Our Work

SP Engineers is offering electronics hardware and software development services since 2014. Our development office is situated in Tallinn, Estonia. Our sales and support offices are in Tallinn, Estonia and London, UK.

Here are some projects we have been working with so far:

Electronics and IoT
IIRIS salt therapy device

Our customer is well-established professional halogenerator manufacturer. They needed a consumer device that can be used at homes. We designed electronics hardware and created embedded software for a device with touch screen user interface for salt therapy sessions at home. Device allows to select different levels of salt-aerosol concentration. It has various working modes.

Smart wild bird feeder

Battery powered wild bird feeder detects wild bird visits and takes high quality photos of birds. All photos are instantly published to web server over Wifi and can be seen via mobile apps. 

Cable connection tester

Industrial cable connection tester measures cable connections’ resistance and correctness. LED indicators allow easily to identify faulty connections.

Air pressure monitor for construction sites

All measurement data is sent to server-based application over GSM. Web-based user interface allows to get overview of device measurements. Device can be set up conveniently via mobile phone

Trackers for logistics sector

Compact trackers report their location on predefined time intervals over GSM network. Battery powered trackers have optimized power consumption logic, which allows them to have several weeks long lifetime. Web-based user interface allows to see trackers route on a map.

Mobile applications
Etnobird Smart Bird Feeder

Android and iOS mobile apps allow users to discover the world of wild garden birds. Mobile apps allow easily to track birds visiting user's smart bird feeder, get notifications, when seeds run out of feeder and get a deep insight of garden birds all over the world. We developed native mobile apps. created UX / UI design and server based backend for communication between smart bird feeder IoT device and mobile app. 

Numro educational app

Numro is Android app that allows parents to limit and control their children's smart device usage. Numro teaches children mathematics, tracks their sleep time, allows to see child's location and restricts their smart device usage. The application uses various device administration features, location services integrations and payment integrations. Also administration interface was created.

Documents scanning application

Our customer needed Android and iOS applications that would allow their employees and contractors to scan paper documents and upload them automatically to their cloud application.
We developed native applications with machine vision solution that allows real-time detection of documents from camera preview. Applications are able to work offline and publish all necessary data to cloud servers when-ever data connection becomes available again.

Emotional payment terminal

Our customer wanted to introduce an emotional touch for donation related payments. We created an Android application for taking payments and donations with various NFC payment terminals. Application allows to configure emotional visual and audio feedback to donator.

Asset management software

Android application for inventory management. NFC tag reading support allows to identify inventory easily by scanning it by phone and manage it accordingly.

Computer vision examples
Smart Bird Feeder

Machine vision is used to identify birds presence on the image and to identify birds species.

Measurement devices reading discovery

Machine vision is used for identifying measurement devices serial number, measurement reading and pointer position. Information is sent to server over mobile data.

Quality control

Machine vision is used to identify products with defects
