Features: brand new and high quality This patented single-element transducer combines advanced micromachining technology, thin-film metallization and bipolar processing technology. The MPXV7002 series piezoresistive transducer in the small outline package (SOP) is a state-of-the-art monolithic silicon pressure sensor designed for a wide range of applications. The MPXV7002 is designed to measure positive and negative pressure. Particularly those employing a microcontroller or microprocessor with A/D inputs. What's more, with an offset specifically at 2.5V instead of the conventional 0V, this new series allows to measure pressure up to 7kPa through each port for pressure sensing but also for vacuum sensing (refer to the transfer function in the data sheet for more detailed information). Specifications: Material: Metal+ABS Size: 1.1x0.86x0.47 in Package Includes: 1 x Breakout Pressure Sensor 1 x Connecting Wire note: Please allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid.
