Problem -

Every year, in late summer and fall, thousands and millions of backyards, lawns, golf courses and open grass fields suffer from rodents and birds digging the ground in search for earthworms, soil-dwelling insects, and insect larvae (grubs) ruining the grass and leaving behind large patches of loose turf. This is not only a huge problem for the grass farming industry but also for every backyard ruining the aesthetic pleasingness and plants grown on the lawn. The current deterrent methods are technologically naive including of just a motion sensor, lights and loud sounds which can leave the user unaware of the type of rodent affecting their lawn, loud noises at night and a deterrent that does not prevent lawn digging.

Solution -

We are proposing a rodent detection and deterrent system which comprises of many parts. Firstly using infrared and ultrasonic sensors on a rotating servo, we would detect for any rodent outside of the usual landscape of the lawn the device is placed in. The PI camera system would simultaneously work to take a clean shot of the rodent/bird and store it in the file system. If recognized to be a ground digging rodent, for the actual deterrent, our colored lights and localized speaker beeps would go in the direction of the rodent/bird rather than just in 1 direction like the previously commercialized methods. This would ensure rodent deterrent and also tell the user what type of animals are responsible for digging their lawn.

Criteria For Success -

To test for this method, we would set up our system on a surface and test using props of different types of animals. We need to showcase that the sensors can detect irregularity and movement outside of the known landscape, can take a photo of the rodent and then classify the rodent and then also on moving servos, send localized beeps and colored light beams towards the rodent to scare it away and realistically prevent it from digging the ground.

Interactive Proximity Donor Wall Illumination

Featured Project

Link to the idea:


The Donor Wall on the southwest side of first floor in ECEB is to celebrate and appreciate everyone who helped and donated for ECEB.

However, because of poor lighting and color contrast between the copper and the wall behind, donor names are not noticed as much as they should, especially after sunset.

Solution Overview:

Here is the image of the Donor Wall:

We are going to design and implement a dynamic and interactive illuminating system for the Donor Wall by installing LEDs on the background. LEDs can be placed behind the names to softly illuminate each name. LEDs can also fill in the transparent gaps in the “circuit board” to allow for interaction and dynamic animation.

And our project’s system would contain 2 basic modes:

Default mode: When there is nobody near the Donor Wall, the names are softly illuminated from the back of each name block.

Moving mode: When sensors detect any stimulation such as a person walking nearby, the LEDs are controlled to animate “current” or “pulses” flowing through the “circuit board” into name boards.

Depending on the progress of our project, we have some additional modes:

Pressing mode: When someone is physically pressing on a name block, detected by pressure sensors, the LEDs are controlled to

animate scattering of outgoing light, just as if a wave or light is emitted from that name block.

Solution Components:

Sensor Subsystem:

IR sensors (PIR modules or IR LEDs with phototransistor) or ultrasonic sensors to detect presence and proximity of people in front of the Donor Wall.

Pressure sensors to detect if someone is pressing on a block.

Lighting Subsystem:

A lot of LEDs is needed to be installed on the PCBs to be our lighting subsystem. These are hidden as much as possible so that people focus on the names instead of the LEDs.

Controlling Subsystem:

The main part of the system is the controlling unit. We plan to use a microprocessor to process the signal from those sensors and send signal to LEDs. And because the system has different modes, switching between them correctly is also important for the project.

Power Subsystem:

AC (Wall outlet; 120V, 60Hz) to DC (acceptable DC voltage and current applicable for our circuit design) power adapter or possible AC-DC converter circuit

Criterion for success:

Whole system should work correctly in each mode and switch between different modes correctly. The names should be highlighted in a comfortable and aesthetically pleasing way. Our project is acceptable for senior design because it contains both hardware and software parts dealing with signal processing, power, control, and circuit design with sensors.
