Navigating Building Automation: Our Expertise

Building access control

RFID is a contactless system using radio waves to track and identify tags. It consists of tags and readers, with tags transmitting data when exposed to readers' radio waves.

There are two main tag types: low frequency (125 kHz) for building access control systems and high frequency (13.56 MHz) for contactless bank cards and high-security systems.

NFC is a high-frequency RFID-based protocol, and MIFARE is another notable transmission protocol.



Passive tags: building access cards, key card entry systems for building, key fobs, bracelets, coins, and stickers.
Active tags: specialised devices, smartphones with peer-to-peer mode (Android, iOS).
Readers: specialised devices, smartphones (Android, iOS).

Water leak detection and drip irrigation systems

Leak Detection Systems (LDS) aid in pinpointing pipeline leaks, offering alerts and data for efficient decision-making, ultimately enhancing pipeline reliability. Leakage controllers are required in pumping stations and boiler rooms.

Drip irrigation systems deliver water directly to crop roots, optimising efficiency and minimising waste. By utilising networks of pipes, hoses, and emitters, drip irrigation proves advantageous for high-value crops. This method necessitates more frequent irrigation compared to sprinkler systems.

These systems can be linked to smartphones through cloud connectivity, enabling control and monitoring.
