How Temperature Measurement Helps Save Energy

Did you know? Lowering the room temperature by just 1 degree can save up to 6 percent of energy. It's worth paying close attention when heating. With the integrated thermometer in our weather stations and thermo-hygrometers, you can always keep an eye on the current room temperature – allowing you to adjust your heating habits to save energy. Has the temperature reached a level that's comfortable for you? Then the thermostat can be turned down a bit to maintain the room temperature and save money.



Practical everyday helpers: Some models also offer a high-low temperature alarm that alerts you with a sound when your individually set temperatures are reached. Our modern Smart Home weather stations take it a step further: based on the measured values, these devices can automatically regulate your heating through an app and your existing Tuya thermostats. Saving energy can be that simple!


Why Get a Weather Station for Your Home?

Storm surges, hurricane-force winds, and heat waves – climate change is becoming increasingly noticeable. Even in Germany, we are experiencing more frequent meteorological changes. And the trend is rising!

Why is it worth having a weather station at home when weather apps are available? BRESSER's product manager for consumer electronics, Dominik Becker, answers this and other interesting questions in an interview for you.

Product information "BRESSER HCHO + VOC Sensor"

NATIONAL GEOGRAPHIC VA Colour LCD Weather Station incl. 3 Sensors
The NATIONAL GEOGRAPHIC VA colour weather station with 4 measuring points in black displays all relevant weather data at a glance. The set includes 3 outdoor sensors and one built-in sensor. On the clearly arranged colour display you will find information such as temperature and humidity for indoor as well as outdoor, as well as the exact time via DCF radio transmission. Besides the built-in sensor in the console unit (display) the station is able to receive the temperature and humidity readings from three additional sensors which are included in this set. Its use is therefore very versatile as the sensors can be placed either in- or outdoors. What's the temperature in the kids room, is the basement too moist how cold is it outside? All these questions can be viewed on one display. The station has a time offset function, so although parts of the UK are technically able to receive the European DCF time signal (southern England), your station will be displaying the UK time. For all parts of the UK where the time signal can not be received the time can easily be set manually with this station. The featured weather forecast is for the coming 12-24h. FEATURES BASE STATION LCD colour display Indoor temperature (°C/°F) and humidity Outdoor temperature (°C/°F) and humidity Display of time, date and weekday Time by DCF radio signal with time offset function for the UKWeather Forecast Maximum connectable sensors: 3 (3x included!) Hanging device and stand Power supply: Power plug with UK adapter (included) FEATURES SENSOR Measurement of outdoor temperature (°C / °F) and humidity LCD displayRange up to 80 m Can be placed on a table or wall-mountedPower supply: 2x AAA batteries per Sensor (not included)  Dimensions: 71 x 65 x 23 mm; weight: 44 gSCOPE OF DELIVERY Weather station 3x outdoor sensors Instruction manual

BRESSER PM2.5 / PM10 Particulate Meter with Wireless Sensor
Particulate matter: invisible yet always present. In large amounts, these small particles in the air can be harmful to our respiratory system. With the BRESSER PM 2.5 / PM 10 particulate meter, you can take control of monitoring the air quality. The European limits and WHO recommendations for air quality are regularly exceeded, especially in big cities. Heavy traffic, industry and agriculture significantly increase the concentration of particulate matter. To let you know when the air quality is poor, the particulate meter's wireless sensor takes precise measurements of two types of particulate matter that can be harmful to your health: Particles with a diameter of less than 10 μm (PM10) and less than 2.5 μm (PM2.5). The excellent sensor made by the renowned Swiss manufacturer Sensirion guarantees very precise measurement results. Thus, the particulate meter is also the perfect source of information for people with allergies in order to keep an eye on the pollen count. And you don't need to be an expert in order to determine whether the readings are within a healthy range: The air quality index shows you in 6 colour-coded levels whether the air is clean. Historical air quality data The damage that air pollution does to our health doesn't happen overnight. The particulate matter meter therefore records a range of historical readings, including the maximum readings from the past hour and 24 hours, and the overall historical maximum, to give you better idea of trends in the air quality. To view the current reading - regardless of the measurement interval settings - simply press the button on the sensor. The device also features a high alarm function: simply configure your desired limit for particulate matter and the alarm will sound when the limit is reached. If you normally measure the air quality indoors, but want to know whether the air is clean before you spend a sunny day in the garden, you can use the wireless sensor. The wireless sensor can also be used individually and shows you the particulate matter readings on the built-in display. Armed with this sensor, you can measure particulate matter both indoors and outdoors. Also ideal for travelling! Particulate matter meter with fresh air function Good air quality is about much more than clean air. A good indoor climate is also essential for our wellbeing. For this reason, the particulate matter meter also features a built-in thermo-hygrometer so that you can monitor your indoor climate in more detail. If you have mould stains in your bathroom or the air in your child's bedroom is too dry when you turn the heating on, you can take preventive measures by referring to the indoor temperature and humidity readings on the base station. What's more, if you put the air quality meter in your bedroom, it can also double up as an alarm. Simply set the time at which you want to get up and enjoy your well-earned sleep until the alarm goes off. If you want a few extra minutes in bed, you can press the snooze button to silence the alarm for 5 minutes. Monitor your air quality - with the BRESSER PM 2.5 / PM 10 particulate meter. BASE STATION FEATURES Very precise air quality meter with wireless sensor Easy to use PM2.5/PM10 air quality index (AQI) with colour coding Ideal for people with allergies to keep an eye on the pollen count Records the maximum values from the past hour and past 24 hours, as well as the overall historical maximum High alarm function Alarm function with snooze button Measures the indoor temperature (°C/°F) and humidity Amber-coloured LED backlight Supports up to four PM2.5/PM10 wireless sensors Power supply: 2x AA batteries (not included) Installation: Wall or stand SENSOR PROPERTIES Precise indoor and outdoor PM2.5/PM10 measurements Swiss precision technology: fine particulate matter sensor made by Sensirion Built-in display Can be used independently High range of up to 150 m Battery indicator Power supply: 3x rechargeable AA batteries (included), rechargeable with USB cable (included) Installation: Wall or stand DELIVERY CONTENT Base station PM2.5/PM10 wireless sensor 3x rechargeable AA batteries USB cable
