<p style="font-style:italic;font-weight:400">Update 13. juli:<br />Det virker. Nu viser regnmåleren nedbør som den skal</p>



<p>En regnfuld sommerdag blev jeg træt af, at regnmåleren ikke altid virker efter hensigten. Det er som om at den ikke altid vipper når der er vand nok i. Ved lidt eftertanke, kunne årsagen være, at det metalstykke, der skal påvirke sensoren sidder for højt, og derfor kan vandet ikke vippe måleren. Jeg har nu flyttet metalstykket ned. Det gør, at der nu kun skal falde ca. 0,3mm regn før den vipper.</p>



<figure class="wp-block-image size-full"><img decoding="async" width="1180" height="726" data-attachment-id="2728" data-permalink="https://tomas.dk/ps/vipperv2/" data-orig-file="https://tomas.dk/ps/wp-content/uploads/2025/06/VipperV2.png" data-orig-size="1180,726" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="VipperV2" data-image-description="" data-image-caption="" data-medium-file="https://tomas.dk/ps/wp-content/uploads/2025/06/VipperV2-300x185.png" data-large-file="https://tomas.dk/ps/wp-content/uploads/2025/06/VipperV2.png" src="https://tomas.dk/ps/wp-content/uploads/2025/06/VipperV2.png" alt="" class="wp-image-2728" srcset="https://tomas.dk/ps/wp-content/uploads/2025/06/VipperV2.png 1180w, https://tomas.dk/ps/wp-content/uploads/2025/06/VipperV2-300x185.png 300w, https://tomas.dk/ps/wp-content/uploads/2025/06/VipperV2-150x92.png 150w, https://tomas.dk/ps/wp-content/uploads/2025/06/VipperV2-768x473.png 768w" sizes="(max-width: 1180px) 100vw, 1180px" /></figure>



<p>Det kræver så også, at der ændres lidt i koden til målercomputeren.</p>



<pre class="wp-block-code"><code>// Variable
float tryk;
float indetemp;
String cmd = "";
volatile int rain = 0;
volatile unsigned long pulseTime = millis();
volatile unsigned long lastPulseTime = pulseTime;
int rain5 = 0;
unsigned long nuTid;
unsigned long tid;
// float VIPFAKTOR = 0.408;  // Vipper V.1
float VIPFAKTOR = 0.294;     // Vipper V.2
int minRain&#91;5] = {0, 0, 0, 0, 0};</code></pre>



<p>VIPFAKTOR er ændret til 0.294 mm pr. vip.</p>



<p>Ny 3D tegning kan hentes <a href="https://tomas.dk/download/VejrStation/Regnmåler_1.1.FCStd">her</a>. Tegning er lavet i FreeCAD 0.21.1.</p>

<p>Det hele samles i en web-server med en mariadb database.<br />Først oprettes en database med:</p>



<pre class="wp-block-code" style="font-size:10px"><code>CREATE DATABASE arduinovejr;
CREATE USER 'vejr'@'localhost' IDENTIFIED BY '_DITPASSWORD_';
GRANT CREATE, ALTER, DROP, INSERT, UPDATE, DELETE, SELECT ON arduinovejr.* TO 'vejr'@'localhost';
FLUSH PRIVILEGES;

USE arduinovejr;
CREATE TABLE vejrdata ( tid DATETIME, temp_inde FLOAT(6,2), temp_ud FLOAT(6,2), tryk FLOAT(6,2), temp_cpu FLOAT(6,2), humid FLOAT(6,2), regn1min FLOAT(6,2), regn5min FLOAT(6,2), temp_1 FLOAT(6,2), temp2 FLOAT(6,2), temp3 FLOAT(6,2) );</code></pre>



<p>Databasen burde nu være klar til brug.</p>



<p>For at hente data til databasen har jeg lavet et lille python script. Python skal være version 3.11 eller derover.</p>



<pre class="wp-block-code" style="font-size:10px"><code>#!/usr/bin/python3.11

import serial
import time
from datetime import datetime
import re
import mysql.connector as mysql

# Setup serial

tty = serial.Serial(port='/dev/ttyUSB0', baudrate=9600, timeout=1)

        database = "arduinovejr")

def speakToArduino(txt):
    tty.write(bytes(txt, 'utf-8'))

</code></pre>



<p>Husk DTR skal være klippet i FTDI kablet, da arduinoen ellers resetter hver gang programmet køres. Brugeren der kører scriptet, skal også være i dialout gruppen. Gøres med: &#8216;sudo usermod -a -G dialout exampleusername&#8217;.</p>



<p>Jeg kører scriptet i crontab:</p>



<pre class="wp-block-code" style="font-size:10px"><code>* * * * * /home/BRUGER/arduinoVejr/getWeather</code></pre>



<p>Dernæst skal der laves et lille php script for at displayenheden kan hente data:</p>

<p>Efter al den snak om at man bør have noget minimumsudstyr til at overleve på, tænkte jeg at det burde være muligt at lave noget selv. I stedet for at købe en radio, der kan trækkes op tænkte jeg at det ville være smartere at bruge noget af det der allerede var i huset.<br />Faktisk viser det sig, at vi har en radio, der kan forsynes med 5V og kan modtage både AM, FM og DAB+. Der ud over har vi en plæneklipper der kører på et stk. 36V batteri. Dem har vi så to af, og de er altid opladte. Derfor er det jo nærliggende at benytte dem som en reserve. Man kan reelt benytte batterier fra boremaskiner og lignende med denne løsning.<br />Jeg købte et USB panel og en buck down på Aliexpress for under 75kr, og spadestik hos T. Hansen. Buck down dimsen omsætter de 36V fra batteriet til 24V, som er det maximale USB panelet kan tage. USB panelet er beregnet til mellem 12-24V.<br />Se løsningen i Galleriet herunder:</p>

<p>Vejrstationen er delt i flere hovedkomponenter:</p>



<ul class="wp-block-list">
<li>Engelsk hus, der indeholder temperatur og luftfugtighedssensor, AM2120</li>



<li>Regnsensor som er af vippetypen. Her kan bruges enten et reed relæ eller en proximity sensor der virker ved 5V.</li>



<li>En Arduino der aflæser værdier fra sensorer og holder dem klar til af læsning fra en webserver. I denne enhed sidder ligeledes lufttrykmåleren.</li>



<li>En stueenhed, der kan vise de vigtigste data. Denne er baseret på ESP32. Den  måler ligeledes stuetemperaturen.</li>
</ul>

<p>Delene der placeres udendørs er printet i PETG og indendørs dele er printet i PLA.</p>



<p>Hvis der er nogen der har interesse, eksporterer jeg gerne til et format der kan læses af andre designværktøjer. Send da en mail til tcj(a)tomas.dk</p>



<p>Opdatering 12. januar 2025:<br />Jeg har opdaget, at der er problemer med vippebunden i det engelske hus. Vippen har det med at hænge p.g.a. at der samler sig en dråbe på undersiden. Overfladespændingen gør, at vippen &#8220;limer&#8221; sig fast. Derfor er designet nu lavet så vandet nemmere render fra og kontaktfladen er minimeret. Der ud over er det en fordel at give både vippebunden og vippen noget silicone. Dette kan enten være på spray eller som siliconefedt. Det sidste holder bedst men det skal være et meget tyndt lag. Det nye design kan hentes via dette link: <strong><a href="https://tomas.dk/download/VejrStation/VippeBundV2.step">VippeBundV2.step</a></strong></p>

<p>Desuden er hængslerne forstærket og der er lavet hul til en 8 mm proximitysensor.</p>
