[ed. I suspect we'll see a virtual flood of these types of devices as the Internet of Things becomes more of a reality.]
Earlier this month, as Google was snatching up the smart-thermostat maker Nest for $3.2 billion, a lesser known home sensor company made its own announcement. SNUPI Technologies, a Seattle startup, said it had garnered $7.5 million in funding. That might be pocket change compared to the Nest deal, but it was a significant endorsement just ahead of SNUPI’s first product launch: a low-power wireless sensor network called WallyHome that tracks humidity, water leaks, and temperature throughout a building.There are already many home monitors on the market; some, such as Lowe’s Iris Home Management System and a water leak and flood sensor from General Electric, are even wirelessly networked. What makes WallyHome novel is its use of a low-power communication scheme that lets sensors send data back to an Internet-connected base station over significant distances and through obstructions like walls and floors while sipping power from a coin-cell battery.
SNUPI cofounder Gabe Cohn believes this long-distance, low-power approach will endear the product to homeowners who want a reliable sensor network that requires little maintenance and can be installed easily. The base station plugs into a wall outlet and an Internet router via an Ethernet cable. Six wireless sensors are placed in leak- or humidity-prone areas, such as behind a toilet, under a dishwasher, or near a sump pump. And each sensor’s battery should power the device for up to 10 years without a replacement, Cohn says.
