Wisdom of the Crowed Final Review High Speed Digital Systems Lab

Herds owners deal with control difficulties. It reflects in daily problems, for example: Herd’s members Stealing Following health status Real time monitoring.

Herd’s members would wear the smart collar Each smart collar receives GPS and sensors data The collars share data through WIFI Real time data will be transferred to the base station Owners will have an easy way to control their herd.

WIFI Cellular GPS & Sensor

Main goal - design a stand alone unit, supports the following: Receive and process GPS and sensors data Receive and process GPS and sensors data Communicate with a similar unit through WIFI Communicate with a similar unit through WIFI Send data from a single unit (Master) to “base station” by cellular communication Send data from a single unit (Master) to “base station” by cellular communication

Hardware : Arduino Nano v3.0Tmega WIfI module ESP8266 GPS module U-blox NEO 6M Potentiometer (“Heat sensor”) Cellular module – GPRS shield, SIM900 Software : Arduino programming language C programming language

Cellular communication requires more power then WIFI Cellular communication requires more power then WIFI The user will be updated on demand (power preservation) The user will be updated on demand (power preservation) The user will be updated immediately in case of critical situations (high temperature, WIFI lost connection) The user will be updated immediately in case of critical situations (high temperature, WIFI lost connection)

SLAVE will receive data from it’s sensors every 10 seconds SLAVE will receive data from it’s sensors every 10 seconds SLAVE will send data to the MASTER every 10 seconds SLAVE will send data to the MASTER every 10 seconds

MASTER will send data to the owner on demand MASTER will send data to the owner on demand MASTER will send data to the owner immediately in case of critical situations MASTER will send data to the owner immediately in case of critical situations

Using SMS instead of the server Using SMS instead of the server Separation between master and slave Separation between master and slave No Location warning No Location warning

Not enough memory on the Arduino board Not enough memory on the Arduino board  Using AT commands instead of Arduino’s libraries Server on Technion’s network Server on Technion’s network  Using SMS messages to communicate with the owner Listen to GPRS module isn’t continuous Listen to GPRS module isn’t continuous  Store incoming SMS on the SIM card

Scenario 1: High Temperature – Slave 1.“Increase temperature” (change resistance) 2. Slave’s temperature rise on the slave screen 3. Slave’s temperature rise on the master screen 4. Warning SMS to the owner

Scenario 2: High Temperature – Master 1.“Increase temperature” (change resistance) 2.Master’s temperature rise on the master screen 3. Warning SMS to the owner

Scenario 3: Owner’s Demand 1.SMS from the owner 2.“New SMS received” on the master screen 3. Full status SMS to the owner

Scenario 4: Lost Connection – Slave 1.Turn off the slave board 2.Fail to send new data on the slave screen 3. “Lost Connection” on the master screen 4.Warning SMS to the owner
