This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because of pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy

Features:

• Enhancement of GPS navigation e.g.time-to-first-fix improvement，dead-reckoning，slope detection
• Indoor navigation（floor detection，elevator detection）
• Outdoor navigation，leisure and sports applications
• Weather forecast Health care application（e.g. sirometry）
• Vertical velocity indication（e.g. risk/sink speed）
• Target devices Handsets such as mobile phones ,table PCs,GPS devices Navigation systems Portable health care devices Home weather stations Flying toys Watches
• PCB size (L*W): 1.52* 1.20cm / 0.60"*0.47"
