Sensores son en total 4: 2 sensores MPX5010 para los dos depósitos de aguas limpias, el MQ2 que es el sensor de Gas y el inclinometro. El de agua grises es solo una boya con un interruptor, este deposito no hace falta saber el nivel, solo hace falta saber que esta lleno para ir a vaciarlo.
A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
