Have you ever left your house and accidentally left your lights on or forgotten to fix the thermostat? With our sensor set up, you'll be notified when you leave lights on accidentally or when your house becomes too hot or cold. In order tofix this we used a sound sensor, a light sensor, and a thermometer and they all communicate with each other in order to keep track of everything.
The sound sensor will be placed by the front door and will listen for the sound of the front door closing. When it reads the sounds that the door has closed it will send a signal to the photo-resistor and the digital temperature sensor.
Once the big sound sends a signal saying that that the door has been closed, It will then trigger the light sensor which will detect if the lights have been left on. If the lights are turned off then nothing will happen, but if the lights have been left on it will then send a signal back to the Particle Argon connected to the big sound sensor saying that the lights are on.
When the Thermometer receives the signal from the big sound sensor, it will trigger and will start reading the air temperature. The optimal temperature of the air sits between 70°F and 74°F. If the temperature does not fall within the optimal range then a signal is sent to the Particle Argon connected to the big sound sensor. Once the Argon isconnected to the big sound sensor receives signals saying that the lights are on or that the temperature is outside the acceptable range the Argon will send emails to the user alerting them that the lights are still on or the air temperature is not in the acceptable range. This way if you accidentally leave the lights or the heat turned on you'll be able to receive an email notification before you even leave your driveway.
Live Data Graphing
Below is a visual representation of and a link to the data acquired by the digital temperature sensor over the span of about 24 hours. The data is Thermistor resistance values, so higher values correspond to lower temperatures. For this sensor, 1800 corresponds to about 70 °F.
