Featuring sealed magnetic reed switches and RJ11 connectivity, it offers reliable, easy-to-interpret data pulses for each weather parameter. The kit includes all necessary mounting hardware for quick installation, making it ideal for agricultural, meteorological, or hobbyist applications requiring accurate environmental monitoring. ## 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. ## Features - Kit represents the three core components of weather measurement: wind speed, wind direction and rainfall. - It uses sealed magnetic reed switches and magnets so you'll need to source a voltage to take any measurements. - All of the sensors in the weather meter kit are passive components.

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 pequeΓ±a 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value for price. Easy to interface. Questionable long term durability. *by on Reviewed in the United States 28 October 2020* 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. ### ⭐⭐⭐⭐⭐ Good kit with one caveat so far *by on Reviewed in the United States 25 August 2023* 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. ### ⭐⭐ Eh.. sad *by on Reviewed in the United States 20 March 2026* This was iffy. Not my proudest buy for a home made weather station. ## Frequently Bought Together - Weather Meter Kit - Station Includes Analog sensors Wind Vane Cup Anemometer Tipping Bucket rain Gauge RJ11 terminated Cables - Bridgold 2pcs MCP3008-I/P MCP3008 MCP 8-Channel 10-Bit A/D Converters with SPI Serial Interface 2.7V,DIP-16. - BOJACK 3 Values 130 Pcs Solderless Breadboard 4 Pcs 830 Tie Points & 400 Tie Points & 126 Pcs Flexible Breadboard Jumper Wires --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/207396010-weather-meter-kit-station-includes-analog-sensors-wind-vane-cup](https://www.desertcart.hk/products/207396010-weather-meter-kit-station-includes-analog-sensors-wind-vane-cup) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-16*
