Formosa FBM320

The FBM320 is a new generation of high resolution digital barometer. It is a digital pressure and temperature sensor which consists of a MEMS piezoresistive pressure sensor and a signal conditioning ASIC. It is low power and supply voltage designed and suitable for portable devices or battery-supplied ones. More information at Formosa dedicated page.
