Introduction

The Wireless Weather Sensor with GPS is a versatile instrument with multiple sensors, including a Global Positioning System (GPS) module. The sensor is durable and weather-resistant, and it can connect wirelessly via Bluetooth to a computing device such as a tablet or computer using PASCO Capstone or SPARKvue. The software supports data logging when the instrument is not connected to a computing device. The Wireless Weather Sensor has a rechargeable battery pack. The sensor measures wind speed, barometric pressure, relative humidity, ambient temperature, illuminance, UV index, solar irradiance, solar PAR, magnetic heading, and wind direction. The GPS module reports latitude, longitude, altitude, horizontal velocity, and satellite count. The software can calculate dew point, true heading, wind chill, absolute humidity, and heat stress index.

Measurement tips

Equilibration time
After a rapid change in temperature or humidity, the sensor may take several seconds to come to equilibrium with the environment. Observe the measurements and wait for them to stabilize.
Alignment with wind
Hold the sensor so that wind blows straight into the front of the anemometer.
Shade
The sensor, especially the temperature and humidity transducers, must be out of direct sunlight to make accurate measurements.
Moisture
Protect the sensor from liquid water. The sensor is rugged and weather-resistant, but not waterproof. Exposure to liquid water is likely to cause inaccuracies in collected data.
Weather Vane Accessory
When measuring weather conditions like wind speed and direction, consider using the PS-3553 Weather Vane Accessory to maximize accuracy of the data collected.
Wireless Weather Sensor
measurements
Primary measurements
The Wireless Weather Sensor’s primary measurements are Wind Speed, Temperature, Relative Humidity, and Barometric Pressure.
Wind Speed
The sensor determines Wind Speed from the rate of rotation of the anemometer (wind turbine). It assumes that air is flowing directly into the turbine. Wind speed must be at least 0.5 m/s to be measured accurately. Wind Speed can be reported in units of m/s, cm/s, mm/min, km/h, mph (miles per hour), knots, or ft/s
(feet per second).
CAUTION:
Do not try to measure high-speed wind, such as from leaf-blowers or severe storms.
Temperature
Temperature is measured by the thermistor temperature transducer. To work accurately, the transducer must be in shade. Temperature can be reported in °F, °C, or K.
Relative Humidity
Relative Humidity is measured by the humidity transducer. To work accurately, the transducer must be in shade and at air temperature. Relative Humidity is reported as a percentage representing the ratio of the partial pressure of water vapor to the saturated vapor pressure.
Barometric Pressure
Barometric Pressure is measured by a pressure transducer in the sensor’s “window”. The reported Barometric Pressure is the actual air pressure, not the sea-level corrected pressure. Barometric Pressure can be reported in units of kPa (default), psi, N/m2, atm, torr, hPa, inHg, mmHg, mbar, Pa, or inH2O.
Secondary measurements
Each secondary measurement is a calculation based on one or more of the primary measurements.
Absolute Humidity
Absolute Humidity (or water vapor density) is a measure of the mass of water vapor present in a given volume. It is reported in units of g/m3. The sensor calculates Absolute Humidity with the following formula:where RH is the Relative Humidity (as a percentage) and T is Temperature in °C.
Dew Point
Dew Point is the temperature to which air must be cooled at constant pressure for water vapor to condense. Dew Point is reported as a temperature in °C or °F. The sensor calculates Dew Point (in °C) with the formula:In this formula, RH is the Relative Humidity (as a percentage), T is Temperature in °C, and SatVP is the saturation water vapor pressure, given by:Wind Chill
Wind Chill (or Wind Chill Index) indicates a combined effect of temperature and wind speed. It is reported as an apparent temperature in °F or °C. The sensor calculates Wind Chill (in °F) using the formula:where T is air temperature (in °F) and v is wind speed (in mph). Wind Chill is defined for temperatures at or below 50 °F and wind speed above 3 miles per hour; outside of those limits, the sensor reports a value equal to Temperature.
Heat Stress Index (Humidex)
Heat Stress Index (or Humidex) indicates a combined effect of temperature and humidity. It is reported as an apparent temperature in °F or °C. The sensor calculates Humidex (in °C) using the formula:where T is the ambient air temperature in °C and e is the water vapor pressure in kPa.
Sea-level corrected pressure
A typical weather station does not report the actual measured barometric pressure. Rather, it reports a “sea-level corrected” value. The sea-level corrected pressure is not calculated automatically but can be found using this equation:where h is the sensor’s elevation in meters and BP is the Barometric Pressure in mbar. To have this calculation done automatically, type this equation into the Calculator tool in PASCO Capstone or SPARKvue.

