The only smoke detector that can protect your family from everything: Flash fires, smoldering fires, carbon monoxide, and dangerous weather
Halo is a smart smoke alarm that does a lot more than sniff out fire. With a combination of sensors and Internet connectivity, it provides warnings about a variety of dangerous conditions both inside and outside the home.
Let’s start indoors. Halo uses five different sensors to monitor for hazards: two for smoke and one each for carbon monoxide, heat and humidity.
Why two smoke sensors? Because there are two kinds of fire, and a different sensor is needed to quickly detect each of them. Ionization sensors use an electrochemical signal to detect smoke from flaming fires, while photoelectric sensors respond when light from a focused beam is scattered by smoke from smoldering fires. Halo includes both, and combines them with data from its heat, humidity, and carbon monoxide sensors to tell the difference between a real fire and a cloud of steam or a pile of burnt toast, which might otherwise trigger a false alarm.
When the device does detect fire, or a dangerous buildup of invisible, odorless carbon monoxide gas, it doesn’t just burst into a piercing electronic wail. The alarm mode is firm but progressive, starting with a voice alert that tells you what kind of hazard has been detected. It also begins to glow with color-coded LEDs that pulse faster as the danger increases, and slower as conditions return to safety. At the same time, notifications can be pushed to your mobile device so you’ll know something’s wrong even if you’re out of the house.
But hazards don’t always come from within, which is why Halo also connects to civilian alert systems from the National Weather Service and other agencies. Depending on your preferences, it can warn of dozens of conditions from tornados to flooding to child abductions and civil emergencies.
Halo is designed to be hardwired into a home’s electrical system with a rechargeable backup battery, but can also run on batteries alone. Like other smart smoke alarms, it provides mobile notifications instead of the annoying low-battery beep — which accounts for nearly one in eight fire deaths, as alarms deactivated in frustration fail to operate. Halo connects over Wi-Fi and Zigbee and can be integrated into a variety of smart home systems, such as HomeKit,OpenHome, and iControl.
The designers behind Halo are raising funds on Indiegogo through June 18, and hope to start shipping their alarms in the fall. Potential backers might be comforted to know that the device has already been field-tested during a controlled burn with the St. Stephens Fire Department in Catawba County, North Carolina. While the plastic housing melted, the electronics continued flashing and sounding the alarm until firefighters came to the rescue.
