New GSM/GPRS/GPS/GNSS modules Quectel offer also special functions, able to make your product exquisite.

Development in the field of communication modules is fast and there are still more segments for their applications. That´s why company Quectel always comes with novelties or at least with enhanced versions of existing modules. This is also the case of two novelties M95EB and UC15.

Module M95 is certainly familiar to you from several our articles like for example Even the Vodafone confirmed quality and reliability of Quectel M95 GSM module. M95 belongs to a TOP in the segment and recently we announced you an eCall support. Meanwhile, this version came to a mass production and we can easily differentiate it by the „EB“ suffix. New version M95EB also supports Dual SIM function (DSSS), what makes it extra reliable even for emergency systems and similar applications. A previous M95 as well as new M95EB are compatible and they will be on the market in parallel, that´s why company Quectel recommends to use the new version (EB) only for applications where you plan to use these new functions.The second novelty is the UC15 module (UMTS/ HSDPA), which is similar to UC15 in many respects, but it´s smaller (29x29x2.5mm) and it has only 66 pins. The main difference is that UC15 doesn´t support GPS/ GNSS and it´s also somewhat slower (upload). UC15 is cheaper than UC20 and in many applications it can represent a very interesting alternative for a very attractive price.

A comprehensive description and comparison of Quectel modules can be found in the Quectel brochure as well as in the datasheets in particular types.

With modules Quectel UC15 and M95EB you’ ll gain Dual SIM, eCall, HSDPA and other functions - [Link]

The Arduino compatible board to take your projects beyond your home and garden. Anywhere your imagination takes you.

Prototyping should be rapid. Putting projects together should be as easy as clicking together lego-like building blocks. SODAQ makes it so. SODAQ is a multi-feature microprocessor board that lets you connect sensors and devices to the internet, quickly and with no fuss. It’s designed for connecting things efficiently, running off-grid with built-in, ready-to-go solar power:

Getting data off a device is only half the story – it needs to go somewhere. We designed the SODAQ system to be able to communicate from anywhere, with a GPRS module and all the control code for it included from the start.

It takes the Arduino prototyping concept, makes it simpler, and extends it. No breadboarding or soldering required, but with plenty of memory, sockets, solar panel and battery control, and extra features, all on one board.

The board has built in sockets for Grove modules; a realtime clock; extended flash memory; USB on-board; and the Bee socket can take any WiFi/RF/XBee or other compatible plugin for communications instead of our GPRS module.

It’s small but packed with features. The GSM alarm we present today, sports a PIR motion sensor, can be battery operated and it’s capable to communicate via GSM. It can transmit alarm conditions and receive commands from remote. It’s also capable to indicate problems such as is insufficient voltage supply or tampering.

It’s not so conventional for antitheft system: to integrate a movement sensor, a PIR motion sensor and a temperature probe in a single appliance: all this accompanied by an SMS sending GSM / GPRS module. This circuit was born as a very versatile, ready to use, built-in alarm system: no installation is required, you can just drop it and it’s ready to work. It’s not by chance that is designed to be battery operated: it also features a battery state control to check the power.

AT command tester is a free online software tool that is used to test AT commands and other functionalities of GSM modems. The friendly user interface allows developers to,

  • Configure and connect to modem ports
  • Send single or batch of AT commands
  • Perform modem diagnostics
  • Establish 3G or GPRS call
  • Collect and save modem logs

Port Configuration

AT Command Tester uses Java-based serial drivers to interface to the modem. The ‘Find Ports’ button will automatically find all ports available in the system. The user can connect the appropriate modem port with the desired port speed.

Command mode

After connecting successfully to the modem, users can send single AT commands under ‘Command Mode’ tab. The drop down provides list provide list of AT commands with description and examples. The users can modify or enter their own AT command in the text box. Read the rest of this entry »

This is a shield for Arduino designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS. This new version has several new hardware features, that allow maximum customization and provide many configurations. With a microphone and a headset with a 3.5 mm jack (just the standard headphones for computers), you can make a voice call from Arduino!!

The device is based on a GSM/GPRS module with included GPS. Its main function is to detect and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. Its small dimensions are due to the use, for the first time, of a GSM/GPRS module integrating the GPS receiver. That is the SIM908 a recent product by SIMCOM.

The circuit of the localizer is build around two boards, one with the SIM908 on board and the second one including the microcontroller and the battery charger for the lithium battery. To get the GPS working will be necessary to complete the localizer circuit with an appropriate antenna.

Libelium has introduced their 3G/GPRS shield for Arduino (3G + GPS). It enables connectivity to high speed WCDMA and HSPA cellular networks, and includes GPS. [via]

 The GPS module also makes it possible to perform geolocation services even in indoors as it can work in A-GPS and S-GPS modes, so the location given by the GPS through NMEA sentences is completed with the cell information provided by both the 3G module and external Internet Geoposition Servers which helps you to get the most accurate location in each case.

A modem GSM & GPRS with SIM900 or SIM908 module. Allows you to create data connections on the GSM network through a standard USB interface. The cellular modems, particularly USB-stick ones, are now at very affordable prices, however they’re limited: they are explicitly designed for Internet connections, so you cannot use it as a normal modem and so implement, for example, a point to point data communications with them. The GSM modems that allow this are quite rare, and so we create and offer you one: it is a device for PC with an USB interface with “voice” functions: there is a jack for a speaker and one for microphone.

Quectel launched on the market another quad-band GSM/GPRS module – M95. In an easily solderable LLC package offers M95 a reliable solution in a very compact size.

Besides all features, which can be required from a modern GSM/GPRS module, provides M95 high performance at an extremely low power consumption. M95 has a built-in class AB audio amplifier, which further simplifies hardware design of a target device. The module is able to operate reliably at an extended temperature range from -40 to +85 °C. With embedded powerful internet service protocols, represents M95 a complete solution usable as an embedded module in many M2M applications. An advantage of the M95 module is also a very competitive price. For support of development is the M95 module also available on an adaptor board M95TE-A, which can be inserted into the development kit M10EVB-KIT.

Detailed information will provide you the M95 Hardware Design, M95 AT Commands set and the M95 datasheet. M95, as well as M95 on an adaptor board, are available from our stock. Guide price of the M95 module is 11-15 Eur. We´ll let you know the exact price for your project upon request.

Quectel M95 will provide you SMS, voice, data and a simple usage - [Link]

Autonomous live tracking weather station. It takes (analog/digital) measurements and sends them to a web server over GPRS. Adding a battery and a solar station you can make it fully autonomous. It supports up to 3 Analog or Digital inputs. The main brain is the PIC 16F877A which also drives the SIM900/300 GSM module which is placed in the back of the PCB.
The main purpose of this project is to take wind flow measurements of different locations and store them in a database remotely. By this you know if the locations are appropriate for future installation of wind generators.

The data send from GSM to Web server with GET requests which isn’t the safest and best way but its an easy way to make it work. The example code you can find at the github is a very simple example and has no security responsibility.
