+### Temperature
+**Temperature** plays a crucial role in weather prediction as it directly influences the atmospheric dynamics, moisture, pressure systems and other meteorological phenomena. Any kind of weather model relies analysis of temperature patterns to define the state of the atmosphere. It drives the motion of air and the formation of weather systems due to its effects on pressure gradients. Higer temperature result in warmer air, while lower temperatures result in colder air. Heat energy from the sun warms the surface of the Earth differently across regions, which create temperature gradients. This then helps to forecast sea breezes, storms and movement of air. Temperature measured in a vertical profile is also important since it determines the stability of the atmosphere and if the conditions pull more towards thunderstorms or cloud formation. Temperature trends are highly essential for seasonal and-long term forecasting.

+**Humidity** is a measure of amount of water vapor in the air, gaseous form of water. Humidity is another crucial factor for atmospheric processes, such as cloud formation, precipitation, and temperature regulation. It affects the amount of water vapor in atmosphere. Three main terms to be aware of when it comes to humidity is:
+
+* **Absolute humidity** - measures the total amount of water vapor in a given air volume
+* **Relative humidity** - indicates how much more water vapor the air currently holds compared to the maximum amount it could hold at a specific temperature
+* **Dew point** - the temperature at which air becomes saturated and condensation begins
+
+Humidity affects cloud formation the most. If it is high, the possibility of cloud formation is higher, increasing the likelihood of precipitation.
+
+### Atmospheric pressure
+[**Atmospheric or air pressure**](https://iere.org/how-does-the-air-pressure-affect-the-weather/) is the force exerted by the weight of air above a given point. As everything else regarding weather, the pressure is also not uniform accross the Earth, and these differences kickstart every atmospheric movement. It is important to understand the difference between **high-pressure** (anticyclones) and **low-pressure** (cyclones) system in order to understand the weather conditions. High air pressure indicates that air is descending. As it sinks, it gets warmer and dryer, preventing forming of clouds and leading to clear skies and pleasent weather with calm winds. Low air pressure indicates ascending air which is getting colder with height leading to condensation, cloud formation and precipitation.
some optional text suggestions:
accross -> across
these differences kickstart every atmospheric movement -> these
differences drive atmospheric motion
(cyclones) system -> (cyclones) systems
warmer and dryer -> warmer and drier
preventing forming of clouds -> preventing cloud formation
pleasent -> pleasant

+## Hardware setup
+
+SensEdu shield has integrated barometric pressure sensor that can measure both pressure and temperature. For humidity measurement, we use a third party sensor SHT35 from Sensirion on a custom pcb adapter board for SensEdu. The full list of components includes:
+
+* Arduino GIGA R1
+* SensEdu shield
+* SensEdu platform for humidity sensor
+* USB-c cable
USB-C

+
+## Software setup
+
+### Communication and Data acquisition
+
+Both sensors use I2C communication protocol. I2C protocol allows for one master and multiple slave devices. In this case, the master device is Arduino powered with STM32 microcontroller and the slave devices are two mentioned sensors. Each sensor has a unique address with which they are accessed. The communication is done in the background using **Arduino "Wire.h" library**.
+
+Barometric pressure sensor has a default address of 0x77 (pull-up configuration), and it can be changed to 0x76 with the pull-down configuration. Pull-up configuration refers to SDO pin being pulled-up to VDD or keeping it floating, while pull-down configuration refers to pulling-down the SDO pin to GND. This is done by changing the position of the jumper J19 on Sensedu board.
+
+Similarly, the default address for SHT35 humidity sensor on PCB costumized for Sensedu is 0x44 since ADDR pin is connected to logic low (GND) and cannot be changed. If it would be connected to logic high, the I2C address would be 0x45.
+
+{: .NOTE}
+Since both sensors are connected to SDA1 and SCL1 pins, when using the Wire.h library functions, Wire1.begin() has to be used for I2C1 and Wire2.begin() for I2C2. More information about this can be found in the library [ documentation webpage](https://docs.arduino.cc/language-reference/en/functions/communication/wire/).
+
+Moreover, to interact with SHT35 sensor, we use third party (developed by the company) Arduino library that can be found on [GitHub](https://github.com/Sensirion/arduino-sht/tree/master) and it is free for download. For the barometric pressure sensor, DPS310, we also use Arduino library (developed by Infineon) available on [GitHub](https://github.com/Infineon/arduino-xensiv-dps3xx/tree/master).

