PIC-based wateralarm with SMS function
Some of you fellow readers and subscribers may have noticed the video on Youtube of our PIC-based SMS Wateralarm. I went on vacation and forgot everything about it, especially I forgot to write about it in here – so I think it’s time.
The project is a school project about Water, in the class called “Technology”. We discovered the growing problem about flooding of houses near rivers and lakes, and thought it would be a brilliant idea to invent a system that could alarm the owners by an SMS, if flooding should occour.
So we decided to try to make a such system using a PIC, a chineese GSM evaluation board (SIM300) and our electronics knowledge. This ended up in a working system as you can see in the video below.
The system consist of the following parts
- Microprocessor unit – PIC16F690
- GSM Module – SIM300
- Alarm – Buzzer
- Numeric keypad – Matrix keypad
- Water detector – Darlington pair
As this is a school project, actually an exam project, we also made a report. Though this report is in danish, exept for the first page, so you would have to translate it or just look at the images. The report can be downloaded here: PIC-based wateralarm report
Though in this PDF-version of the report the schematics isn’t included, though they are listed as some of the annexes.
Instead, the schematics of the system can be seen in the following images.
