Here it is illustrated how one can build a soil moisture detector that can be used to monitor whether a plant needs watering or not. The soil moisture detector is build with with just two transistors, a buzzer, a resistor and 3V battery. It is simp…
Here it is illustrated how to build a simple water overflow detector circuit using a single transistor. The transistor is used as a switch which is turned ON when the water level reaches a certain level. A LED is connected to the transistor is then …
In the previous tutorials we explained how an automatic water overflow controller can be build with Arduino and soil moisture sensor YL-69. The first tutorial Water Tank Overflow Detector using Soil Moisture Sensor explained with circuit diagram h…
Here it is shown how the automatic water overflow controller works with simulation in Proteus. This is continuation of the tutorial how to make Water Tank Overflow Detector using Soil Moisture Sensor . In that previous introductory tutorial it is d…
Soil Moisture Sensor sense moisture level of a soil and used for automatic plant watering application which was illustrated in the tutorial Soil Moisture Sensor for Plant with Arduino . But such moisture sensor can also be used for the detection of…
This is a tutorial on plant monitoring system with alarm using Arduino to monitor soils moisture using YL-69(HL-69) for plant watering. Here we will build Arduino plant monitor that monitors soils using moisture(humidity) sensor YL-69(or HL-69 ca…
