The Dyacon Wind Anemometer Sensor is a durable device designed to measure wind speed and direction. It utilizes three rotating cups or cones driven by the wind, with rotational speed corresponding to wind velocity. The wind direction is determined using a lightweight vane with an arm that aligns with the wind’s angle; the vane’s position indicates the wind direction. This Modbus-enabled smart ...

A soil infiltrometer is a device used to measure the rate at which water infiltrates into the soil. That is, how quickly water moves from the surface in the field into the ground. Infiltration rate equals the change in water depth on surface divided by time. Time intervals measurements are typically every 5 to 10 minutes. It is widely used in agriculture, hydrology, environmental science, ...
