Introduction
Ever want to build your own weather station? DFRobot brings you this new version of the weather station kit that integrates anemometer, wind vane and rain gauge. All data can be read directly through the serial port. Also, it is compatible with Arduino devices, which is convenient for users to use. The weather station kit can effectively detect regional weather parameters like, wind speed, wind direction, and rainfall, or be used in agriculture, industry, and climate research fields in combination with DFRobot's other sensors.
Note:
- Update on 2016/3/28: upgrade the temperature and humidity sensor, improve the measuring range
- Update on 2020/6/18: modify the wind speed parameter description
Specification
- Operating Voltage: 3.3V
- Temperature Range:-40 - 125℃
- Humidity Range: 0~100%
- Dimension: 24 X 69 X 100mm / 0.952.723.94 inches
Application
- Weather station
- Weather monitoring
Board Overview

No. | Description |
---|---|
B | Rainfall |
C | Wind speed and direction |
D | Data output |
E | Indicator light |
I | I2C temperature, humidity and air pressure port |
J1 | Metric & Imperialb Jumpers |
J2 | Data interface 2400/9600 baud rate Jumpers |
Our code uses 9600 as the default serial port baud rate. If you upload our sample code directly, you will need to unplug the J2 jumper cap and install the J1 jumper cap.
Data Output Format
c000s000g000t082r000p000h48b10022*3C
Output 37 bytes per second, including CR/LF at the end of the data.
Data Analysis:
- c000: Wind direction angle, unit: degree.
- s000: wind speed in 1 minute, unit: miles per hour
- g000: the highest wind speed in 5 minutes, unit: miles per hour
- t086: Temperature (Fahrenheit)
- r000: Rainfall in 1 hour (0.01 inches)
- p000: Rainfall in 24 hours (0.01 inches)
- h53: Humidity (00% = 99%)
- b10020: Air pressure (0.1 hpa)
Note: The board will make a hardware self-check before it works, it will output “...” when it doesn’t detect the related devices. For example, If the temperature & humidity sensor and barometer are not installed or broken, it will output: '''c000s000g000t...r000p000h..b..... '''
Indicator Light
- DAT flashes synchronously when sending data
- TX flashes synchronously when sampling wind speed
- RX flashes synchronously when rain sensor is working

Connection Diagram

Please unplug the cable on the TX&RX interface, or it will interfere with the sketch uploading.
Sample Code
Expected Results
Note: Due to the fact that there is no wind in the test environment, all parameters related to wind speed and wind direction are 0.

FAQ
Q1. About the module assembly: I only found there are only two installation blocks for the different modules on the Converter Board, but there are three modules: Anemometer, Wind vane and Rain bucket to be installed on the Converter Board. How come?
A: There are two ports under the anemometer, you need to connect the anemometer to the wind direction and then connect to the adapter board, as shown in the figure:
