Hi, yes it is possible, but I don't have free time. I'm busy.

Hi Gianno,BME280 show incorrect humidity value. So I change DS18B20 to DHT22. But after two or three weeks it show incorrect value too. So I don't know best sensor to measure humidity outside.Check your DS18B20 sensor wires. Maybe wires get corrosion and connection goes bad. BME280 can be used to measure temperature. Yes it is possible read BME280 and the DS18B20 sensor (or the DHT22) and average value.

I don't know. You have to check it rotating wind vane by hand. If it show correct wind direction it is al right, else it is not.

Hi,I think your wind vane is rotating and don't hold position. You will need bigger rudder. Or you need increase friction to slow down rotation. I have another weather station similar like yours and wind direction show correctly. Maybe Wunderground it takes 5 minutes to average wind direction. So it show 16 direction. It is mine thoughts.

Hi, just download code again. Code was updated.

Hi Kevin, I just replace DS18b20 temperature sensor with DHT22. DHT22 for temperature and humidity, BME280 only for pressure. But I didn't update Instructables sketch.

Hi KVnVA,Thank you for your information.

Hi andreas.de.keersgieter,I think you will didn't find similar project as you want. So it will be more simple to modife mine code.

Hi, Wunderground imperial system, Weathercloud - metric SI system. 1 mph is 0.447 m/s

Hi JonathanP51, I think your BME280 sensor is bad. Your BME280 sensor with 4 or 6 pins ?

Hi Knoxen,// 2.4km/h convert to miles is 1.4912 mph. 1.49 / 30 seconds = 0.0497. windSpeed = Rotations * 0.0497;

Hi, I don't know how to do that.

Remove this line >> ESP.restart(); What it is your main board ? Nodemcu ESP12 or Wemos ?

Correct this line

client.print("/ HTTP/1.1\r\nHost: rtupdate.wunderground.com:80\r\nConnection: close\r\n\r\n");

//Correct this line client.print("/ HTTP/1.1\r\nHost: rtupdate.wunderground.com:80\r\nConnection: close\r\n\r\n");

Hi Kevin, we need just wait.

Hi ;)I just get message that ,,Weather Underground Sensor Signup will be temporarily unavailable for maintenance between Monday Jan. 27th and Wed. Jan. 29th." So we need to wait.

Oops, I don't modified one thing. Serial.print("DS18B20 = "); Serial.print(tempc_min); Serial.println(" C ");change to this >>> Serial.print("SHT10 = "); Serial.print(tempc_min); Serial.println(" C ");

Hi Kevin, I just now create another mathwork account. So I dindt know why you have problem.

Very similar like Tula TMZ 5.951 motorcycle https://www.youtube.com/watch?v=QTjaqRq_q6M

Hello, I don't know what you mean. rst - reset ? ESP.restart(); ?

Hi, It is simple voltage divider.

Board manager ESP8266 - 2.5.0

Hi Nico, thanks for indormation.

https://apicommunity.wunderground.com/weatherapi/topics/end-of-service-for-the-weather-underground-api

Hi Giuseppe,Wunderground change api. So old api code didn't work with new api.

Yes I was create 2 weather station with oled and with tft 2.8 display. But Wunderground api end of service. https://apicommunity.wunderground.com/weatherapi/t... So now I get weather data from DarkSky and OpenWeatherMap. Now it is easier to send data to Thingspeak. And from Thingspeak get weather data and display to Oled or tft screen. But I didnt have time at this moment.

1. Mine weather station working 2 years, but I didn't get abnormal pressure readings. But I create another weather station for mine friend and he have problem with abnormal pressure, and humidity. So I think BME280 sensor is bad.2. BME280 sensor buy from Ebay ( China seller) 3. I just add compatibility to send sensors data to Thingspeak.com. Fix average wind direction for Weathercloud. And just add WiFi signal strength ( RSSI)

..

I print players with ABS plastic. But they always broke. So after one year I bought new from eBay https://www.ebay.com/itm/26-Foosball-table-Men-Player-Soccer-Table-FOOTBALL-NEW-Black-White/281082481466?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

If your main board is ESP32, why you need Arduino? Arduino only for rain counter? If EP32 can connect to ntp time server, why you need DS3231 RTC ?

Grazie Giuseppe

I didn't change wind direction settings.

Can you explain about pressure correction. How to correct?

I just edit and upload your code. I didn't edit your wind direction. Upload your last code to check wind direction it is working or check vane-value again.

Ciao Giuseppe,I change delay from 50ms to 2000s to read DS18B20 sensor. And now temperature will be not minimum value , but higher value. So if delay did not solve this problem, so negative temperature value will be eliminated. So always show maximum temperature value.

1. What temperature sensor are you using? DS18B20 or BME280. I know your problem. Send me your code and I will fix.2. 1.492mph / 30 seconds = 0.05 285 line windSpeed = Rotations * 0.05; 3. bool debug = 1; 153 line change it to ,,1''

Next time if you need help for soldering small smd parts write to me. I will try to help you.

1) Yes it is correct. 2) You don't need to modify this. This function for average analog value.

// Upload this code to know vane-valueint analogPin = A0;int vane_value = 0; void setup() { Serial.begin(115200); // setup serial}void loop() { vane_value = analogRead(analogPin); // read the input pin Serial.println(vane_value); // debug value delay (3000);}

// Upload this code to know vane-valueint analogPin = A0;int vane_value = 0; void setup() { Serial.begin(115200); // setup serial}void loop() { vane_value = analogRead(analogPin); // read the input pin Serial.println(vane_value); // debug value delay (3000);}

fix code

It need less energy, rain reset more accurate.

see doc file

I mean change this value. Try lower to 0.12, 0.10, 0.7, 0.5

Reduce this value (red rectangle)

I didn't understand why you need to change it

In ESP12-F example GPIO15 pin (D8) by 1K ohm resistor connected to ground. Maybe it is not necessary but I connected it.

Hi Giuseppe,I add photos, so correct code. Wind direction vane value you had adjust by yourself. These value it is for example.

Hi Giuseppe,1) 10C it is the RealFeel Temperature is an index that describes what the temperature really feels like. It is a unique composite of the effects of temperature, wind, humidity, sunshine intensity, cloudiness, precipitation and elevation on the human body--everything that affects how warm or cold a person feels.2) BME280 temperature was fix. Try now. I just accidentally remove request command from BME280 sensor. 3) Sending data to Wunderground.com I'm using 30 seconds loop. 10 minutes loop sending data to Wundercloud.net

Hello,Davis anenometer and Ventus rain gauge it is for example. You can use another models. I'm also beginner in programing. So I will try to help you.

Hello Manfred,So ESP8266 WiFi module connect to ntp time server and get time. For example if time reach 23:55 wifi module reset rain. I get information, from this web site "ChyneHome" chynehome.com/web/wp-content/uploads/2015/10/Personal_Weather_Sation_ESP8266_V2.ziphttp://chynehome.com/web/

upload this code and check your button analog value https://www.arduino.cc/reference/en/language/functions/analog-io/analogread/and adjust this value >> int Button[8][3] = {{1, 905, 919}, // button 1 0R -- Black UP

Hello, check your Arduino libraries folder. Maybe do you have another IR remote library which conflict with ,,Arduino-IRremote-master" library

There are two ways to program ESP8266 . Usb dongle connect to ESP8266 and send AT commands via serial monitor or Arduino Uno connect to ESP8266. and send AT commands via serial monitor. Usb dongle is compatible.

Dip switch used for enable or disable ESP-12 wifi modulle. If you want to use ESP-01, turn off dip switch.

If you didn't have usb serial ttl adapter, you can use Arduino as programmer. You have to use this code. #include <SoftwareSerial.h> SoftwareSerial esp8266(10,11); // make RX Arduino line is pin 10, make TX Arduino line is pin 11. // This means that you need to connect the TX line from the esp to the Arduino's pin 10 // and the RX line from the esp to the Arduino's pin 11void setup(){ Serial.begin(115200); esp8266.begin(115200); // your esp's baud rate might be different} void loop(){ if(esp8266.available()) // check if the esp is sending a message { while(esp8266.available()) { // The esp has data so display its output to the serial window char c = esp8266.read(); // read the next character.

Yes you can use Wemos. At this moment I am creating another weather station based on ESP8266 as main board. So wait if you can.

Hi, you only need one WiFi module. You can use ESP8266 ESP01 or ESP12.

Hi, #define DEBUG 0#define DEBUG 1 // I was using only if I want to check sensors data on serial monitor. Do you change weather station ID and password ? char ID [] = "XXXXXX"; //wunderground weather station ID String PASSWORD = "xxxxxx"; // wunderground weather station password

Hello Gregory, Do you have connected your ESP8266 to your router? Code it used a lot of memory. Try disable ,, serial monitor" Debug 0.

Radio signal strength is good? If radio signal strength is not good RDS will not display.

#define DEBUG 0 //change to DEBUG1 it will show in serial monitor more information. Press ,,R" and you will get more RDS information from radio station. check void displayRDS (void) PS, PTY, EON, TP, TA

Hello, so you need solar charge controller, battery 12V or 6V , and solar panel. For example if you have LiPo 2200mAh battery with a load that draws 100mA. 2.2/ 0.1 = it takes 22 hours. So if you have one cloudy day your weather station discharge your battery. You will need add another battery or battery with larger capacity.

Sveikas Dainiux22Šiuo metu neturiu laiko į visą tai gilintis, bet galiu duoti nuorodą kaip pavyzdį nuo ko pradėti.. Pagrindinė plokštė ESP8266 tai ir programa skiriasi. https://webcache.googleusercontent.com/search?q=ca...

Tools > Board:Arduino Uno ? I think you select ESP8266

If I am right it use about 3kB

I was used clear plastic with silicone to encapsulate UV sensor. I can't compare UV sensor value with another UV sensor. So I can't confirm that UV sensors show data is correct.

I was have problem with server "weatherstation.wunderground.com". So now I was using rtupdate.wunderground.com. So just ignore it ("weatherstation.wunderground.com"). ''Debug 1" I am using only to check sensors. So if you want sent data to WU disable Debug 0. Main program using a lot of memory. Disable it and it will use less memory and main program will be more stable.
