three-cup wind speed sensor – weather sensor


Product Introduction

The mini three-cup wind speed sensor uses the cup wind as the sensing element, and the magnetic steel is driven by the wind rotation.The reed switch works through the induction of the magnetic steel and outputs the relevant electrical pulse signal. Used in weather stations, environmental protection, transportation and other fields. Factory direct sales, welcome to inquire. The design concept of three cups can effectively obtain the wind speed information, the shell is made of high quality aluminum alloy profiles, the external electroplating spray treatment, with good corrosion, corrosion prevention characteristics, can ensure the long-term use of the transmitter without rust cut phenomenon, and with the internal smooth bearing system, to ensure the accuracy of information collection.

 Three-cup wind speed sensor Features

1.The appearance of the anemometer is a three-cup design, which can reach 359° air volume measurement and strong wind resistance.

2.The shell of the sensor is a polycarbonate shell, which has the advantages of high and low temperature resistance, corrosion resistance and strong weather resistance. It can be used outdoors for a long time.


3.The connecting bearing of the shell of the sensor is an imported part, and the rotation resistance is small, which can ensure the measurement accuracy is higher.

4.Waterproof to wiring design, exterior and interior are waterproof, so that the installation is more convenient, ensure product quality.

5.The product can be used with Jingxun Cloud, and the configuration interface can be configured according to the on-site situation, and the data can be viewed and alarmed at any time.

How wind speed sensors work?

When the wind generated by the airflow drives the sensor to rotate, the central axis drives the internal sensing element to generate a pulse signal. Within the wind speed measurement range, the wind speed has a certain linear relationship with the pulse frequency. The wind speed can be calculated accordingly. The protection level of the wind speed sensor is IP68, even if it is used outdoors for a long time, it can be effectively waterproof and moisture-proof.


Wiring mode of wind sensor with different output modes:

RS485 ouput wind speed sensor wiring

The wiring of the rs485 wind speed sensors have four colors. When using, connect the black wire to the negative of the power supply, the brown wire to the positive of the 10-30VDC power supply, the green wire to the signal wire 485-A, and the blue wire to the signal wire 485-B. That’s it! The wide voltage power input is 10~30V. When wiring the 485 signal line, pay attention to the two wires A\B not to be reversed, and the addresses of multiple devices on the bus cannot be conflicted.

Pulse output wind speed sensor wiring

When using the pulse-type wind speed sensor, connect the black wire to the power supply and signal ground, the brown wire to the 5-30VDC power supply, the green wire to the pulse signal PNPOUT, and the blue wire to NPN (NPNR) OUT. That’s it! Wide voltage power input is 5~30V.

Analog output wind speed sensor

For analog type, we provide three outputs: 0-10V, 0-5V and 4-20ma. When in use, connect the black wire to the power and signal ground, and the brown wire to 10-30VDC (0-10V output wind speed sensors can only use 24V power supply) and measure the analog voltage on the blue wire. That’s it! It can be applied to both four-wire system and three-wire system at the same time.


1.What is the power supply method?

Our existing NB-IOT, lora, and 4G are battery powered, and the others need to be plugged in.

2.What to pay attention to when installing the product?

(1)The mounting bracket is parallel to the groun.

(2)It is flange mounted and fastened to the bracket with screws.

(3)Connect the plug connector with the sensor interface through the reserved route hole.
