VCP-BAR20
Product Description
USB Precision barometer – with VCP mode
This USB-connected barometer allows for precise measurement of atmospheric pressure (1 kPa to 120 kPa) and altitude. Thanks to the use of a high-resolution ADC 24 bit, very small changes in atmospheric pressure can be sensed and sent to a computer over USB. If used to compute altitude, variations as small as 10 cm can be detected. Designed as a compact USB-Key form factor for easy integration even in space-constrained applications.
