![]() Wind direction is calculated (with a resolution of 1.4 degrees) by comparing the relative timing between operation of the two reed switches. The timing of the vane reed switch is determined by the angular position of the vane magnet, which is in turn determined by wind direction. The vane reed switch opens briefly, then closes again as the magnetic shield passes between it and the vane magnet, absorbing the magnetic field.This actuation always occurs at the same angular position of the cups. Given my interest in seeing a high and low temp at my house each day. The anemometer reed switch closes briefly as the anemometer magnet approaches, then reopens when the anemometer magnet has passed. Sper Scientific offers a wide selection of anemometers for directly measuring wind.The anemometer reed switch is normally open, whereas the centered vane reed switch is normally held closed by the strong vane magnet, regardless of wind direction. WS0232 Home Wireless Weather Station Anemometer Digital LCD Outside Wind Speed Direction Chill Temperature Humidity Meter Sensor. Here's how our superbly reliable wind sensor works: A reed switch is a long-lived, hermetically sealed switch that actuates when a magnet is brought near it. Unlike other manufacturers' anemometers, the ULTIMETER does not use a potentiometer for determining wind direction, with its inherent drawbacks of high friction and mechanical wear (using a potentiometer for wind direction is kind of like someone playing with the volume knob on your radio, non-stop). South is indicated when pulses from one switch occur exactly midway between consecutive pulses from the other switch. North is indicated when the two sets of pulses exactly coincide. Wind direction is determined by measuring the relative timing between pulses from the two switches. Wind speed is calculated by measuring the time between consecutive pulses from one switch. Each switch opens and closes once each time the cups go around. The ULTIMETER Anemometer/Wind Vane ("wind sensor") is a patented, uniquely all-digital design containing two magnetic switches. I ts fast sampling rates (up to 100 Hz) make the TriSonica Sphere ideal for UAS-based atmospheric flux and turbulence research, including eddy covariance studies.Can operate over long distances with full accuracy, thanks to all-digital design. ![]() Patent No.: 11,268,974) dramatically reduces the effects of wind shadowing and increases the accuracy of vertical wind measurements. The TriSonica Sphere’s unique patented spherical implementation (U.S. Patent No.: 10,551,406), the TriSonica Mini Wind and Weather Sensor truly gives users the power to “Know the Wind.” With its patented wave signal noise reduction technology (U.S. Its size makes it well suited for portable, temporary deployments, while the fact it has no moving parts, thus eliminating maintenance issues, makes the TriSonica Mini perfect for permanent installations. Small enough to fit in the palm of your hand, the TriSonica Mini is a highly accurate, powerful tool for anyone involved in atmospheric monitoring, weather reporting, and ecosystem research. ![]() Anemoment brings you the world’s smallest and lightest 3-dimensional ultrasonic anemometer, the TriSonica Mini Wind and Weather Sensor, and the TriSonica Sphere Wind Flux Sensor, the industry’s smallest and lightest 3D sensor engineered from inception to deliver more precise vertical wind measurements.
