PROJECT TITLE :
Design of a CMOS Digitized Wind Transducer With Noise Insensitivity for Wind Environmental Monitoring Applications
In this paper, a CMOS digitized wind transducer with noise insensitivity for wind environmental applications is newly proposed. The proposed chip is attractive thanks to the fact that it can monitor the present wind conditions and then quickly response to controllers or computers by combing numerous wind sensors with the proposed digitized wind transducer together. The output signal of the proposed chip may be a pulse stream, it may be easily sent over a big selection of transmission media, like package switch network, radio, optical, infrared, ultrasonic, and so on. Totally different to previous works, the proposed chip is appropriate for processing at a varied vary of wind speed and additionally insensitivity to wind noise for wind environmental monitoring applications. All the functions and performance of the proposed digitized wind transducer are successfully tested and proven through measurements and confirmed it to be applied on the flowers in greenhouse applications. The measured range of wind speed is from 2.two to 8 m/s, and its corresponding measured signal-to-noise-distortion ratio is obtained from 53.6 to 74.half dozen dB. The chip space is 1.two × 2.two mm2 . The proposed chip is appropriate for wind environmental monitoring devices, like wireless sensor network devices.
