| Deze sondes zijn gemaakt door neef Jan. Hij heeft ze 3D-geprint. Zij zijn van RVS en PVC? en bedoeld om de vochtigheid van de grond te meten. Dat kan op vele manieren. Bekijk daarom eerst eens een beetje theorie. |
| Gips in sondes |
|---|
Sommige sensors zijn van gips gemaakt. Hierbij worden de kathode en anode gescheiden door niet nader omschreven gips. Men gaat er van uit dat het gips een evenredige hoeveelheid water opneemt ten aanzien van zijn directe omgeving (de grond). Het voordeel zou moeten zijn dat de in de grondvochtigheid opgeloste zouten een nog kleinere invloed op de meetresultaten zouden hebben.
In use since 1978, the patented WATERMARK sensor is a solid state electrical resistance sensing device that is used to measure soil water tension. As the tension changes with water content the resistance changes as well. That resistance can be measured using the WATERMARK Sensor. The sensor consists of a pair of highly corrosion resistant electrodes that are embedded within a granular matrix. A current is applied to the WATERMARK to obtain a resistance value. The WATERMARK Meter or WATERMARK Monitor correlates the resistance to Centibars (kilopascals) of soil water tension.The WATERMARK is designed to be a permanent sensor, placed in the soil to be monitored and “read” as often as necessary with a portable or stationary device. Internally installed gypsum provides some buffering for the effect of salinity levels normally found in irrigated agricultural crops and landscapes.
De Watermark® grondvochtsensor is een indirecte, geijkte methode voor het meten van bodemvocht. Het is een
elektrische weerstand type sensor. Het grondvocht/temperatuur station converteert de elektrische weerstand van de sensor in een geijkte lezing van centibars van de zuigkracht van bodemwater met een bereik van 0 (natste) tot 200 (droogste) centibars. De Watermark bodemvochtigheidssensor is een product van de Irrometer Company, Inc. |

| Dit project is een doorontwikkeling op een vochtigheidssensor van gardenbot.org voor wat betreft de probes. De software is hetzelfde als de software van de Banggood sensor. Beide sensoren werken dan ook volledig volgens hetzelfde principe: de weerstand van de aarde tussen de 2 probes wordt gemeten. Hierbij wordt aangenomen dat de weerstand lager zal zijn bij een hogere grondvochtigheid. Een Arduino kan geen weerstand meten maar wel spanning. De meting gebeurt dus via een omweg. Het originele programma bevat ook nog andere (overbodige) sensoren, zoals bijvoorbeeld temperatuur en afstand. Daarom hier een gestripte versie van het programma voor het betere begrip. Hieruit blijkt dat er 2 output pinnen (VoltageFlipPin1 & VoltageFlipPin2) en 1 input pin (sensorPin) gebruikt worden om de grondvochtigheid te meten. |
