Project description/Specifications
We wanted to create a system using Arduino to measure the moisture levels of multiple plants and to
effeciently
deliver water to them.Slide3
Required parts and cost
Soil Moisture Sensor x4
Mini Water Pump X4
L298 Dual H-Bridge Motor Driver x2AC/DC Power Adapter4mm Pipe for Pump x4
Sensor Shield
Total Cost: $54.60Slide4
Moisture sensor
Uses two probes to pass current through the soil and then reads the resistance to get the moisture level.
Power: 3.3 V or 5 V
Output voltage signal: 0-4.2 V
Current: 35 mASlide5
Arduino and shieldSlide6
AC/DC Adapter
Supplies additional current to the driver for the pumps.Slide7
Pump Drivers
Provides up to 2 A each for the two connected pumps
Controlled by switching high and low states on a pin on the ArduinoSlide8
Pumps
Draw 1.76 A and between 3 to 9 VSlide9
