There are all sorts of useful applications for sensors that can connect to the cloud, from logging data to sending alerts to disseminating information. We built a connected sensor Internet of Things application that logs temperature data and sends email alerts to specified individuals when the temperature falls outside an expected range. This video explains how it works:
Although we chose to use a temperature sensor here, any type of sensor could be used in a connected application like this one. We wired our temperature sensor to a Samsung ARTIK 10, which we programmed to email us whenever the temperature that the sensor was reading got too hot or too cold. We also created a simple PHP web app to let us update the temperature thresholds that we were using for our alerts.
