Arduino Sensor Pod - Mock up

I got all my parts in from eBay finally (well except a 3 volt regulator pack they had to reship). So I soldered up some headers on to a mock up of the layout. I think I may put in the effort and cash to get some custom pcb's for this project. Mainly because this will be a lot of wiring if I don't and a real mess to troubleshoot if there's an issue. I like having the header pins though, makes it easy to swap out parts and move things around.

Wireless Arduino Sensor Unit

Here's the beginning of a project I've been meaning to do a while. Essentially, I'm aiming for this to be a portable sensor unit for arduino. Wireless with an esp8266 and loaded with some sensors that will report their data to a centralized location. Pretty much all the parts will be from eBay and I may even 3D print an enclosure.

So the main things are it needs to be USB powered. The two versions I have planned are via micro USB female and male normal USB, both with a 3.3v regulator so I have access to 5 volts and 3.3 volts without having to use the arduino as a power source (as to not blow out anything).

 


The female micro USB will be so you can plug in a standard phone charger to the unit and the male usb is so you can plug it in to a 120v to 5v USB power brick that many people have.


So as for hardware, I hope to use an arduino mini, esp8266 and a variety of sensors below. Ideally the arduino will host a web server with all of the sensor data in a JSON format. This way it can be queried by something like a program or script and have the data already in a useful format. Perhaps even give it an option to POST directly to elasticsearch.

Feature Wish List:

• Sensors
• PIR sensor
• Ultrasonic range finder
• Laser tripwire
• Temperature
• Humidity
• Light intensity
• Barometric Pressure
• Gas sensor
• LED display - button press shows current IP one digit at a time
• All-in-one package (3D printed enclosure)
• DIP switch to turn sensors on and off
• Master on/off switch
• Laser on/off switch
• Female headers for all sensors (easy to replace)
• Ideally a custom printed PCB with all mounts for best use of space

Perhaps more, perhaps less if I can't find a way to use them all. Or if I can't figure out how to do it.
