IOT projects can be deployed in both sheltered as well as remote weather beaten locations. The following are some considerations while working on IOT projects. As you read through the considerations, you will realize that some of the main problems are power consumption, device security, and weather proofing.

Power source considerations include:

• Avoid batteries (unless unavoidable) as this will increase operational overhead of tracking and replacing. Instead, provide good quality power adapters (AC -> DC 3.3V, 60 - 170 mA) for powering the ESP modules.
• The ESP series Wi-Fi/GSM/GPRS/RF modules need to be powered from a stable battery power source. If electricity mains are not available, then use a rechargeable battery via Solar Panels.
• Battery lifetime enhancement via device/embedded software design: If possible, the Arduino boards and any Wi-Fi/GSM/GPRS/RF chips should be put to sleep mode to conserve energy.

Device enclosure considerations include:

• Devise a proper enclosure for the "Thing". Remember the 3D printing technique discussed in Chapter 6, Day 4 - Building a Standalone Device.
• Weather proofing is very important for enclosing remote devices. A suitable weather proof enclosure needs to be procured.

Device security considerations include:

• This is another major area of concern for outdoor locations and has to be dealt with in a conventional manner for ensuring physical security.
• Device identity/global positioning: In order to identify the location of a remote edge device and validate its identity, you will have to attach its identity either while flashing the embedded code, or use an SD card module with a public/private key to be used while communicating with the cloud.
