Wireless Weather Sensor Redy

Quick Answer: The Redy wireless weather sensor is a data-logging sensor for recording weather conditions over time, with readings sent wirelessly to a connected device. A wireless weather sensor turns a school weather log from occasional readings into a continuous record.

Several Weather Variables in One Logging Unit

Weather sensors in educational data-logging ranges commonly combine air temperature, relative humidity and barometric pressure in one housing, and some add derived values such as dew point. The title does not list the parameters, so establish exactly which ones this unit records before building a scheme of work around it.

What a logging weather sensor offers over a wall thermometer and barometer is the unbroken record. Left on a sheltered sill or in a louvred screen for a week, it captures overnight cooling, humidity climbing before rain and the slow fall in pressure as a low approaches. Carried around the school site, it reveals microclimates: a courtyard out of the wind, warmth beside a sunny wall, the cool shade under trees.

If pressure is among its readings, a reading on the ground floor and another at the top of a building let students estimate the height between them, since air pressure falls with altitude. Indoor air-quality projects can pair it with the wireless CO2 air sensor.

Applications

• Keeping a school weather log across a week or a term
• Microclimate surveys around the school grounds
• Relating humidity and temperature changes to dew and mist
• Estimating building height from the change in air pressure between floors, where pressure is recorded

Care & Handling

• Place the sensor in shade with free airflow; direct sun heats the housing and gives false temperatures.
• Protect it from rain unless it is stated to be weatherproof.
• Let it settle for several minutes after moving between indoor and outdoor air.
• Bring it indoors in freezing or stormy weather if its outdoor rating is unknown.

Geography and environmental science departments setting up a school weather station, and physics teachers covering air pressure, are the typical buyers. The sensor is listed by LabEquip within its chemistry lab equipment; ask for the parameter list on the contact page.

Frequently Asked Questions

Which weather variables does the sensor measure?

The title does not list them. Weather sensors of this kind commonly measure temperature, relative humidity and barometric pressure, so ask for the parameter list when you enquire.

Where should a weather sensor be placed outdoors?

In shade, a metre or more above the ground, with air moving freely around it, ideally inside a louvred screen. Avoid walls, paving and car parks, which store heat and distort temperature readings.

Why does relative humidity rise at night?

As air cools it can hold less water vapour, so the same amount of vapour becomes a larger share of the maximum. When the temperature falls to the dew point, dew or mist forms.

How can air pressure help forecast the weather?

A steady fall in pressure over several hours often comes before unsettled, wetter weather, while rising pressure tends to bring settled conditions. Logged pressure makes these trends easy to spot.

Why do indoor and outdoor readings differ so much?

Buildings are heated, shaded and sheltered, so indoor air is usually warmer, drier in winter and still. For a true outdoor record, the sensor must be outside in a ventilated, shaded spot.

Can the sensor be used for fieldwork away from school?

Yes, if the connected device travels with it or the sensor can store readings until it reconnects. Note the place and time of each reading so microclimate results can be mapped.
