# BIKE THEFT LOCK & CHAIN DETECTOR (UPDATED)

# PROBLEM
In the Champaign-Urbana area, it is estimated that around 856-1070 bikes are stolen each year (bikelab.com), with most perpetrators going unapprehended and missing bikes seldom recovered. Bike theft often goes unnoticed, especially if the crime occurs at night or with few witnesses.

# SOLUTION

The proposed solution is a cable bike lock that detects when the cable is cut by passing current through the cable and building a sensor to detect an open circuit. When the cable is cut, our cameras positioned on the cable and bike will record images that may potentially identify the criminal. The cable will also send out a signal to an alarm, as well as relay all this information to the user via bluetooth/Wifi connection.

# SOLUTION COMPONENTS

## SUBSYSTEM 1: OPEN CIRCUIT DETECTION

This system will pass a small current through the cable, using the cable and analog components to create a circuit. When the cable gets cut, the circuit would open and this would send a signal to the microcontroller indicating that theft is taking place.

## SUBSYSTEM 2: IMAGE CAPTURING VIA CAMERA

Once the microcontroller detects the open circuit, the camera modules connected to the microcontroller will take an image that the user will be able to receive via bluetooth connection, potentially providing key evidence to identify the perpetrator.

## SUBSYSTEM 3: SOUND ALARM

When the inductance is changed, the microcontroller should send out a signal to electronic alarm devices to alert the user or anyone nearby to someone trying to cut through the cable. The user will then receive a notification on their phone with an option to turn off the alarm, or the alarm will sound for a set amount of time.

# CRITERION FOR SUCCESS

Our device will be able to:

- Detect when the cable is cut
- Send a signal to sound an alarm when the cable is cut
- Take a picture as the theft is being attempted
- Relay the images and alarm sounding to the user's phone

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!
