Soil Moisture Detection Module for Arduino
Calibrate Moisture Level for Detect
This listing is a little difficult to explain, so please make sure to watch the video after reading this. This listing is for a soil moisture detector module and sensor board. The sensor board has two sharp prongs that can be set into your plant soil. You can calibrate the device to output a digital signal when there is too much moisture. You can calibrate the output to detect between zero to roughly 300 ohms. The more moisture in the soil, the less resistance. This may take some tweaking and experimenting at your end, but you can easily interface this bad boy with your arduino. There are four interface pins on the main board, the you're only going to need three to interface with your arduino or other micro controller. The first is "VCC", which is where you connect your power supply of 5v (No more than 5v). The second is "GND", which is your supply DC ground pin. The third is "D0", which is your digital output (0-5v). the last one is A0, but you don't need to worry about that pin. In the video, I simulate moist soil with a 100 ohm resistor, and a dead short. Please watch the above video, and if you have any questions at all, please do not hesitate to ask!
