Sequoia Technology Group is a leading designer and provider of 'real-life' electronic solutions serving the M2M-wireless, touchscreen kiosk, remote monitoring, SMSprinter and antenna markets.
'Focused on Design' has been the theme for Sequoia since its inception in 1986 and continuingly so. We focus on designing all aspects of hardware and software for our products and custom projects for our customers using our in-house designers. We design and manufacture in-house and with selected partners to deliver the end designs, products and overall solutions.
Sequoia is well known as the leading wireless product supplier from GPRS, GPS, Zigbee, 802.15.4 modules, to custom software to run the products. Sequoia has for some years now designed, developed and manufactured many of its own wireless products. These are used as end equipment for some customers or as OEM products for inclusion into our customers' systems. GPRS and 3G modem terminals are examples with Ethernet and micro controlled versions shortly to be available. We even use our terminals in our own remote monitoring products within our Sensormetrix division. Cellular Signal strength testers for 2G and 3G networks are also popular Sequoia products.
Many companies and customers use Sequoia products for their cellular, GPS and antenna designs where we advise which products will perform the desired functionality, we help with PCB layout (or do it), supply relevant Sequoia customised software and antenna designs. In some cases we do the complete process including volume manufacture. Through the many years of experience in doing this customers know that Sequoia wireless designs work.
Other divisions:


Designers and manufacturers of 'cutting-edge' look touch-screen kiosks employing the latest computing technology. Our designs are unique in the kiosk world for their great looks, small size, new computing technology and low price. They are designed by us to be easy to use with our intuitive software. Our touch screen kiosks are used by many local councils, the NHS, Mental Health care organizations and the prison service, all providing information and support for parents, carers, local residents, tenants and others.
The new range of Nixi micro kiosk, Eidos DDA compliant kiosk and the ultra-cool Okul kiosk represents the latest design thinking for the retail market and have been well received by all that view the range and its design and capability.
Our customised software designs complete the total kiosk solution when used with our small footprint touchscreen Kiosks. All our products are designed in-house and use industrial grade electronics for very long life and are uniquely brand-able.


One of the widest range of antennas for M2M, wifi, GSM, GPS and most other wireless systems. Every wireless product needs an antenna. Just about every electronic product or system is going wireless. Siretta caters for all antenna requirements - standard or custom. Siretta products are designed and built for a specific performance as specified by ourselves or our customers. We performance-match our antennas to our customers' wireless systems.
Our antennas and matching RF cables are manufactured by our selected manufacturing partners in Eastern Europe or the Far East. This ensures a quality construction at a competitive price. Most antenna systems need RF cables internally or for connecting the antenna to the equipment - Siretta manufactures any permutation of cable with any length and connector or termination. Siretta antennas and cables are available from many distributors in Europe.


Sensormetrix is the definitive business for remote monitoring and control products and systems. Remote monitoring of temperature, humidity or other sense-able parameter - over the internet or GSM network. We offer the ability to data-log sensed parameters and to generate alarm emails or SMS texts for out-of-set-parameter situations.
Sensormetrix' systems makes the desirable possible at a sensible price - and with simplicity. Whether it be a range of freezers and refrigerators needing monitoring or a second home in a different country or a server room that needs careful monitoring remotely -Sensormetrix' solutions provide the reliable answer.
Many of our solutions are designed and manufactured in-house, including the software, using our considerable wireless expertise within the group. Remote control is also a growing facet of Sensormetrix' product range where end equipment needs to be re-booted or something switched on or off from a remote location in response to an email / SMS signal equally received remotely. Sensormetrix cellular wireless and internet expertise makes this remote monitoring and control look easy, reliable and most importantly, usable by anyone for many and varied situations.


Video products in the HDTV market is also a speciality of Sequoia where we are one of the small number of centres of detail knowledge and experience in HDMI techniques in Europe. Sequoia now has a growing competence and product range in AV products. This includes HDMI signal distributors, multiplexers, media players and long distance transmission of HDMI signals over fibre cables. Sequoia has the experience, product range and technical competence to specify, supply and install complete AV systems


The Sequoia sensor division concentrates on providing more unusual approaches to sensor technology and the know-how of its application. Heat flux sensors have been a Sequoia speciality for a number of years along with the intrinsically safe fabry-Perrot principle fibre-optic sensing system. Sequoia is now also producing combined temperature and humidity sensors for use in OEM equipment and terminated for USB, RS232 and 1-wire systems.
The sensor division also produces linear amplifiers and dataloggers for use with any small signal sensor that requires precision amplification and datalogging. Sequoia Sensors has an ambitious product plan to create a range of sensing products (precision sensing components and relevant interface electronics) to fit easily into OEM system products and with a defined accuracy and price point.
