Hi everyone,
I’m currently working on a personal project for my university, and I urgently need your help. I have only 2 weeks left to submit a draft of my project results, and I need to finalize the list of components and get a quotation to request budget approval from my academic advisor.
Project Description:
The goal is to build an automated spraying system using Arduino. Here’s how the system should work:
-
A sensor detects an object passing by (e.g., a fruit or plant).
-
Once detected, the Arduino:
-
First activates a Directional Control Valve (DCV).
-
Then turns on a mini pump to draw water from a tank.
-
Water is then sprayed out through a nozzle.
-
-
When the object is no longer detected, the DCV must immediately shut off.
Parts I need (but I’m not sure which specific models to choose):
-
1x Arduino board (Uno or compatible)
-
1x Object detection sensor (e.g., IR sensor, ultrasonic sensor)
-
1x DCV (Directional Control Valve) – either 12V or 24V, must be Arduino-compatible
-
1x Mini water pump
-
1x Water nozzle
-
Relay module, power supply, wires, or other necessary accessories
My Questions: Can anyone recommend specific models or brands for each of these components that would work reliably together?
I’m under a time crunch, so any quick advice, or recommendations would be greatly appreciated
Thank you in advance!
