MAST Weather Station
Live environmental readings from the AwareSTEM mast — temperature, humidity, pressure, air quality, particles, light, sound and lightning, updated in real time from Doncaster, UK.
🌡 Temperature
Air temperature in degrees Celsius measured by the BME688 sensor. Normal UK outdoor range is roughly -5°C in winter to 30°C in summer. The BME688 is more accurate than a basic DHT11 sensor.
💧 Humidity
Relative humidity — how much water vapour is in the air as a percentage of the maximum possible at that temperature. Below 30% feels dry, above 70% feels muggy. High humidity combined with heat makes it feel hotter than it is.
🌞 Pressure
Atmospheric pressure in hectopascals (hPa). UK average is around 1013 hPa. Rising pressure usually means improving weather is on the way. Falling pressure often signals rain, wind or storms approaching.
🩻 PM2.5 Fine Particles
Particles smaller than 2.5 micrometres — so tiny they can enter your lungs and bloodstream. Main sources are vehicle exhaust, wood burning and industrial pollution. WHO guideline is below 15 μg/m³ annual average. Good air is typically below 12 μg/m³.
🩻 PM10 Coarse Particles
Larger particles up to 10 micrometres — dust, pollen, mould spores. Still harmful to breathe but filtered more easily by the nose and throat than PM2.5. WHO guideline is below 45 μg/m³. Good air is typically below 20 μg/m³.
☀ Light Level
Digital light detection — 0 means light detected, 1 means dark or sensor covered. Useful for tracking daylight hours and detecting sudden changes like cloud cover or night falling.
🔊 Sound Level
Ambient sound level from an analogue microphone sensor. Higher values mean louder environment. Useful for tracking background noise levels — wind, traffic, storms. Spikes during lightning are common.
⚡ Lightning Distance
The AS3935 chip detects the electromagnetic pulse from a lightning discharge and estimates how far away it is in kilometres, up to 40km. It detects distance but not direction, so the map shows a ring — the strike is somewhere on that circle around Doncaster.
