Waste Management

DESCRIPTION

Traditionally, waste collection has been performed on a fxed schedule. However,
regularly scheduled waste collection is not optimal as it does not account for
diferent individuals or businesses flling up their waste bins at diferent rates. Tis
means collection trucks must stop at each point on their route to empty each
waste bin regardless of whether they are full or not. It also leads to situations
where some waste bins overfow before the next collection schedule. By
implementing sensors embedded with LoRa Technology into waste bins and
using an intelligent low-power wide area network based on the LoRaWAN™
protocol, cities can signifcantly reduce their operational costs by streamlining
their waste collection routes and deploying trash bins only where they are
necessary

Fall Detection

DESCRIPTION

For the elderly, falling and not being able to get up or summon help is a very
scary prospect and happens frequently enough that it is a public safety concern
in certain communities. Fear of falling can keep elderly from participating in
activities, accelerate depression and decrease social activities all of which leads
to a reduced quality of life. IoT-based fall detection systems alleviate the fear
of not being discovered afer a fall which can help elderly to live an active,
normal life. By implementing a IoT-based fall detection solution comprised of
sensors and gateways embedded with LoRa Technology and an intelligent low
power wide area network based on the LoRaWAN™ protocol, elderly people can
live more full lives.

The Things Network

The Things Network is building a network for the Internet of Things by creating abundant
data connectivity, so applications and businesses can flourish.The technology we use is
called LoRaWAN and it allows for things to talk to the internet without 3G or WiFi. So no
WiFi codes and no mobile subscriptions.It features low battery usage, long range and low
bandwidth. Perfect for the internet of things.

myDevices Cayenne

Cayenne is the world’s first drag and drop IoT project builder that empowers developers,
designers and engineers to quickly prototype and share their connected device projects.
Cayenne was designed to help users create Internet of Things prototypes and then bring
them to production.
There are several major components in the platform:
Cayenne Mobile Apps  – Remotely monitor and control your IoT projects from the
Android or iOS Apps.
Cayenne Online Dashboard – Use customizable widgets to visualize data, set up rules,
schedule events and more.
