The First Webcam Watched a Coffee Pot
Before webcams watched newsrooms, doorbells and factory floors, the very first one watched a coffee pot. In 1991, a group of computer scientists at the University of Cambridge pointed a camera at a humble filter coffee machine and streamed its image across their building's network. Their motivation was gloriously ordinary: they were tired of walking to an empty pot.

Before webcams watched newsrooms, doorbells and factory floors, the very first one watched a coffee pot. In 1991, a group of computer scientists at the University of Cambridge pointed a camera at a humble filter coffee machine and streamed its image across their building's network. Their motivation was gloriously ordinary: they were tired of walking to an empty pot. That small act of laziness produced the world's first webcam and, in hindsight, one of the clearest early examples of what we now call the Internet of Things.
The Trojan Room coffee pot
The machine lived in a corridor known as the Trojan Room, in the Computer Laboratory. Researchers scattered across other floors and offices shared that single pot, and there was nothing more deflating than climbing the stairs only to find it drained. So Quentin Stafford-Fraser and Paul Jardetzky rigged up a camera aimed at the pot, connected it to a spare video capture board, and wrote a small program that grabbed a fresh frame a few times a minute.
That program, nicknamed XCoffee, let anyone on the local network open a tiny window on their workstation showing a live, grayscale image of the coffee level. No more wasted trips. It was crude - a postage-stamp picture updated slowly - but it worked, and it quietly solved a real problem for the people who used it every day.
From local network to the whole world
For its first two years the coffee cam was a private convenience, visible only inside the lab. Then in November 1993, as the World Wide Web was beginning to spread, colleagues Daniel Gordon and Martyn Johnson connected the feed to the web itself. Suddenly anyone on the planet with a browser could check whether a coffee pot in Cambridge was full.
It became a minor internet celebrity. People visited from all over the world just to watch coffee brew thousands of miles away, and the Trojan Room pot is now widely credited as the first webcam ever put online. The camera was finally switched off in August 2001, and the original coffee machine was auctioned - fittingly, over the internet.
Why a coffee pot is really an IoT story
Strip away the novelty and the coffee cam is a textbook connected device. It had a sensor (the camera) observing the state of a physical thing (the coffee level), a network to carry that state somewhere useful, and a remote interface where a human could act on the information. That exact loop - sense, transmit, decide - is the beating heart of every modern IoT system, whether it is a soil-moisture probe in a rice field, a cold-chain temperature logger, or a fleet of smart electricity meters.
The coffee pot also captured something that engineers still design around today: the value of an IoT device is rarely the raw data. It is the wasted effort it removes. Nobody cared about the pixels; they cared about not climbing the stairs for nothing. Good embedded systems work the same way. The sensor and firmware are only interesting because they let a person, or another machine, skip a costly action.
The same idea, built for real products
Three decades later, the tools are far more capable but the pattern is unchanged. A microcontroller like an ESP32 now does what a rack of 1991 equipment could not, streaming sensor data over Wi-Fi to a cloud dashboard for a few dollars in parts. Here in the Philippines, that shift matters. Local startups, agricultural cooperatives and student thesis teams can prototype genuinely useful connected products - remote water-level monitors, energy meters, equipment trackers - without a Cambridge-sized budget.
That is exactly the work we do at Fluidwire. We take an idea for a connected product and carry it from silicon to cloud: the board and firmware, the network layer, and the web services and dashboards where the data finally becomes useful. Whether you are a business digitising a physical process or a student turning a thesis concept into a working prototype, the path is the same one those Cambridge researchers stumbled onto - put a sensor on the thing that matters, move its state to where decisions happen, and save someone a pointless trip.
