Description
Take espresso brewing to a scientific level with the BOOKOO Wireless Sensor. The Bookoo Espresso Monitor is not just an ordinary pressure gauge, it is a digital sensor that transforms your espresso machine into a smart device.
Instead of watching an oscillating analog needle, you get a precise digital pressure profile in real time, displayed directly on your smartphone or tablet. This high-tech accessory measures water pressure at the group head during extraction and visualizes the data instantly in the BOOKOO app.
Main functions
- Real-time monitoring - Forget about guessing. A sensor measures the water pressure directly in the coffee machine head throughout the extraction process. The data is transmitted instantly and without delay via Bluetooth to your app, so you have full control over the preparation process.
- Advanced Analysis and Flow Profiling - Turn data into better coffee. With the support of the BOOKOO APP or Beanconqueror, you can visualize pressure curves, save successful recipes and compare different extraction profiles for perfect repeatability.
- Wide compatibility and easy assembly - Bookoo is compatible with most premium coffee machines:
- G1/8 thread : Direct compatibility (ideal for Flair 58).
- M6 adapter included : Allows easy installation on machines with E61 head (e.g. Lelit, Rocket Coffee, Profitec, ECM and others).
- Scale integration – the ability to connect to Bluetooth scales such as BOOKOO Themis Mini Coffee Scale With Digital Timer And Flow and others (Acaia, Felicita) to obtain more comprehensive data. In one graph you will see the interplay of pressure, flow rate and resulting weight, which will give you a comprehensive view of the extraction dynamics.
- Wireless freedom and endurance - No cables to clutter up the barista counter. The device has an integrated battery with a long battery life (tens of hours of active use), which you can conveniently charge via USB-C. In standby mode, the sensor has minimal consumption, so it is always ready for the next cup.

Want to see both pressure and water flow in one graph? Connect the sensor to your BOOKOO digital scale and gain absolute control over every parameter of your espresso.
