The Wireless Pressure Sensor & Breathing Rate Belt Pack combines a ±25kPa Differential Gas Pressure Sensor and a Breathing Rate belt to measure the expansion and contraction of a person’s chest while they breathe. When used as part of a data logging experiment students can begin to explore breathing patterns. Bluetooth | USB | Huge Battery Life | Independent Logging How does it work? Fitted inside the Belt is an inflatable air bladder, which is moulded to two rubber tubes. One of these tubes has a hand pump bulb that is used to inflate the air bladder, the other tube is used attached to the Differential Gas Pressure Sensor to monitor the change in pressure as the test subjects chest expands and contracts during breathing. Breathing patterns The Breathing belt is placed around the lower chest. The bladder in the belt is connected to a Pressure sensor and lightly pressurised. Changes in chest size due to breathing will create a change in pressure in the bladder, which in turn will be recorded by the sensor..

A new Smart Wireless range of science sensors that also function as data loggers in their own right using Bluetooth or USB connectivity. The new Bluetooth wireless sensors include a huge battery life and can be mixed & matched with existing SmartQ Sensors & Data Loggers! Works with SmartQ Our wireless sensors can be used in combination with other Smart Wireless Sensors or data loggers in the EasySense range, even more amazingly is that with the addition of a V-Hub sensor link you can continue to enjoy using your existing SmartQ sensors at the same time! The Power of Smart Wireless Our Smart Wireless sensors build on the design of our legendary intelligent SmartQ Sensors but adds Bluetooth wireless connectivity allowing users to connect to tablets and mobile phones using the new EasySense2 Software. Digital TechnologyOur digital sensor technology brings science to the classroom providing you with a robust, accurate and repeatable teaching experience from the start. Auto CalibrationWe have taken the hassle out of setting up your experiments with our pre-calibrated, auto identify sensor technology, every sensor is ready to use out of the box. USB ChargingOur Smart Wireless sensors are powered by an internal battery and can be charged via a standard USB charger. Designed for MobileWith the included Bluetooth connectivity the new Smart Wireless Sensors can connect to Tablets, Mobile Phones, Laptops and Desktop Computers Smart Connectivity Not only do the Smart Wireless Sensors connect to multiple tablets and mobile devices via Bluetooth but they can also connect directly to a desktop computer and be used just like a traditional data logger whilst offering faster data transfer rates.
