what is Gsm Gprs module embedded

What is the use of GSM or GPRS module interface with Microcontroller 8051?

The embedded system is an electronic component, which we make a mini or major projects. In the embedded system have developed tools kit, which is PCB AT89C51 board, RF module, Zigbee module, GSM or GPRS module and Wi-Fi connections and so on…

The developed projects tool kit was essential for the project implementation. If you didn’t found any device in market, then you can try to develop the device.

Let’s take an example: If you want to wireless communication of three phase submersible motor pump want to operate as ON and OFF, with your mobile phone or remote.

If you have a agriculture in your hometown, and also have submersible motor pump for water to the crop plantation in the agriculture field i.e., irrigation requirement implementation. If you are staying out of station or long distance at the other place, then you can prefer this GPRS module or Zigbee module both or wireless communication, but the range of distance of GSM / GPRS and Zigbee were different.

If you are staying out of station then consider the GSM / GPRS module, if you are staying near the place of range between 1feet to 1km then, consider module of Zigbee.

You need SIM chord with recharge balance to operate the GSM / GPRS module is required. The communication modules can operate through commands with SMS in your mobile phone give below few commands for your reference. It will STOP and START the submersible motor pump through SMS commands for paddy or any type of water required crop cultivation to get good production from agricultural fields.
