Emergency Call Button

Gandalf Greybeard wrote 01/26/2016 at 23:58 • 0 points

My elderly mother and I go to the gym at the same time. She heads off to the outdoor pool to swim, and I use a stationary bike. I would like to build or find an emergency alert that she can wear, which when the button is pushed, will send a signal directly to my cell phone. All of the Emergency buttons I have found, contact a base station, and may require a monthly fee. I want something that can send me a HELP signal, via bluetooth or wi-fi, that is waterproof, and doesn't cost a lot. Any ideas?

don't rely on internet connection for device like a panic button, you can make over bluetooth if range is close enough or NRF for wifi (but you need 2nd receiver to send to your phone) try with ziplock bag first. and you can buy the waterproof enclosure. or gopro enclosure

Thanks to all for the inputs. Following the Dash button hack threads, led me to a programmable button device called...
WIll have to put it in a waterproof bag. Found a pouch on ebay which mom can wear around her neck.

I can tell you from experience that wifi (at least and probably bluetooth as well) is strongly affected by even a shallow layer of water.

If the gym has wifi, you might be able to use an ESP8266 to get a signal out to your cell phone providers SMS API. Or to your own server which could then send an email.

Hello Gandalf,

maybe you could use the Amazon dash with a suitable water-proof enclosure?

as inexpensive as some of those buttons/base station versions are, maybe spend the 20.00 get one and find out what kind of signal it uses and modify it if need be. and or make an app to listen for that signal?

75 feet. And the outdoor pool is through a wall from the cardio room.
