Main Hardware

Model: 1510 Pelican Case

The case houses most of the hardware of the unit. It contains the battery, power supply, charge controller, router and the single board computer. The components of the case were carefully attached using materials such as velrco, wire-ties and bolts and nuts. The case was initially used for another project (Keck Water Monitoring Project), so some of the components i.e. the battery and charge controller were already installed. The posision of the charge controller was changed to a 'vertical mount' in order to make room for a secondary battery (if required) and to bring it closer to the power supply unit.

Model: EP2812 B.B. Battery

The battery is a 12V, 12Ah Lead-Acid rechargeable battery. It was chosen for its dimensions, capacity, operation temperature range and independent operational orientation (charges and discharges in any position). Even though the battery was not specially chosen for this project, its capacity was calculated to be sufficient for this project's hardware.

Model: Phocos CML10-2

This is a 10A, 12/24V charge controller specially chosen for its compatibility with the battery and ability to charge the battery using a solar panel. Due to the high power demand of the components and the significance this project, solar power was tested to be unreliable, especially at the deployment site where there are a lot of tall trees. Instead of a solar panel, a power supply was used.

Model: Mean Well SP-150-15

The power supply takes normal 115V AC and outputs 15V, 0~10A which is in the range of the output of a solar power panel compatible with our charge controller and battery. The deployment site is far from any buildings with a continuous supply of AC power, but luckily, there is a streetlight near by. Because the street lights use regulated power and only turn on at nighttime, the power supply charges the battery at night and then the battery powers the unit during daytime.

Model: Linksys WRT54G The router acts as a wireless adapter for the unit. It's firmware was upgraded to DD-WRT and it was configured to run in client mode.
