Arduino based themperature monitor with sms notifications.
- Arduino Leonardo ![Arduino image] (https://www.arduino.cc/en/uploads/Main/LeonardoNoHeadersFront_2_450px.jpg)
- SIM 900A GSM module
- 4 x Dallas OneWire thermal Sensors
- DS3232 RTC clock
Sketch periodicaly checking for themperature, if current measurings exeeds defined thesholds sms notification is composed and sended to speceifed arrays of phone numbers. After sending message GSM module make a call to pass trough "Do not distrub" mode on modern smartphones.
In SMS program trying to calculate some statistical information about measurements, like an:
- average temperatures for 3 time periods (5 mins, 10 mins, 60 mins)
- temperature changing speed
- forecast of elasped time to critical temperature
- SMS message is sending once a hour;
- Making call once a hour;
- GMS network checking;
- Thermo sensors working checking;
