Abstract

DISPOSITIVO SENSOR. A presente invenção refere-se a um dispositivo sensor que pode ser configurado para a detecção de um nível de líquido, uma concentração de uma substância específica incluída no líquido e uma temperatura do líquido. O dispositivo sensor pode compreender um substrato, um eletrodo de nível configurado para ser disposto sobre o substrato e detectar o nível, um eletrodo para qualidade de líquido configurado para ser disposto sobre o substrato e detectar a concentração, um eletrodo de temperatura configurado para ser disposto sobre o substrato e detectar a temperatura, e um eletrado de referência configurado para ser disposto sobre o substrato e manter um potencial elétrico de referência. O eletrodo de referência pode ser disposto pelo menos entre dois dentre o eletrodo de nível, o eletrodo para qualidade de líquido e o eletrodo de temperatura.
