AUTOMATIC PLANT
WATERING SYSTEM
CREATED BY: KOOSHA DANESHI, CHAO JIANG, ALASTAIR FRASER
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.
REQUIRED PARTS AND COST
• Soil Moisture Sensor x4
• Mini Water Pump X4
• L298 Dual H-Bridge Motor Driver x2
• AC/DC Power Adapter
• 4mm Pipe for Pump x4
• Sensor Shield
• Total Cost: $54.60
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 mA
ARDUINO AND SHIELD
AC/DC ADAPTER
• Supplies additional current to the driver for the
pumps.
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 Arduino
PUMPS
• Draw 1.76 A and between 3 to 9 V
