The OWI-432 is more than just a sensor, it serves as both sensor and data acquisition system. Wind, temperature, relative humidity, barometric pressure, hail and ice pellet* may be easily added. This intelligent sensor uses Digital Signal Processing (DSP) for no-drift high-accuracy results. It is the core of our MAWOS system. For MAWOS click here.
