# Problem:
For now, because of the kind people from all walks of life and the existence of many adoption agencies, it is difficult for us to see stray animals on the street without a fixed place to live, but this is not absolute! Because in my community, I always see a lot of stray cats, regardless of age and species. When I meet them, they are not necessarily alive. The cold and food shortage will threaten their lives. And every time I want to help them, I can't just happen to be able to provide them with food. Even if I can give them food, the stray cat population and its offspring will continue to wander. So my idea is how to help them live better. I plan to build a portable stray cat rescue station that can be placed in areas where stray cats are present to provide them with warmth and food.

# Solution:
My solution is to design a wireless constant temperature device that can detect the temperature in the cat's nest at all times to determine whether the heating device is turned on and off. Then equip it with feeding equipment, and detect whether there is enough food in the cat's food bin. Through wireless data transmission, maintenance personnel can decide whether to add food to the equipment according to the data.

This device includes the following modules:
Power supply module: as the power source of the entire device and other subsystems
Heating module: to control the device temperature
Main control module: transmit real-time data of the device
Casing and heating layer: enhance the warmth of the device at the physical level

#Solution components:

## Subsystem 1: Power supply module
Overview: This subsystem uses solar panels and lithium batteries to realize the device power supply system. While avoiding the trouble of replacing batteries, it can also realize the convenience of this device and can be installed outdoors. It is also conducive to the operation of subsystem 2 (heating module) at night.

Design:
Power generation method: solar panels can generate solar energy outdoors
Power storage method: use lithium batteries of suitable capacity to store electricity

## Subsystem 2: Heating module

Overview: This subsystem automatically controls the temperature in the device through heating equipment and temperature and humidity sensors

Design:
Heating method: heating by laying heating wires in the device
Temperature control method: use temperature and humidity sensors to detect whether the temperature in the device is lower than the set value and turn on the heating device, and the temperature can be monitored in real time through subsystem 3 (main control module)

## Subsystem 3: Main control module

Overview: Detect data in the device and transmit data wirelessly to the receiving station

Design:
Transmission method: Use LoRa devices for transmission to ensure that data is obtained when there is no network in the wild.
Reserve detection: Use pressure or infrared sensors to detect food residue
Power monitoring: Real-time recording of battery remaining power
Activity detection (optional): Infrared sensor detects cat entry and exit (optional: camera monitoring, but it is not suitable for no network and the price is higher.)

## Subsystem 4: Shell and heating layer

Overview: Use physical methods to assist and strengthen the role of subsystem 2 (temperature control module), and reduce power consumption.

Design:
Shell: Waterproof plastic board, aluminum plate or 3D printing material, and a metal frame about 10 cm above the ground to prevent rainy weather
Inner layer: Warm and fireproof foam board or other insulation material

# Criterion For Success:
This design would be considered successful if
The heater will automatically turn on and off when the temperature is within the set value range
When there is not enough food in the feeding bowl, it will automatically dispense food
Ability to obtain various real-time data on the LoRa master station

Our project is to be a reliable, robust, and intelligent irrigation controller for use in areas where reliable weather prediction, water supply, and power supply are not found.

Upon completion of the project, our device will be able to determine the moisture level of the soil, the water level in a water tank, and the temperature, humidity, insolation, and barometric pressure of the environment. It will perform some processing on the observed environmental factors to determine if rain can be expected soon, Comparing this knowledge to the dampness of the soil and the amount of water in reserves will either trigger a command to begin irrigation or maintain a command to not irrigate the fields. This device will allow farmers to make much more efficient use of precious water and also avoid dehydrating crops to death.

In developing nations, power is also of concern because it is not as readily available as power here in the United States. For that reason, our device will incorporate several amp-hours of energy storage in the form of rechargeable, maintenance-free, lead acid batteries. These batteries will charge while power is available from the grid and discharge when power is no longer available. This will allow for uninterrupted control of irrigation. When power is available from the grid, our device will be powered by the grid. At other times, the batteries will supply the required power.

The project is titled S.I.P. because it will reduce water wasted and will be very power efficient (by extremely conservative estimates, able to run for 70 hours without input from the grid), thus sipping on both power and water.

We welcome all questions and comments regarding our project in its current form.

Thank you all very much for you time and consideration!
