Sensor development
1, the precision Development: With the automation level of the continuous improvement of the sensor's requirements also must be developed with high sensitivity, high accuracy, fast response, good interchangeability of sensors to ensure the production of new automation reliability. Currently the sensor can produce more than one ten thousandth of very few manufacturers, are far from meeting its production requirements.
2, the high reliability, wide temperature range development: a direct impact on the reliability of the sensor Anti-jamming and other electronic equipment performance, development of high reliability, wide temperature range of the sensor 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, the micro-development: the function of various control equipment increasing, the volume of each part requested location can account for the smaller the better, so the volume is smaller the better sensor itself, which requires the development of new materials and processing technology, the current use of silicon sensors production volume is very small. If the traditional gravity acceleration sensor is made of blocks and springs, larger, poor stability, life expectancy is short, and the use of laser and other micro-processing technology of silicon acceleration sensor made of very small size, interchangeability and reliable are all better.
4, the micro-power consumption and passive development: sensors are generally non-electricity to power the conversion, the work can not do without power grid in the wild on-site or away from the place, often with a battery-powered or solar energy for electricity, development of micro-power sensors and passive sensors is an inevitable direction, 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 1.5μA, while the operating voltage only 2 ~ 5V.
5, to the intelligence of digital development: With the development of modernization, the sensor feature has been broken through the traditional function of the output was no longer a single analog signal (eg, 0 ~ 10mV), but through the micro-computer handle the digital signal after , some even with control, which is what digital sensor.
