The world of smart technology is expanding daily. From glasses and phones to cars and homes, smart systems are being implemented into almost anything man kind can create.Particle Photons
On a small scale doll house, Particle Photons are used to create a smart system for a home. In this system, motion sensors act as switches for lighting of different floors of the doll house. LED light demonstrate the lighting of the house in specific rooms. Motion sensors placed on each floor detect motion on that particular floor and turns on the LED lights corresponding to that motion sensor and floor. The use of more motion sensors in each individual room can improve the system and more precisely control the lighting in a house.
The photons also receive data from a BMP180 temperature/pressure sensor that acts as the home AC unit. Once the temperature of the house reaches a defined temperature, the fan (AC) will cut on. Once the fan (AC) has cooled the house to the defined temperature, fan will cut off until the temperature passes the defined threshold again. Feedback
Temperature and control system feedback are implemented through the console.particle.io and ThingSpeak. This continuously running smart system has multiple functions.
The PublishSensorInfo function reads the BMP180 sensor and stores it so that the control of the fan (AC) can be executed in the loop and published to another photon that powers the fan (AC)Outputs
The readTheSensor function reads the outputs from the PIR motion sensors.
The reportTheData function takes the outputs from the readTheSensor function and declares where there is movement in the doll house and which floor of the house the motion was detected in.
The fanControl function reads the information from the particle.subscribe and turns the fan on or off if the temperature reaches the threshold.
ThingSpeak is used to graphically represent the temperature readings over time as the system continuously runs.
