Wind Speed Sensor

The wind speed sensor adopts the traditional three wind cup structure, the wind cup is made of ABS material, and has high strength and small starting wind speed. The cup body built-in signal processing unit can output the corresponding wind speed signal according to the user demand. It has variety of output method such as RS485/RS232, pulse, voltage and current, which can be widely used in advertising barrier, meteorology, ocean, environment, airports, ports, laboratories, Industry and agriculture and transportation and other fields.

Calculation Formula

• Pulse mode ( High level: 5V; Low level: 0V):W =0; (F= 0)W =0.1+0.0875×F (F≠ 0)(W: value of wind speed m/s, F: The number of pulses in one second)
• Current type (Range 45m/s):W = (I
• 4)×45/16(W: value of wind speed m/s；I：current type 4-20mA)
• Voltage type (Range 45m/s):W =V/5×45(W: Range m/s；V：voltage signal 0-5V)
