AUTOMATIC PLANT WATERING SYSTEMCREATED 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
