Hi i need help for my diy iot farming project. I'm beginner,don't have any coding experience. I cant find any ready to use device to work on my project.
I need to make a weight sensor to trigger my relay to turn on and off my waterpump in certain weight.
Example when the weight is about below 7kg the relay turn on the waterpump and off when the desire weight reach (10kg).
What module/item i need?
How to assemble and pogramm it..
You will need the following
Loadcell
Loadcell amplifier
Arduino.
Interface circuit for your relay.
Power supply for the above.
This is cheap
Without more details helpful practical advice is difficult. But, of course, in addition to those requirements listed by @jim-p, you'll also need some basic study. At least of coding. But are you sure you even need Arduino?
If, for example, the weight on/off target weights were as you said. 7-10kg, perhaps an improvised platform and lever, with a microswitch triggering a relay? (I'm recalling something similar I did to trigger a camera when a fox paid a visit.)
