ANTplus (ANT+) radio in smart phone will control machines

Last week I proposed to one of my project customers to use an ANTplus (ANT+) powered smart phone as remote control for their machines. As we all know, there is no Bluetooth LE available. The other reason was that the costs for qualification with ANTplus are much lower than with Bluetooth LE. Even if we […]

ANT the coin cell battery powered WSN (wireless sensor network) – Free webinar

ANT is a low-power wireless networking protocol. It has the same audience like Bluetooth Low Energy. In contrast to Bluetooth LE the ANT protocol allows full mesh network topology. Furtermore it is already widespread in sports and healthcare. The ANT alliance has more than 300 members (e.g. Adidas, Garmin or Timex). The member no. 300 was the manufacturer of phones, Sony Ericsson.

MP45DT01: Digital microphone for people tracker, antitheft systems and wireless video cameras

Digital microphone to deliver crystal-clear audio and to eliminate the “GSM noise” in your M2M application

The MP45DT01 MEMS, digital-output microphone enables advancements in sound quality by providing omni-directional sensitivity to detect and filter out background noise. Sound quality can be further improved by incorporating multiple microphones in one device.

Cellular antenna working inside all-metal case

Capacitive-feed antenna that can be enclosed in an all-metal mobile handset case People that know and follow me a longer period already note that I am reading and collecting anything about embedded cellular antennas that looks unique.  My hard disk is full with files about special small embedded antennas. Today I make a text public […]

The evaluation board „smart-GSM/PLC“ makes it possible The GSM-PLC board is designed to realize development from e.g.: Remote Control boxes with digital I/O‘s Remote Control boxes with analog inputs Gate opener via call by mobile phone Telemetry boxes Data logging Counter monitoring GPRS / GSM burglar alarm and much more On its I2C bus you […]

M2M module: Embedded Linux, ARM9, GPRS module, USB and further Interfaces

Today I would like to show and to talk about a new Linux based application for wireless M2M. The PCB is already in use in several projects. Based on its enclosure it can be used as a final product for end users. It supports a lot of interfaces like SD card / MMC card, GPIO Pins , AD / DA converter, UARTs, USB Device, USB Host, I2C, SPI and JTAG. At GPIO you will find PMW (Pulse Wide Modulation), counters and other intelligent channels.
