Hi,
What parts do I order to make the following 3G switch?
Here is a description on what I want the “remote switch” to do:
When the “remote switch” receives a SMS text “ON”, the digital output goes high, then sends an SMS text “Confirmed ON”.
When the “remote switch” receives a SMS text “OFF”, the digital output goes low, then sends an SMS text “Confirmed OFF”.
Notes:
I want any phone to operate device and not have to set up “authorized phone numbers”
Digital output will run a 12vdc 100ma pump (or similar).
Device is battery powered so energy efficient design is needed.
Cellular signal strength should be able to be checked by sending SMS text “signal” and receive a response (or similar method).
I need to be able to change the response sent by the device from “confirmed ON” or “confirmed OFF” to something else. The least costly way to go.
I was looking at your Product Code : RB-Ite-170 ? Do I need an Arduino Uno (or similar)?
Thanks,
Jim
Hey Jim,
Here are answers to your questions:
A microcontroller, a 3G module compatible with your microcontroller and your 3G provider. You can check your provider’s technologies and frequencies used here. Please note this is only for reference and you should always contact your provider directly to get up-to-date information about what modules are compatible.
Yes, it is a shield and requires an Arduino to function properly.
We recommend that you do not worry too much about the battery at first and instead focus on getting the integration working. Once you have a working prototype, then you may want to start integrating better the various power management features of your microcontroller and 3G module.
You may also want to check the product under RB-Itb. They offer plenty of good solutions for 3G modules (and even 4G/LTE) and they have tutorials and blog posts, too.
Sincerely,
Will your SIM5216J 3G GSM GPRS Arduino Shield work on T-Mobile in the USA? What is the difference between the 5216a and that 5216J?
Hey,
If you are trying to use a service that requires WCDMA, then it will most likely not wok as the SIM5216J is meant for a different region.
You can see the details on compatible frequencies on the product page under Specifications.
You can check the reported frequencies for various wireless service providers here.
Please note this information is only for reference; you should always check with your service provider for more details / confirmation.
Please see the Specifications of the RB-Ite-170 for details. Aside from the frequencies used, the chips are the compatible with each other.
Sincerely,
