As portas automáticas utilizam vários métodos automatizados para abrir e fechar, dependendo da sua utilização e colocação. Estes métodos requerem normalmente um mecanismo de sensor em ambos os lados da porta e por vezes incluem um sensor secundário para segurança. As portas com activadores de sensores de pressão (micro-interruptores) têm um grande calço colocado à frente da abertura. A almofada funciona como uma balança, detectando a quantidade de peso colocada sobre a almofada num determinado momento. Quando o tapete detecta um peso suficientemente pesado para representar uma pessoa, a porta abre-se. Uma vez que o tapete também reconhece quando uma pessoa sai do tapete, o mesmo mecanismo pode manter a porta aberta e fechá-la. Os sensores de pressão também são utilizados como mecanismo de segurança, como os que revestem a parte inferior de certas portas. Se a porta começar a fechar-se sobre um objeto resistente, os sensores avisam a porta para se abrir. Como resultado do avanço da civilização e da modernização, a natureza humana exige mais conforto para a sua vida. O homem procura formas de fazer as coisas com facilidade e que lhe permitam poupar tempo. Assim, as portas automáticas são um dos exemplos que a natureza humana inventa para trazer conforto e facilidade à sua vida quotidiana.
