The intercom consist of two units; the outdoor and indoor. The outdoor unit was used by the guest to communicate with the household owner to notify them of their presence at the door while the indoor unit was used to respond to the call. The transceiver module transmits and receives audio signals between the two units, while ATmega328 handles the conversion of the signal from analog to digital during transmission and vice-versa at reception. The outcome of the test and analysis carried out on the developed prototype shows that it is user-friendly, consumes less power, and also proves that it is a cost-effective solution that can be affordable and made to be readily available to the consumer.<\/jats:p>","DOI":"10.12720\/jcm.16.9.379-385","type":"journal-article","created":{"date-parts":[[2021,10,20]],"date-time":"2021-10-20T08:41:57Z","timestamp":1634719317000},"page":"379-385","source":"Crossref","is-referenced-by-count":2,"title":["A Cost-Effective Two-Way Household Wireless Door Intercom System"],"prefix":"10.12720","author":[{"name":"Department of Electrical, Electronics and Computer Engineering, Afe Babalola University, Ado-Ekiti, Nigeria","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Temitayo O.","family":"Ejidokun","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oluwole J.","family":"Oke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ibukun M.","family":"Omitola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toyese","family":"Oduneye","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4977","published-online":{"date-parts":[[2021]]},"reference":[{"key":"ref0","unstructured":"[1] A.
