Arduino Based Compressor Management System

After successfully building a Arduino air pressure regulator in a previous video I decided to build a Arduino based compressor management system.
Now the air pressure thing was fixed there was another small inconvenience that could easily be solved. It happened several times that I forgot to unplug the power cable from my compressor and got woken up in the middle of the night by the loud noise of the compressor filing up. Besides this there is another more serious problem. Compressor compress air. Compressing air generates heat and when the compressor is contained in a box , like I mine is, It causes a possible fire hazard.
The Arduino based compressor management system has to:
- Only switch the compressor on between 9:00 - 17:00
- Only switch on when I’m in my workshop
- And switches off when the compressor is getting to hot
Because a Arduino has no build in clock, I used a RTC for the timing part. For the system to detect my presence in the workshop I decided to use a PIR-sensor module. And the Arduino based compressor management system checks the temperature of the compressor with a temperature sensor
All parts from this project are bought from Banggood.com
Geekcreit® ATmega328P Nano V3 Controller Board: goo.gl/buUMV7
DS18B20 Digital Temperature Sensor Module: goo.gl/Sw5zCz
5V 1 Channel Level Trigger Optocoupler Relay Module: goo.gl/495QqK
DS3231 AT24C32 IIC High Precision Real Time Clock Module: goo.gl/cKBgQk
Mini IR Pyroelectric Infrared PIR Motion Human Body Sensor Module: goo.gl/mtLvZJ
The project turned out to be quid easy and there were no big difficulties. To cool thing about Arduino is that for every compatible part there are numerous great (video)tutorials, so learning to use new parts is super easy. And it’s always good to Know that there is such a big Arduino community that is willing to help you out when you get stuck with a project.

Great job going to use some of this in my diy compressor. Cheers

Nice project. Just one issue I found is that you switched the grounded conductor in the compressor cord (blue wire) when in reality you should always switch the hot conductor (brown). Cheers!

Cool idea! You could use a set of flush cutters on all of those zip ties, the ends that remains are pretty likely to cut/scratch and cause foul language ;-)

CanonGuy Good catch. Too true about tiewraps. I met up with one when it was 35 below. Felt like a scratch. Nothing like a trip to ER with a tiewrap induced gusher on your wrist. You'd think I was wearing a Team Atempted Suicide jersey. My wife had to come and vouch for me.
An easy way to finish tiewraps is to grab the protruding male end with a pair of linesman pliers, or equivalent, flush and tight where it leaves the female latch end, give it a twist or two and it'll shear off clean and smooth.
Take care.

great video thanks! I want to do something similar maybe we can collaborate and sell it ?
I want to control my compressor cut on cut off tank drain valve digital read out with unloader control.
any interest let me know.

Cool project, I'm building myself a fourth air compressor using a water heater tank and a 5hp A/C compressor. I'm using the thermostat from the water heater to prevent overheating situations (strapped to the side of the compressor) and geofencing to detect when I'm home via my phone gps. My arduino is used to measure power usage, and with the help of a flow meter on the output and a linear pressure transducer, to detect for any leaks or anything else that would require an emergency shutdown.
Edit for anyone trying to make a compressor from scrap like this, when reusing pressure vessels, especially if you're welding them like me, you should always test them beforehand. I use a pressure washer and gauge to pressurize the tank to about 100-150psi above the expected pressure of the tank because if the tank fails under water pressure it'll simply start to leak because there's not a lot of stored potential energy. Air compresses and stores a lot of potential kinetic energy so if the failure happens with compresses air you'll have a pretty bad explosion ok your hands which is why I'd rather learn about the failure with the pressure washer and a tank full of water rather than a tank full of air blasting ila home through my garage door as it shoots through like a rocket. Hope that makes sense, it's similar to hydrostatic testing used to certify "professionally" made pressure vessels. Don't attempt if you don't know what you're doing.

Hi, great video 😄.
I'm a beginner and I would like to know if you still have the link to order the compressor?
Thank you in advance 😉.
