Veinasa-THPRW-03 Mini: Weather station for measuring 6 elements: temperature, humidity, pressure, wind speed, wind direction, precipitation, MODBUS

Veinasa-THPRW-03 measures six important weather elements. It stands out for high integration, compact size, low weight, and robust and durable build. With no moving parts, it requires no maintenance or on-site calibration and can simultaneously provide six common environmental weather parameters: wind speed, wind direction, temperature, humidity, atmospheric pressure, and rainfall. It can be used with computers, data loggers, or other acquisition devices that use the same communication format.

Wind speed and wind direction are measured using ultrasound, and the error in the speed of sound caused by temperature variations is avoided thanks to a special calculation method (algorithm). The rain detection uses the radar detection principle and is able to identify the size of falling particles. It can distinguish 8 states: no rain, snow, rain + snow, hail, rain + hail, snow + hail, rain + snow + hail.
