PHD Devices designs and builds IoT hardware and software — from your first prototype through to full-scale production. Then PHD Cloud, our device management platform, keeps every unit online, monitored and up to date.
No handoffs between a hardware shop, a firmware contractor and a separate platform vendor. We carry your device through every stage, under one roof.
We take your idea from sketch to a working proof of concept — schematics, PCB layout and a functional first build.
Hardware, firmware, mobile and cloud software developed together, so every layer of the product actually fits.
Design-for-manufacture, sourcing and production scale-up — from your first ten units to your first ten thousand.
Every device connects to PHD Cloud for fleet health, remote updates and alerts — support doesn't stop at shipping.
Clients trust us to build their prototypes — and rely on us to take those same devices into production and ongoing support. With experience spanning aerospace-grade data acquisition systems for rocket telemetry, secure barcode technologies for intelligence workflows, and specialised interface hardware across multiple industries, our team brings enterprise-grade engineering rigor to every project.
Multilayer circuit boards designed in Altium Designer by experienced electronic engineers.
Product housings and mechanical assemblies engineered for real-world environments.
Low-power, reliable firmware for microcontrollers, FPGAs and connectivity modules.
Mobile apps, web dashboards and cloud services that turn raw device data into something usable.
Design-for-manufacture, sourcing and assembly partnerships to take a prototype to volume.
Every unit verified functioning, with support through compliance and certification.
Every device we build for you connects into PHD Cloud — one dashboard for fleet health, remote updates, alerts and usage analytics.
We used our own process to design, build and bring our first product to market.
An automatic, volume-based IoT-enabled fuel additive dosing system — sensing, dosing and remote monitoring, designed and built end-to-end by PHD Devices.
±0.001% dosing ratio precision
Energy Tech Review Magazine named TankDose the Top Automatic Volume-Based Dosing Device Solution in APAC for 2026 — recognising its patented approach of measuring actual tank volume change, rather than estimating from flow, to hold dosing accuracy to ±0.001%.
"TankDose was purpose-built to eliminate manual dosing, remove operator error, and finally give the fuel-additive industry a technology that matches the precision of modern additive chemistry."— Pauline Horan Dunn, Founder & Managing Director
