anti-jamming and other electronic equipment, performance, development of high reliability. Wide temperature range of sensors will be the permanent direction. Improve the temperature range has always been a big issue, most of the sensors in their work in -20 ℃ ~ 70 ℃, the system requirements in the military operating temperature range of -40 ℃ ~ 85 ℃, while the automobile and other occasions, urged the boiler temperature sensors require more high, the development of new materials (eg ceramic) sensors will be promising. 

3. To micro-development: 
The functions of various control equipment increasing, the volume required to account for the various components smaller the better position, which is the smaller size of the sensor itself better, which requires the development of new materials and processing technology, the current use of silicon materials The sensor size is very traditional school, such as gravity acceleration sensor is made of blocks and springs, larger. Poor stability. Life expectancy is short, while the use of laser and other micro-fabrication technology of silicon acceleration sensor made of a very filial volume interchangeability reliability are better. 

4. To the development of micro-power consumption and passive: 

Sensors are generally non-electricity to power the conversion, the work can not do without power grid in the field or away from the scene where, often battery-powered or solar power, development of micro-power sensors and passive sensors direction of development is inevitable, both to save energy and can improve system lifetime. Currently, low-power loss of the chip developed rapidly, such as T12702 operational amplifier, the static power consumption is only 1.5A, while the operating voltage only 2 ~ 5V. 
5. To the intelligent digital development: 
With the development of modernization, the sensor feature has been broken through the traditional function of the output is no longer a single analog signal (eg, 0 ~ 10mV), but through the micro-computer digital signal processing is completed, some even with control This is what digital sensor.
