Temperature monitoring through Mobile or sim 300 modem

[sribangaram]

Dear Friends I want to start the project 48volts battery & room temperature monitoring and few appliance controlling like (ON &OFF) through Mobile or VISIONTEK GSM MODEM 82GM so Please send any body circuit diagram and required files :roll:

 

[tpetar]

Do you need monitoring over SMS ?

You can use voltage divider to measure voltages. For temp measurement you can use ADC for analog sensor.

For temp measurement you can use ADC for analog sensor.

 

[sribangaram]

Yes........Monitor SMS or PHONE CALL any thing but i want to monitor and if possible controlling few appliance also so please send the Circuit diagram and required files
Please excuse me for my language

 

[tpetar]

When voltage is on some level or temp reach some value then sms is send with some content like "voltage is 45V" or "temp is 35C !!!!" ?

 

[sribangaram]

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:

You can use voltage divider for measuring voltages over ADC of uC. In uC code you will define on what measured voltage level you will get what text content of sms message. The same is with temp sensor, you can use analog LM35 or digital DS18B20 just as example. When some event is happen with IF in firmware code then send sms to predefined user number.

I post earlier in some threads Trax SMS Box project, its located at this original address :
https://www.elektronika.ba/563/sms-box-projekt/

It handles SMS messages in pdu-mode so you don't need to worry about *many* things. You can talk to it over its «4-wire bus» and can be used for:

- Receiving sms messages (PDU -> TEXT conversion!)
- Sending sms messages (TEXT mode)
- Dialling a telephone number
- Hang-up a call
- Query call status
- Receive CLIP string
- Report a RING to microcontroller project (interrupt your uC program)
- Answer a call
- Set phone's date and time – not implemented yet
- Get phone's date and time – not implemented yet
- Check prepaid credit balance

Thanks to your Reply ......... But i don't Have that much of mind so if possible please send the diagram:sad:

Dear tpetar I am getting one diagram from edabord in your end can it's possible to modifying as my requirement **broken link removed**
Means thair is 8 temperature sencer's but i need 2 temperature sencer's and one 1 Battery volt sencer's and 1 AC voltage senser and 4 alaram data it's possible or not

 

[tpetar]

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. :smile:


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.

Dear tpetar I am sorry totally I am confused :shock: .............. ware I was connect Battery terminals for reading & ware I was connect Modem or mobile Please explain to me
I know I am very suffering you But Please excuse me

 

[tpetar]

This is just as like main concept about ADC for voltage and temp (if use analog temp sensor). This should be adjusted to your design.

 

[sribangaram]

Dear friend PIC18F4550 not available in my area but I am getting ADC 0808 ........... Can i use ADC 0808 ware PIC18F4550 place Please give me the confirmation I think that is also same work I am right :?:

 

[tpetar]

ADC0808 is just Analog to Digital Converter (ADC) he cant replace uC PIC18F4550, but you can use ADC0808 with like example 89S51 or 89S52 or some other cheap uC which you have in shops at your location.

 

[sribangaram]

Dear Friend how to check ADC0808 output

 

[tpetar]

There are several pages read all :

[sribangaram]

Dear friend I am getting AT89C51,PIC16F877 uc's ........ Can i use AT89C51 uc ware PIC 18F4550uc using place place?

 

[tpetar]

No, 89C51 and 16f877 have different ports, also firmware must be writen for them.

 

[sribangaram]

Dear tpetar I am getting pic18f4550 uc............... But my problem is my programmer not detect that uc Please give me suggestion
programmer :TOP2009 Universal Programmer

 

[tpetar]

I dont know I use PICKit 2 Clone. We must check does TOP2009 supports that uC for programming.

- - - Updated - - -

What programmer manual says what is uC supported list ?

- - - Updated - - -

What is manufacturer of that programmer or what is his web site ?

 

[sribangaram]

Dear friend programmer photo....... http://www.tradett.com/products/u38165p309265/top2009-universal-programmer-mcu-eprom.html
web site : www.top2048.com Please help anyway for program making

Dear friend one small request .......... Actually I want Connect to that Circuit
one temperature sensor, 48volts battery bank voltage reading sensor, AC Power(230v Red)(230v Yellow)(230v Blue), fuel level sensor these all Readers
Balance all are controlling purpose means (ON&OFF) Through Modem or Mobile so If any require to changing the program please change and send the HEX file why because Tu marrow I want to go 70Kms for program Burning purpose so Please Help me as soon as possible

 

[sribangaram]

Dear friend I am not getting the programmer for pic18f4550.............please help how can I burn the chip