Heat energy from the sun warms the surface of the Earth differently across regions, which create temperature gradients. This then helps to forecast sea breezes, storms and movement of air. Temperature measured in a vertical profile is also important since it determines the stability of the atmosphere and if the conditions pull more towards thunderstorms or cloud formation. Temperature trends are highly essential for seasonal and-long term forecasting.

+### Humidity
+**Humidity** is a measure of amount of water vapor in the air, gaseous form of water. Humidity is another crucial factor for atmospheric processes, such as cloud formation, precipitation, and temperature regulation. It affects the amount of water vapor in atmosphere. Three main terms to be aware of when it comes to humidity is:
+
+* **Absolute humidity** - measures the total amount of water vapor in a given air volume
+* **Relative humidity** - indicates how much more water vapor the air currently holds compared to the maximum amount it could hold at a specific temperature
+* **Dew point** - the temperature at which air becomes saturated and condensation begins
+
+Humidity affects cloud formation the most. If it is high, the possibility of cloud formation is higher, increasing the likelihood of precipitation.
+
+### Atmospheric pressure
+[**Atmospheric or air pressure**](https://iere.org/how-does-the-air-pressure-affect-the-weather/) is the force exerted by the weight of air above a given point. As everything else regarding weather, the pressure is also not uniform accross the Earth, and these differences kickstart every atmospheric movement. It is important to understand the difference between **high-pressure** (anticyclones) and **low-pressure** (cyclones) system in order to understand the weather conditions. High air pressure indicates that air is descending. As it sinks, it gets warmer and dryer, preventing forming of clouds and leading to clear skies and pleasent weather with calm winds. Low air pressure indicates ascending air which is getting colder with height leading to condensation, cloud formation and precipitation.
some optional text suggestions:
accross -> across
these differences kickstart every atmospheric movement -> these
differences drive atmospheric motion
(cyclones) system -> (cyclones) systems
warmer and dryer -> warmer and drier
preventing forming of clouds -> preventing cloud formation
pleasent -> pleasant

+## Hardware setup
+
+SensEdu shield has integrated barometric pressure sensor that can measure both pressure and temperature. For humidity measurement, we use a third party sensor SHT35 from Sensirion on a custom pcb adapter board for SensEdu. The full list of components includes:
+
+* Arduino GIGA R1
+* SensEdu shield
+* SensEdu platform for humidity sensor
+* USB-c cable
USB-C

+## Software setup
+
+### Communication and Data acquisition
+
+Both sensors use I2C communication protocol. I2C protocol allows for one master and multiple slave devices. In this case, the master device is Arduino powered with STM32 microcontroller and the slave devices are two mentioned sensors. Each sensor has a unique address with which they are accessed. The communication is done in the background using **Arduino "Wire.h" library**.
+
+Barometric pressure sensor has a default address of 0x77 (pull-up configuration), and it can be changed to 0x76 with the pull-down configuration. Pull-up configuration refers to SDO pin being pulled-up to VDD or keeping it floating, while pull-down configuration refers to pulling-down the SDO pin to GND. This is done by changing the position of the jumper J19 on Sensedu board.
+
+Similarly, the default address for SHT35 humidity sensor on PCB costumized for Sensedu is 0x44 since ADDR pin is connected to logic low (GND) and cannot be changed. If it would be connected to logic high, the I2C address would be 0x45.
+
+{: .NOTE}
+Since both sensors are connected to SDA1 and SCL1 pins, when using the Wire.h library functions, Wire1.begin() has to be used for I2C1 and Wire2.begin() for I2C2. More information about this can be found in the library [ documentation webpage](https://docs.arduino.cc/language-reference/en/functions/communication/wire/).
+
+Moreover, to interact with SHT35 sensor, we use third party (developed by the company) Arduino library that can be found on [GitHub](https://github.com/Sensirion/arduino-sht/tree/master) and it is free for download. For the barometric pressure sensor, DPS310, we also use Arduino library (developed by Infineon) available on [GitHub](https://github.com/Infineon/arduino-xensiv-dps3xx/tree/master).

even with zoom these pictures are not really visible
you should probably crop them to contents and maybe last two pics can be
merged into one with side by side showcase
