Wind Speed Sensor

Product Manual

Three-cup wind speed sensor is a wind speed measuring instrument independently developed and produced by our company. The sensor shell is made of Polycarbonate material, with very small dimensional tolerance, and has high weather resistance, high strength, corrosion resistance and water resistance. Internal integration of photoelectric conversion mechanism, industrial microcomputer processor, standard current generator, current driver, etc.

The circuit PCB adopts military-grade A-grade materials to ensure the stability of measurement parameters and electrical performance; the electronic components are all imported industrial-grade chips, which makes the whole have extremely reliable anti-electromagnetic interference ability, and can ensure that the host is at -30 °C-75 °C, It can work normally within the humidity range of 5% to 95%RH (non-condensing) .

After the product is upgraded, the output signals are various. The wired output includes: analog signal (voltage, current) , digital signal RS485; the wireless output includes: LoRa, Bluetooth, WIFI, GPRS, 4G, NB-lOT, CAT-1, wireless output except LoRa and Bluetooth, the other four forms can be connected to the smart cloud platform, which can realize the monitoring and management of smart terminal data.

(1) The sensor has a compact design and high measurement accuracy.

(2) Fast response and good interchangeability.

(3) Really realize low cost, low price and high performance.

(4) The flange installation method can realize the bottom line and the side line, which is simple and convenient.

(5) High data transmission efficiency and reliable performance to ensure normal operation.

(6) The power supply has a wide adaptable range, good linearity of data information, and long signal transmission distance.

(7) It has two parameters, wind speed and wind level, with reliable data.

This product is widely used in wind speed measurement in greenhouses, environmental protection, weather stations, construction machinery, ships, docks, breeding and other environments.

4.2 Impedance Requirement of Current Signal

Wind Speed Sensor can be connected to various data collectors with differential inputs, data acquisition cards, remote data acquisition modules and other equipment. The wiring instructions are as follows: 

Mounting arm accessory:

Cross arm can be install CC-G08,CC-E01,wind speed and direction sensor.

Small plate for install wind speed and direction sensor:

V: Voltage value collected by the collector; unit: V;

A: The current value collected by the collector; unit: mA;

P: The number of pulses collected by the collector within 1s, unit: piece;

RS485 Signal(Default address 01) 

Standard Modbus-RTU protocol, Baud Rate: 9600; Check Bits: no; Data Bits: 8; Stop Bits: 1

7.1 Modification Address

For example: Change the sensor with address 1 to address 2,host→slave

If the sensor receives the correct data, the data will be returned in the same way.

Note: If you forget the original address of the sensor, you can use the broadcast address 0XFE instead. When using 0XFE, the host can only connect to one slave, and the return address is still the original address, which can be used as an address query method.

7.2 Query Data

Query the data (wind speed, wind level)  of the sensor (address 1) , host→slave.

If the sensor is received correctly, it will return the following data, slave→host.

(1) Please check whether the packaging is intact, and check whether the sensor model and specifications are consistent with the product you have purchased.

(2) Do not wire with power, and then power on after the wire is connected and checked.

(3) The user should not change the soldered components and wires of this product after it leaves the factory.

(4) The sensor is a precision device, please do not disassemble it by yourself when using it to avoid damage to the product.

(5) Avoid sticky particles from entering the sensor, prevent moisture, so as not to affect the measurement performance.
