Sigfox car tracker
Sigfox's low-power network can't send YouTube videos or even a long email message, but the French company has found a lot of customers who need a cheap, battery-friendly network. This GPS sensor used in antitheft systems for cars periodically reports the location of a vehicle. Sigfox showed it and several other products off at the Mobile World Congress show in Barcelona.
Fire hydrant networked pressure monitor
Networking smarts can help firefighters make sure there's enough water pressure to actually fight fires. This pressure-monitoring system is built by Bayard, a French company that supplies most fire hydrants in France.
Burglar alarm backchannel
Thieves can try to defeat burglar alarms with jamming technology that blocks them from sending warnings using conventional mobile-phone networks. This alarm from Securitas Direct uses Sigfox communications as a backup alert channel to defeat the jammer.
Trash can with brains
Barcelona is installing trash cans that use Sigfox's network to report when they're getting full so the city can empty them sooner -- and not have to send collectors out to trash cans that aren't full.
Making dumb smoke alarms smart
The Otio Alert listens for smoke detector or burglar alarms and sends you a text message alert. In effect, it brings computing smarts to old-style alarms using Sigfox's network.
Better beer through wireless networking
Estella Damm is using Sigfox's network to monitor beer temperature at bars that may not be aware of malfunctions that could spoil the beer.
Connected beehive
Hipsters and environmentally aware companies like operating beehives. This one from Optibee reports wirelessly when honeycombs are getting full so they can be emptied.