Wireless GPS Sensor

The Wireless GPS Sensor uses signals received from the Global Positioning System (GPS) to determine its latitude, longitude, altitude, and horizontal velocity anywhere on Earth. This sensor can be used alone or in conjunction with other sensors for outdoor experiments in environmental science, physics, and other subjects. Data from the Wireless GPS Sensor can be relayed via Bluetooth or micro USB cable to PASCO Capstone or SPARKvue.

Theory of operation

The Wireless GPS Sensor must receive data from at least three GPS satellites to determine its position. When the sensor is first powered on, it searches the sky for available satellites. This process typically takes between 30 seconds and 2 minutes. Once satellites have been identified, the sensor actively tracks them and acquires new satellites as they come into view. The Wireless GPS Sensor performs best outdoors, with a clear view of the sky.
Sensor set-up
Orientation and positioning
It is important to orient the sensor properly to receive signals from satellites overhead, especially during initial search mode (when the GPS Status LED is blinking red). The antenna detects signals through the top side of the sensor. The antenna is located above the rectangular window which houses the temperature, pressure, and humidity sensing elements. Hold the sensor with the top side up and approximately horizontal, facing the sky. Do not cover the antenna area.
Modes
The color of the GPS Status LED indicates whether or not the sensor is ready to make measurements. At initial power on, the sensor enters “search mode”, in which it searches the sky for available satellites. During “search mode”, the LED blinks red. When the sensor is actively tracking three or more satellites, the LED blinks green. If the sensor cannot track at least three satellites, it enters “lost mode”. In this mode, the sensor continues to report its most recent position measurements. Use this “stale” data with caution, as it is incorrect if the sensor has moved since its last valid measurement. In lost mode, the GPS Status LED blinks red and the sensor searches for available satellites again.
If the Wireless GPS Sensor is turned off in the data collection software, or if there is a hardware problem, the GPS Status LED does not shine.

Wireless Light Sensor

The Wireless Light Sensor measures four quantities: Illuminance, Ultraviolet Index, Solar Irradiance, and Solar PAR.

•  Illuminance is a measure of the amount of light that reaches a surface. It is reported in lux (lx), also called lumens per square meter.
• The Ultraviolet Index, or UV Index, is a linear scale measurement proportional to the amount of ultraviolet radiation the sensor detects; this value indicates the time it takes for harm to occur due to ultraviolet radiation in the vicinity of the sensor. The UV Index does not include a unit.
• Solar Irradiance refers to the amount of power the sun’s light delivers to a given area. Solar irradiance can be reported in W/m2 (watts per square meter), mW/m2, µW/m2, or µW/cm2.
•  Solar PAR (Photosynthetically Active Radiation) measures the number of photons within the range of wavelengths conducive to photosynthesis which fall on a given surface area per second. Solar PAR can be reported in µmol/m2/s (micromoles per square meter per second) or mol/m2/s.

For greatest accuracy when using the Wireless Light Sensor, ensure that the white disk on top of the sensor is clean and dry.
Wireless Compass
The Wireless Compass measures Magnetic Heading and reports it in either degrees (°) or radians (rad). In addition, the Wireless Compass provides two calculations based on the magnetic heading: Wind Direction and True Heading, both of which have the same unit options for reporting data.

• Wind Direction: When used with the PS-3553 Weather Vane Accessory, this calculation accurately measures the direction of the wind relative to magnetic north.
• True Heading: This calculation combines the Wind Direction with the GPS position data to measure the direction of the wind relative to true north.

Battery life

Battery usage

Battery life is very important to making the Wireless Weather Sensor simple and always ready to use. Therefore, this sensor, like all PASCO wireless products, is designed for long battery life. For example, after a brief time of inactivity, the Weather Sensor turns itself off to conserve battery life. The battery life between charges for the Weather Sensor ranges from two days to more than a week, depending on active sensors and sample rate. If the Battery Status LED blinks red, connect the Weather Sensor to the USB Charger or a USB port.
Maximizing battery life
One of the factors that affects battery life is the storage temperature. Therefore, avoid storing the Weather Sensor in very cold or very hot environments. If the battery will not hold a charge, contact PASCO Technical Support.
Replacement items
The wind turbine of the Wireless Weather Sensor with GPS can be replaced with the PS-9879 Impeller Replacement Anemometer. Check with Technical Support regarding possible replacement items.
