Hi all! Here’s the new project where I’m working a couple of days. Since I develop the SIM900 module and test it, I don’t work with it. Also, I’ve got at home some samples of the MCP2200 USB bridge that I want to test it. So make an USB interface for this board was the perfect idea! This allows to use the SIM900 board with a PC, Raspberry or similar, with the plus of no need external power supply or control signals. Just plug the USB cable on the board and start communicating with the world!

This project demonstrates how to design a wireless electronic notice board using SST89E516RD-40-C-PIE microcontroller. The notice boards are important in public places like railway stations, parks and airports. Presently almost all electronic notice boards are designed using wired system. One of the drawbacks of the design is the system’s flexibility in terms of placement. The aim of this project is to develop a wireless notice board that can be installed in any public areas and will display the latest information sent from the user’s mobile.

The above circuit consists of Microchip Technology’s SST89E516RD-40-C-PIE microcontroller, GSM module, level converter and 16×2 LCD. The LCD is connected to P1.0 and it is used to display message. The GSM module is connected to the SST89E516RD-40-C-PIE microcontroller through the MAX232 IC. Only four data lines are required to display the data, which are connected to P1.4, P1.5, P1.6 and P1.7 respectively. In order to communicate with GSM, some AT commands are sent through the serial connection (UART Protocol). The module requires 9600-baud rate. The GSM modem is duly interfaced through level shifter IC for establishing RS232 communication protocol to the microcontroller. The message received is sent to the microcontroller that further displays it on electronic notice board, which is equipped with a LCD display. It is interfaced to a microcontroller from 8051 family duly powered by a regulated power supply.

This GSM based e-notice board has various applications used in several domains including banks, stock exchanges, traffic control, public advertisements, and educational sectors. Further development to this project can be done by providing message storage facility by non-volatile memory i.e. EEPROM attached to the microcontroller for retrieval of old messages if required. It can also be expanded to a bigger LCD screen.

Anyone awake in the early 2000’s knows the familiar shape of those candy bar style mobile phones. In the Shenzhen phone markets we see tons of them. Literally, there are tons of these phone passing through the markets every day. Some are resold while others are disassembled for parts and recycled. This is where all those cheap Nokia 3310/5110 LCD shields come from. It’s great to see so much reuse and recycling.

Having all these cheap LCDs is nice, but most of the interesting and useful parts are wasted. We saw a fantastic opportunity to save a heap of phones from the recycling bin and save people a pocket full of money. We can make a positive impact on the environment if we reuse some of these phones that we are literally tripping over in the streets. Let’s make an Arduino to GSM network bridge for just a few dollars.

The GPS tracking device is composed of a microcontroller, GPS module, cell module, and batteries all housed in a 3D printed case. The microcontroller is programmed to communicate with both the cell module and GPS module. When the GPS module is not within a user-specified boundary, the device will send a text message alert. We made a device that can track people suffering from Alzheimer’s and Dementia could greatly benefit the quality of life of both that person suffering and the caretaker.

Recently we have learned how to interface GSM Module with Arduino and send/receive SMS using GSM module. Interfacing any device with a micro controller is the first step to building a useful system or project with that particular device. In this tutorial, we are going to build a very interesting project – a Fire Alarm System which will send SMS to a set of Mobile Numbers when fire occurs in a particular location. We have seen many typical Fire Alarm projects which will alert with a siren or an automatic shutdown mechanism. This fire alarm project make use of modern communication technologies to deal with emergencies.

Thanks to the enhanced functionality of the M95 FA module, this new version of the favorite GSM/GPRS module can be used for even more applications.

Quectel M95 communication module is already well-known among designers and we can say, that also very favorite. Its producer also knows this fact, that´s why Quectel decided to come to the market not with a new type, which might have other package, functionality,…. but a new version of M95, marked as M95FA. M95 FA maintains compatibility with the previous versions M95A (R1.0) and M95 EB, plus it naturally adds something new …Similarly like M95EB , even the „FA“ supports eCall and DSSS (Dual SIM single standby), but also supports digital audio, secure data transfer thanks to the SSL and other. M95 FA is based on the latest MTK chipset, ensuring long lifetime and availability. M95 gained various international certificates and meets all requirements in the GSM/GPRS bands.

To make the development easier, M95 FA is also available on the so called adaptor board – M95FA-TEA-03-STD,usable with the M10EVBKIT.
Detailed information can be found in the Quectel M95 flyer, Quectel 2014 catalogue and upon request we´ll send you complete detailed SW and HW documentation.

Arduino Tutorial: GSM/GPRS SHIELD (SIM900) SMS Send and Receive Tutorial on Arduino Uno

In this video we are going to see, how easy it is to send and receive SMS messages using the Arduino GSM/GPRS shield (with SIM900 chip) from Tinysine. The shield is capable of sending and receiving SMS messages as well as making and receiving phone calls. It can also connect to the Internet using the GPRS network. But we will take a look at this later on in another video.

In this video, we connect to the GSM network of COSMOTE in Greece and we send an SMS message to a cell phone. Then we reply to Arduino and read the message in the Serial Monitor in the computer.

Moreover, new UMTS/HSPA module Quectel UG95 is pin-compatible with GSM/GPRS module M95 thus offering extraordinarily simple way to migrate to 3G without a PCB redesign.

To have a possibility to choose a component on a given PCB place according to our wish is certainly advantageous. For example in audio equipment to use a simple operating amplifier (for less demanding applications) or in other case to use a pin-compatible high-end operating amplifier for more demanding applications (on the same PCB position). This compatibility is common in some fields, in other ones not that much …

In a segment of GSM/GPRS/UMTS modules is this compatibility a sort of an exception, so arrival of the new Quectel UG95 module on the market can be an interesting solution how to use the same design for smaller GSM/GPRS/EDGE connection (with the M95 module) and also for a substantially faster UMTS/HSPA connection with the UG95 module.

Do you use 2G module M95 and you wish for a higher transfer speed?

UG95 offer extraordinary possibility to design your device able to work with M95 or also with UG95 module. UG95 features more pins than M95 but their position is compatible, so at a PCB design it´s possible to place all pins on a PCB and their real use will depend on whether you´ll use M95 or UG95.In result it´s possible to assemble the same PCB with M95 or UG95 module according to given application requirements.

UG95 is based on a new Intel XMM6255 chipset. In general, UMTS/HSPA transfer offers not only a higher transfer speed of pictures and data but mainly higher reliability of connection even in hazard conditions. That can be very important for critical applications like telemetry, process control, security and similar. Because from a new module we usually expect enhanced functionality, even in this field the UG95 has what to offer, for example:

  • rich set of internet protocols – TCP/UDP/PPP/MMS*/SMTP*/FTP*/SSL* (*-in development)
  • standard industrial interfaces – USB 2.0/UART/I2C/PCM
  • high sensitivity and top-class audio algorithms, digital audio output (PCM)

New module is available in a form of the module itself – UG95EA-02-NCH-STD (suitable for a mass usage into a target appliance) and also in a form of a known „adapter board“ UG95-TE-A mainly intended for development using the UC20EVBKIT development kit.

Detailed information will provide you the UG95 presentation, UG95 specification and the document Quectel UG95&M95 compatible design.
