I need someone to design and write code for a simple unit which can be connected to a GSM / GPRS module to send an SMS when a set point is reached.
4 Analogue Inputs (Resistive)
2 Analogue Inputs (4 - 20mA)
6 Switched Inputs
a) Front end software needed for setting set-points & target mobile number.
AI1 used for Oil Pressure --> When Oil Pressure goes below 1.2 bar an SMS to be sent to target number --> Message to read "Warning ! Oil Pressure 1.2 Bar".
1.2 bar can be set using Front end software.
Trigger on Higher than or Lesser than can be also set by Front end software.
Note: Unit NOT to include a GSM module. To work with any GSM module. Board level + Source code is good enough.
