61302V Barometric Pressure Sensor
1.
INTRODUCTION
MODEL 61302V Barometric Pressure Sensor is a versatile
electronic barometer featuring high accuracy, low power, wide
operating temperature range, and RS-232 serial data I/O or a
calibrated voltage output.
Low power consumption and wide temperature range make the
61302V ideal for remote applications using battery or solar power.
An accuracy of ±0.3 hPa rms is maintained over the entire
specified operating pressure and temperature range. Full scale
voltage output (2.5V or 5V) may be set to span any portion of the
500 to 1100 hPa operating range. RS-232 serial I/O options
include continuous or polled ASCII text output or NMEA marine
output. The sensor is supplied with the following standard
configuration:
•
RS232 serial output (TTL levels)
•
Polled mode, 9600 baud ( 8 bit/1 stop bit/no parity)
•
Measurement range = 500 to 1100 hPa (10 samples
averaged, Output when polled)
