Suggestion for a Project

thanku sir.. i tried to edit it but its not coming.. thanks for the suggesion..thanks a lot

GA for coming back and saying "Thank you."

Not many who come here with a question do that.

Look at the microcontrollers and sensors at sparkfun.com, they have a cellphone adapter for about $50 US...they also have Zigbee standard transmitter-receiver link pieces you would need. What you described to do parts cost appx. $350-400 USD and software time, lots of examples of use of same at Auduino website.

thanks you sir

I have been using microcontrollers and Zigbee networking parts to link them together and thought it might have been a mistake as the GSM units seemed more economical...the controller might be, but then each device requires a cell phone, and that would require me to spend an additional $15 per month per unit, which makes GSM more expensive as my links are all less than 2km.

This is possible. Cost will be prohibitive for any Farmer. There are remote monitored Energy meters available with data acquisition. These meters are to be located to in the motor circuits. These meters will capture all the data like current,voltage ,power and energy etc., after capturing these meters will transmit data .The data has to be linked to particular channel/server, from the server the data can be seen by the Farmer remotely in smart mobile phones.

thank you sir.thanks for the suggesion

the method which you said was developed by a person from gujarat. he just started basic version just to on and off of motor. i have gone through it.

well however thanks for the support . thanks a lot sir

In this method, you can have mini PLC located near the motor, which can receive SMS to switch on or switch off the motor. This PLC will have modem module to receive the SMS and act. This becomes slave station. Where as the requirement is to transmit the data then it should be Master.

You want to remotely control and monitor irrigation pumps in rural India?

My gut feeling is that this is futile but I might be wrong....

First step would be to determine and document exactly how the farmers are operating their remote plant now, what their security concerns are, how reliably this remote plant operates, what the costs are associated with their operations and so on...

then......

Try to improve on that.

I'd be betting that most pumps in rural India are diesel driven, relocated very frequently then brought home and locked up every evening.

yes sir i have gone through 6 villages in prakasham district in ap they have such kind of problem of on and off and motor failure etc problem after seeing these things i got this idea. according to my sense its not going to be futile...still there are many places they don't have proper motor and you are saying remote motor.they don't have awarness of such techniques.as a citizen can't i develop them by my small idea ?

it might look silly but we can't neglect right :).

thanks for the rply....

Does not seem silly to me.

However, without walking through rural India with YOU, I have no idea how to fix whatever problem there might be. I usually find that the problem is obvious when I see it...and it might not be the problem I thought it might be. For instance, I never thought of bringing pumps home like Wal suggested.

You can make an auto live phase selector using two contactors. The 24 hour timer that is easily available (or you can design one) can be used to switch on the pump(s) at predetermined time and duration.
