“…Since the cheapest ventilation systems might fail to provide the necessary microclimate in the cult buildings, and since the most expensive ventilation systems are often unaffordable due to financial restrictions, we will not consider forced ventilation systems in our research. Ventilation by virtue of automated opening of windows and doors can ensure better and more stable indoor air parameters, while opening the windows when indoor air is too humid and outside air is drier [9]. M. Napp and T. Kalmes performed measurements in the Church of the Holy Cross (EST) with three various climate control methods (adaptive ventilation, conservation heating and dehumidification) and concluded: "Conserved heating with a heat pump showed the lowest annual energy consumption of 29 kWh/(m2•a).…”

There are 320 historical cult buildings as cultural monuments of national significance in Latvia. Cultural and historical art monuments and artifacts (paintings, organs, chairs, altars, pulpits) must be preserved and protected in these cultural buildings. Specific indoor climate is necessary to maintain in historical cult buildings to pass on to future generations, but those specific requirements often are complete opposite of the actual microclimate and what the user wants. Indoor climate measurements have been carried out in five brick wall and two wooden churches with and without heating systems. Potential condensation risks are determined using calculations. Typical air flow has been formed using building’s termography measurements. Heating systems and making use of buildings influence historical buildings and this has been determined. The main aim of the article is to determine potential indoor climate type of control in historical cult buildings avoiding humidification and dehumidification, and it is similar in the coastal climate of the Baltic Sea. Results show that: great humidity fluctuations have been observed in buildings which have been used during winter, outdoor air has a great impact to buildings, less humidity fluctuations have been observed in buildings with controlled heating systems.

The atmospheric parameter sensing is pivotal in the forecasting of the weather. The meteorological parameters like temperature, humidity and pressure are measured with the usage of sensors. The DHT11 sensor is employed for measurement of humidity where as the BMP180 sensor is used for the monitoring of temperature and atmospheric pressure. The sensors are interfaced to NodeMCU ESP-32S module. The humidity sensor is interfaced with the single-wire two-way serial protocol and the pressure sensor is interfaced with the I2C protocol. The Arduino IDE is employed for scripting the software of the system. The developed prototype is connected to IoT with the help of inbuilt Wi-Fi module in the NodeMCU EPS-32S. The data collected is portrayed on a web page developed in the IDE. The system is compact and easy to use with its plug and play nature. The prototype can be deployed over various areas such as home automation, industries, healthcare centers.
