Weather Meters

Whether you're an agriculturalist, a professional meteorologist or a weather hobbyist, building your own weather station can be a really rewarding project. When you're measuring weather, however, you need some pretty specialized sensors. This kit represents the three core components of weather measurement: wind speed, wind direction and rainfall.

None of the sensors in this kit contain active electronics, instead they use sealed magnetic reed switches and magnets so you'll need to source a voltage to take any measurements. The positive side of this is that the sensors are easy to interpret:

The rain gauge is a self-emptying bucket-type rain gauge which activates a momentary button closure for each 0.011" of rain that are collected. The anemometer (wind speed meter) encodes the wind speed by simply closing a switch which each rotation. A wind speed of 1.492 MPH produces a switch closure once per second. Finally, the wind vane reports wind direction as a voltage which is produced by the combination of resistors inside the sensor. When a voltage is supplied, the voltage returned can be translated to any of 16 possible positions. For more information on how this works, as well as a table of voltage and resistance values for each position, refer to the manual below.

All of the included sensors are supplied with RJ11 terminated cables, for information on the pin-out of the cable, check out the datasheet.

Dimensions: 28.5" x 8"

Kit Includes:
  • Wind Vane
  • Cup Anemometer
  • Tipping Bucket Rain Gauge
  • Two-Part Mounting Mast
  • Rain Gauge Mounting Arm
  • Wind Meter Mounting Bar
  • 2 x Mounting Clamps
  • 4 x Zip Ties

Note: Some basic assembly is required.

GDS-3000 Series digital storage oscilloscopes

GW Instek GDS-3000 Series digital storage oscilloscopes are equipped with a built-in self-developed waveform image processing system which significantly enhances the waveform capture rate. We call this VPO (Visual Persistence Oscilloscope) Technology.

The first generation of analog oscilloscopes (Analog oscilloscope CRT display as shown in Figure Fig. 1a) utilized fluorescent materials to capture fast electronic signals to generate a dot on a screen. By controlling the intensity and bias of an electron beam, the brightness and tracking of a signal could be generated. This was used to reconstruct a waveform image that would be displayed on a screen for a short time. For this reason, one can observe the details of a signal while the signal is changing with the naked eye.


Digital storage oscilloscopes, usually viewed as 2nd generation oscilloscope (DSO, as shown in Figure Fig. 1b) mainly convert analog signals into digital signals through high-speed analog to digital converters (ADC). These signals are then stored in its memory for the CPU to process and draw the waveform. The design of a DSO puts some of its functions far beyond the reach of analog oscilloscopes. For example: waveform storage, math operations (Example: - * / FFT), automatic measurements and pre-triggers. The only reason why analog oscilloscopes still fascinate so many people is because of their ability to display a signal in real-time. 

Conversely, this is also the greatest disadvantage of digital storage oscilloscopes. As the CPU in a DSO does not have the processing power to process a waveform as fast as the signal is changing, only part of the signal is captured and processed. The section of time for when a signal is not captured is called Dead Time (Fig. 1c). The longer the dead time is, the greater the chance of not detecting a rapid change in the signal. If a DSO cannot detect such signals then it is unable to meet the demands of a modern measurement instrument.


The waveform image processing system designed and developed by GW Instek are mainly used to share the data processing with the CPU, shortening the time needed to draw a waveform and consequently increasing the waveform capture rate.

Furthermore, in order to create a display performance similar to that of analog oscilloscopes, the waveform data for all channels is displayed as a three dimensional image (amplitude, time and intensity). When a strong signal is generated, the waveform will be brighter and the waveform will persist for a longer time, allowing users to easily grasp any instantaneous changes in the waveform. By using an image processing system, waveform data can be quickly acquired by the DSO, processed and displayed on the screen with multiple levels of intensity almost as quickly as an analog oscilloscope.

It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. The DFRobot ATMega1280 MEGA USB Microcontroller can be powered via the USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. This board is almost identical to the Arduino MEGA with the exception of the color of the PCB.
