## Overview

The Weather Meter Kit by SparkFun combines analog wind speed, wind direction, and rainfall sensors using magnetic reed switch technology. Designed for easy integration with external voltage sources and microcontrollers, it includes all mounting hardware and RJ11 cables for straightforward assembly. Ideal for agricultural, educational, or hobbyist weather monitoring projects, this kit delivers precise, real-time environmental data with a durable, weather-resistant design.

## Description

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. The vane’s magnet may close two switches at once, allowing up to 16 different positions to be indicated.All of the included sensors are supplied with RJ11 terminated cables, for information on the pin-out of the cable, check out the images.

Review: Good value for price. Easy to interface. Questionable long term durability. - I interfaced these wind and rain sensors to an Arduino. The sensors are actually just simple magnetic switches. The anemometer has a magnetic reed switch that closes every time it rotates around one time, and it has "somewhat" of a linear ratio of wind speed, to # of rotations per second. The wind vane uses multiple magnetic reed switches to create a resistor based voltage divider to generate different voltages for the 8 wind directions. Most of the time, you will only get directions for N, NE, E, SE, S, SW, W, and NE, but sometimes you can get 2 switches to close and get the inbetween directions of ESE, WSW, ENE, etc... not every unit seems to do this, and you cannot reliably get all 16 directions, so when programming, assume you're only going to get the 8 cardinal directions. The rain gauge is also another simple switch. Every time the measuring bucket inside the gauge tips, the switch will close/open. Every tip / switch change equals .011" of rain. Just count the number of switch toggles and you get rain fall. You can measure the time between tips to get the rate of rainfall in inches/hour. The 3 sensors are all made of plastic as are the supporting arms. The metal pole and screws used to attach the sensors seem like stainless steel. The sensors use RJ11 (telephone jack) connectors to connect. The wire from the sensors doesn't seem like anything weather resistant, so I an concerned that long term UV exposure will damage them in the long term, but right now I am just speculating. I got all of mine hooked up to an Arduino Nano and they work well for now.
Review: Good kit with one caveat so far - So far the kit has been good, from what I can tell somewhat accurate result though I'm still in the building phase of my weather station. I do have one caveat though. If you are using this kit with SparkFun's weather shield, you will need to edit their source file of the "Weather Meter Kit" library. Specifically the SparkFun_Weather_Meter_Kit_Arduino_Library.cpp file. There is a comment about the shield using a different circuit therefore the values are different. I was getting wildly inaccurate wind direction readings and thought it was defective. Going to their sight and finding the weather meter station data sheet, I was able to confirm all of the readings of the resistance by direction were accurate. That meant the problem was either code or on the shield. Turns out a bit of both. In the referenced file I commented out these lines: // _calibrationParams.vaneADCValues[WMK_ANGLE_0_0] = 3143; // _calibrationParams.vaneADCValues[WMK_ANGLE_22_5] = 1624; // _calibrationParams.vaneADCValues[WMK_ANGLE_45_0] = 1845; // _calibrationParams.vaneADCValues[WMK_ANGLE_67_5] = 335; // _calibrationParams.vaneADCValues[WMK_ANGLE_90_0] = 372; // _calibrationParams.vaneADCValues[WMK_ANGLE_112_5] = 264; // _calibrationParams.vaneADCValues[WMK_ANGLE_135_0] = 738; // _calibrationParams.vaneADCValues[WMK_ANGLE_157_5] = 506; // _calibrationParams.vaneADCValues[WMK_ANGLE_180_0] = 1149; // _calibrationParams.vaneADCValues[WMK_ANGLE_202_5] = 979; // _calibrationParams.vaneADCValues[WMK_ANGLE_225_0] = 2520; // _calibrationParams.vaneADCValues[WMK_ANGLE_247_5] = 2397; // _calibrationParams.vaneADCValues[WMK_ANGLE_270_0] = 3780; // _calibrationParams.vaneADCValues[WMK_ANGLE_292_5] = 3309; // _calibrationParams.vaneADCValues[WMK_ANGLE_315_0] = 3548; // _calibrationParams.vaneADCValues[WMK_ANGLE_337_5] = 2810; and uncommented the similar lines immediately below them. Now the wind direction is accurate.

## Questions & Answers

**Q: Is it durable in the long term? I mean, is it industrial quality or it is intended to be used only by hobbyists?**
A: I’ve had mine installed in the weather for 15 months with no visible weathering. It’s not industrial quality, but sufficiently sturdy to survive the Florida weather.

**Q: Quiero comprar  pequeña estacion metereologica, cuanto me cuesta y tiempo de entrega a bolivia**
A: The Amazon system should be able to give you delivery time and cost.

**Q: No outdoor temperature?**
A: Temperature is usually done digitally and is often times included in whatever weather board you chose to hook up to this kit to read the analog sensors.  These are just the analog sensors that you might want to use along with a weather board and other digital sensors you might want to include.

**Q: Can you recommend me a board to use this product on a Raspberry Pi?  thanks.**
A: We do not make a pi hat or companion board that is designed to go with Raspberry Pi boards.  It may be that you will need to use a combination of boards/sensors to make it work if you have a specific Raspberry Pi board in mind.  However, we do have a Raspberry Pi RP2040 processor board for MicroMod and a MicroMod Weather Carrier board that will work.

### ⭐⭐⭐⭐⭐ Good replacement for Ambient Weather parts
*by J***. on May 9, 2023*

I had an Ambient Weather model 2080 whose anemometer had quit registering on the base station, so I ordered SparkFun's weather meter kit. It was a perfect match for the Ambient Weather pieces. All I had to do was plug it into the power source/transmitter in the thermometer/humidity part for it to work. Here's a workaround for the only drawback I found, which was that with an additional length of pipe to work with, there was no way to keep the top pipe from twisting on the bottom pipe, which changed the reported wind direction. The SparkFun kit came with no instructions, so here's what to do: the arm which holds the rain gauge piece has a collar to hold it on the pipe, with two screws on top and two on the bottom. Secure the top two screws on the top pipe and the bottom two screws on the bottom pipe, with the seam between the pipes in between. This will prevent the top pipe from twisting and changing the reported wind direction.
