Temperature monitoring through Mobile or sim 300 modem

You can make PICKit 2 Clone.

Please send the diagram

You can find on circuit and other needed material in edaboard threads, such my post in this thread : https://www.edaboard.com/threads/244133/

That PICKit2 have EEPROMs whic allow programmer to memorize firmware and can be used without PC. Or you can make standard PICKit2 Clone without EEPROMs search edaboard threads.

Dear friend I have to purchased PICKit 2 Clone and burned the program and connected to pc detected the IO board
So please suggest me how I will connect the temp sens, Battery voltage sens, Ac voltage sens and modem

Dear Friend I have to don this


Re: Temperature monitoring through Mobile or sim 300 modem
No need for that you can easely use many analog or digital temp sensors and measure voltages with your projects.


Do you have some programming uC knowledge ?

Thise days is high temp at my location, I dont like high heat. There are some peoples I think they are aliens in humans costime they love heat of over 40C. I put brain on idling to avoid overheating, as cooling liquid I use cold beer.


You can use lots of uC, I use ATMega32 to log 8 temp sensors, or you can use PIC18F4550 in example like this, of course you can adjust source code to your needs :

**broken link removed**







On each ADC you can put one LM35 or measure voltages. For your needs you need to use voltage divider for high voltage.

This is just one example.

Sometimes if PC is included in project you can have PC application which send email, when email received in inbox at ISP, ISP send SMS notification with subject of email which containts temp, voltage, and other informations. Or if you have some nice phone like my favorite Android Samsung Galaxy S 2 or 3 you can have instant notification of received emails.


Now pLease tell me what my next step :-|:-|:-|

Next step depends where you standing, if you are on cliff next step forward wouldn't be smart.

Did you get programmer for PIC18F4550 ?

Friend I have to don the program and IO board also working well with the PC ............ Now my requirements is MODEM connection Slave side means (in my shelter work place) and another modem to connection in host side means(in my home for data logging and controlling purpose ) please see the thread's #5,6,7

Yes My Battery bank voltage is 48volts so when AC(RAW230 Volta's) power has to be gone that bank discharge slowly when it will reach the 45 volts that time I want to start dg(diesel generator)
and second Issue normal room temperature is 28 to 30 degrees when it will reach the 40 degrees that time I want to start AC(air conditioner) these all work is want to do mobile through so please send suitable circuit diagram for this work Please understand my language I am poor in English writing:sad:

Hi Sribangaram,

See this example which keep lead acid battery on float cherge voltage. If voltage go up over 13,8V charger is off, when voltage go below 13,8V charging is on. In your case on similar way you can set if voltage reach 45V or below start generator (output pin high). Example is written in MikroC for PIC and use this as example. The same situation is with temp, you can use analog LM35 read ADC steps (voltage) and set conditions and outputs.....

Dear Friend I don't know program wright :-(

FRIEND
There is 6 An log In puts Ok............ I required ....... 1 AN LOG BAT VOLTAGE(DC VOLTAGE), 2 AN LOG ROOM TEMP, 3 AN LOG AC VOLTAGE(1), 4 AN LOG AC VOLTAGE(2), 5 AN LOG AC VOLTAGE(3), 6 AN LOG AC VOLTAGE(4) NEXT RB'0' to RB'7' AND RD'0' to RD'7' are Out put's Means 16 controllers and MODEM are ETHERNET connection for Remote controlling purpose I am right?

Hi Sribangaram,

You should start learning programming. Start step by step, for some time you will learn lots. Additional programming requires time and attention.

Lets see

1pin ADC to measure battery voltage
1pin ADC to measure room temperature LM35
1pin ADC to measure AC voltage
1pin ADC to measure AC voltage
1pin ADC to measure AC voltage
8pins PortB all digital outputs

You need 5 input pins for ADC, and 8 pins for digital outputs, plus modem controls.

I suggest to start one by one, first search EDABoard existing threads to see how to measure voltage and LM35 using ADC. Search for voltage dividers, mains voltage measurement using ADC,...

I already give you example for voltage measurement.
