1000 Series Barometric Pressure Sensor Wiring and Installation

Barometric Pressure Sensor needs to be mounted outside, to measure pressure externally from Greenhouse.

You would mount the sensor at one of the Analog outputs (1 thru 5) and you would map as an analog sensor.

Since the sensor is semi-sealed, minimum maintenance is required:

Visually inspect the cable connection to ensure it is clean and dry.

A barometer, along with a rain gauge and wind direction sensor, is an excellent way to predict storm activity. You need to check weather history to find out the average barometric pressure for your reading. Is it 999 hPa or 61 mb?

Example:  If the pressure readings drop and the wind velocity is up, you're in for a thunderstorm

Just make sure you check both surface and sea level readings, since barometric pressure levels can vary depending on whether you're on a mountainside or on solid ground.

 Calibrating the Barometric Pressure. To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level. Because the air pressure decreases as you rise in altitude, the sea-level corrected pressure (the pressure your location would be at if located at sea-level) is generally higher than your measured pressure. Thus, your pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m), but the corrected pressure is 30.00 inHg (1016 mb). The standard sea-level pressure is 29.92 in Hg (1013 mb).
