Human civilization has developed to today, and it is the human curiosity and imagination that pushed the society forward. What makes modern society more perfect is that people have new demands for the life quality.
Once we used geodetic instruments to know the earthquake. Later, we had a seismic monitoring system. Once we used the naked eye to observe the stars and predict the sky, then the Hubble telescope observed the particles emitted by the galaxies 1.34 billion light years away. Once we only knew hot and cold, do not know the specific temperature, then we have a thermometer, we have mercury thermometer, infrared thermometer, passive wireless thermometer.
Today, the trillions of IOTs are closely related to us, and the traditional methods of perceptual measurement are no longer enough to meet the needs of constantly changing and changing. People are limited to wired data transmission, and wireless data transmission has a variety of ways, people can choose the way that suits their needs.
When we focus on energy harvesting and passive wireless applications, we find that temperature is just the beginning. There are more needs and more application areas are waiting for us to develop. Passive wireless acquisition of humidity, pressure, vibration, and light sensitivity provides us with a wider range of applications.
The SENHUB-LAU1 chip has a built-in temperature sensor, a 14-bit analog-to-digital converter (ADC) and a signal conditioning circuit. The built-in analog interface allows external connection for the sensor front ends of resistive, capacitive, voltage, current, and bridge type. Passive wireless acquisition of data (temperature, humidity, pressure, vibration, light, etc.). When the chip built-in sensor works, the sensitivity of the chip is -18.7dBm; when the external sensor front end meets the requirements, the overall sensitivity is between -14dBm and -17dBm. With the mainstream RFID reading and writing equipment, the model can be built in about 10 meters. Passive wireless sensing application system.
LAU1 combined with various sensors can be used for equipment temperature and humidity monitoring, new energy car wash battery monitoring, tobacco storage monitoring, tire pressure monitoring, valve loose monitoring, vehicle collision monitoring, landslide monitoring, building safety monitoring, road bridge stress monitoring, visualization RFID (control lighting LED lights) and other applications.
Xiamen Innov Information Science & Technology Co.,Ltd. cooperated with VBL and nossamae to develop and produce the temperature sensor tags. The tags can be designed to measure and endure a wide variety of conditions while wirelessly transmitting its sensory information in real-time. Widely used in cold chain for logistics, containers, warehouse,etc. To avoid unnecessary loss caused by the incorrectly temperature control.
