2.10 Calibration

Select the Calibration tab to view your calibration data from the weather station.

Calibration of most parameters is not required, except for Relative Pressure, which must be calibrated

to sea-level to account for altitude effects. For more information on sea-level pressure calibration,

please reference note (3) below.

2.10.1 Relative Barometric Pressure Calibration Example

The following is an example of calibrating the relative pressure. Your results will vary.

1. The local relative pressure from TV, the newspaper, or the internet for the official station in

your area is 30.12 inHg.

2. From the Live Data panel, your absolute pressure (measured, and not corrected to sea-level)

reads 28.90 inHg.

3. Reference Figure 7. Enter the following offset in the Calibration panel for Relative Pressure

Offset:

Relative Pressure Offset = 30.12 – 28.90 = 1.22

(1) Temperature errors can occur when a sensor is placed too close to a heat source (such as a

building structure, the ground, or trees).

To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Bi-metal

(dial) and digital thermometers (from other weather stations) are not a good source and have

their own margin of error. Using a local weather station in your area is also a poor source due

to changes in location, timing (airport weather stations are only updated once per hour) and

possible calibration errors (many official weather stations are not properly installed and

calibrated).

Place the sensor in a shaded, controlled environment next to the fluid thermometer, and allow

the sensor to stabilize for 48 hours. Compare this temperature to the fluid thermometer and

adjust the OBSERVERIP2.0 receiver to match the fluid thermometer.

(2) Humidity is a difficult parameter to measure electronically and drifts over time due to

contamination. In addition, location has an adverse effect on humidity readings (installation

over dirt vs. lawn for example).

Official stations recalibrate or replace humidity sensors on a yearly basis. Due to

manufacturing tolerances, the humidity is accurate to ± 5%. To improve this accuracy, the

indoor and outdoor humidity can be calibrated using an accurate source, such as a sling

psychrometer.

(3) The OBSERVERIP2.0 receiver displays two different pressures: absolute (measured) and

relative (corrected too sea-level).

To compare pressure conditions from one location to another, meteorologists correct pressure

to sea-level conditions. 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 absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305

m), but the relative pressure is 30.00 inHg (1016 mb).

The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average sea-level

pressure around the world. Relative pressure measurements greater than 29.92 inHg (1013

mb) are considered high pressure and relative pressure measurements less than 29.92 inHg are

considered low pressure.

To determine the relative pressure for your location, locate an official reporting station near

you (the internet is the best source for real time barometer conditions, such as Weather.com or

Wunderground.com), and set your weather station to match the official reporting station.

(4) Only use this if you improperly installed the weather station sensor array and did not point the

direction reference to true north.

(5) The default conversion factor based on the wavelength for bright sunlight is 126.7 lux / w/m2.

This variable can be adjusted by photovoltaic experts based on the light wavelength of

interest, but for most weather station owners, is accurate for typical applications, such as

calculating evapotranspiration and solar panel efficiency.

(6) Wind speed is the most sensitive to installation constraints. The rule of thumb for properly

installing a wind speed sensor is 4 x the distance of the tallest obstruction. For example, if

your house is 20’ tall and you mount the sensor on a 5’ pole:

Distance = 4 x (20 – 5)’ = 60’.

Many installations are not perfect and installing the weather station on a roof can be difficult.

Thus, you can calibrate for this error with a wind speed multiplier.

In addition to the installation challenges, wind cup bearings (moving parts) wear over time.

Without a calibrated source, wind speed can be difficult to measure. We recommend using a

calibrated wind meter (available from Ambient Weather) and a constant speed, high speed fan.

(7) The rain collector is calibrated at the factory based on the funnel diameter. The bucket tips

every 0.01” of rain (referred to as resolution). The accumulated rainfall can be compared to a

sight glass rain gauge with an aperture of at least 4”. The following is a link to an accurate

sight glass rain gauge:

http://www.ambientweather.com/stprraga.html

Make sure you periodically clean the rain gauge funnel.

Note: The purpose of calibration is to fine tune or correct for any sensor error associated with the

devices margin of error. Errors can occur due to electronic variation (example, the temperature sensor

is a resistive thermal device or RTD, the humidity sensor is a capacitance device), mechanical

variation, or degradation (wearing of moving parts, contamination of sensors).

Calibration is only useful if you have a known calibrated source, you can compare it against, and is

optional. This section discusses practices, procedures, and sources for sensor calibration to reduce

manufacturing and degradation errors. Do not compare your readings obtained from sources such as

the internet, radio, television, or newspapers. The purpose of your weather station is to measure

conditions of your surroundings, which vary significantly from location to location.

2.11 Adding Additional Sensors

The OBSERVERIP2.0 module supports up to 8 additional thermos-hygrometer sensors (Model

WH31E, WH31P, WH31PF). Place the sensors in and around your home and monitor on

AmbientWeather.net.

The data is automatically passed from the OBSERVERIP2.0 module to AmbientWeather.net based on

the channel number.
