Outdoor sensor MarkII

The outdoor dust sensor markII is a simplified version of my Dust and particles monitoring with Sharp GP2Y1010AU0F

Instead of powering the sensor from solar panel i'm going to power it from 220AC by using a scraped 12VDC power supply from a scavenged old Dlink router.

The code is much simpler because i don't have to deal with the power saving mode.

The connection too the #DR board and the sharp dust sensorare made via a DRF prototype board plugged on the top of the arduino uno.

The casing is made out of old outdoor halogen lamp. 2 years ago we have shifted form halogen too led and we have a all stock otoutdoor halogen lamp which are perfect to house outdoor electronic project. I replace the front glass by a piece of acrylic cut at the size of the front hole.

According to the sharp dust sensor datasheet, the ir led inside the sensor can attract insects if used outdoor at night, they recommend to shield the sensor against insect.

So i use a piece of metallic mosquito net to shield the sensor.
