Why you should choose Versatronics for your project

With over 40 years in the electronic industry and experience in analogue, digital, DC, RF, Arduino and Pic controller and software design, we can probably do what you need. You will get personalized and understanding treatment with the utmost confidentiality. We are able to design down to component level - a skill that is getting harder and harder to find these days. We make prototypes, PC boards, proof of concepts and one-off products.

We also provide website and software development services, including IoT solutions. We can build custom devices that receive sensor data and communicate that data back to the cloud which can be monitored via the Internet.

Latest Project

Did you want something measured or monitored, and the results uploaded to a remote web page, where it can be seen from anywhere in the world? Typical applications might be monitoring a rainwater tank level at your holiday home at the coast, while you are working abroad. The ESP8266 Wi Fi module makes this easy, and we have implemented many such systems using Arduino processors. Modules can also talk to each other or even act as web servers in the local network.
The module on the right is a Arduino Atmega328 with a built in plug-in ESP8266 module. I also have a similar one with a plug-in sim800 cell phone module which can send you sms's about your data. The Arduino board has an additional 5 analogue and 3 digital I/O for connections to sensors. It only requires an external 12V PSU.

Projects in development

Projects in the design stage include:

  • A fall alarm for old persons, uses a wrist worn 'panic button' which connects to a cell phone module and dials 5 designated responders and sends an SMS to say the person has fallen. The responder can sms back making the unit sound a loud beep to give the victim confidence that help is on the way.
  • A sophisticated quiz game which includes 4 contestant stations and a quiz master station. Once the contestant hits the button the others are locked out, but 2nd 3rd and 4th places are saved so if the first responder is wrong, the action moves to responder 2 etc. A timer is included and each contestant has a large display showing their accumulated score.
  • A car burglar alarm that sends you an sms, and you can sms back to disable the ignition.
  • A water flow-rate and temperature sensor to enable detection of potential for Legionnaires bacteria to grow in hotel water pipes
