Schmeatic of an wireless sensor node capable of acquiring wind data within a mean fitting deviation of ±0.063398 m/s, store them and present them wirelessly to an IEEE 802.15.4 protocol sink node

Sallen-Key low pass filters are second-order active low pass filter. The design of Sallen-Key filters is similar to voltage-controlled voltage-source (VCVS), with filter characteristics such as high input impedance, good stability, and low output impedance.
