The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

and transmitter only compounds the issue and makes pressure sensor selection more difficult. Absolute and gauge pressure sensors represent two reliable pressure sensor types. Their fundamental ...

Freescale Semiconductor recently announced a new sensor–the MPL115A–that delivers absolute barometric-pressure values as 10-bit values via either an SPI or an I2C port. The small sensor operates over ...
