All smoke detectors use one of two types of sensors to detect fires. Ionization type sensors are best at detecting fast burning fires, while photoelectric sensors are generally better at alerting you about smouldering, or slow burning fires. You should have both types of alarms in your house. Smoke alarms such as the Nest Protect are designed to pick up both types of fires. Carbon monoxide and other gas detection. Even if you don't have a fire in your home, you can be suffocated by carbon monoxide. A good detector should also protect you against this.
