Hearing impairment affects everyone within the impaired person’s vicinity. A person’s inability to hear a doorbell could mean a missed parcel delivery, inconveniencing both parties since the carrier often makes a second attempt before returning the parcel to the hub for pickup. The sufferer might not hear a family member’s attempts to get their attention after becoming accidentally locked out of the house.
Solutions already exist to resolve this issue, but can require great expense to the sufferer. Electrical outlets can be tied in with the doorbell, but necessitate additional wiring. In a finished home, sheetrock walls must be cut open to expose pathways for electricians to run wire to an outlet to make a desk lamp flash when the doorbell rings and can be cost prohibitive. Inexpensive aftermarket solutions also exist, but are often bulky, unreliable, and might not meet a person’s exact needs.
The Arduino Doorbell Alert System (ADAS) utilizes radio frequencies and requires no additional wiring to a home, installs with relative ease, and provides an electrical outlet to power a lamp.
Here is a picture of the finished prototype:
