“…However, at high RH levels (above 90%), the dielectric material of the capacitive sensor can be saturated by water vapour, which implies a significant error in the RH measurement together with an uncertainty increase equal to ±6% [26]. Thus, in 2015, the thermo-hygrometers were replaced by a new generation of instruments (distributed by Rotronic HygroClip R HC2-S(3)-HEATED) that use heated capacitive sensors to avoid saturation of the dielectric material [14]. All of the sensors were connected to the GRILLO MMTS data logger for data transmission to a cloud server for real-time visualisation and remote download.…”

The peculiar microclimate inside cultural hypogeal sites needs to be carefully investigated. This study presents a methodology that aimed at providing a user-friendly assessment of the frequently occurring hazards in such sites. A Risk Index was specifically defined as the percentage of time for which the hygrothermal values lie in ranges that are considered to be hazardous for conservation. An environmental monitoring campaign that was conducted over the past ten years inside the Mithraeum of the Baths of Caracalla (Rome) allowed for us to study the deterioration before and after a maintenance intervention. The general microclimate assessment and the specific conservation risk assessment were both carried out. The former made it possible to investigate the influence of the outdoor weather conditions on the indoor climate and estimate condensation and evaporation responsible for salts crystallisation/dissolution and bio-colonisation. The latter took hygrothermal conditions that were close to wall surfaces to analyse the data distribution on diagrams with critical curves of deliquescence salts, mould germination, and growth. The intervention mitigated the risk of efflorescence thanks to reduced evaporation, while promoting the risk of bioproliferation due to increased condensation. The Risk Index provided a quantitative measure of the individual risks and their synergism towards a more comprehensive understanding of the microclimate-induced risks.

“…A new technology was developed to solve these problems and modernise the agricultural irrigation installations, the capacitive sensors [8][9]. The main advantage of this technology is a response time less than one minute which permits a real-time monitoring on the hydric state of the soil [10]. But their complex design [11][12] does not make them easy to use and deconstructs the soil when they are placed.…”

The new methods for the agriculture have to improve the irrigation systems. Nowadays, an important part of irrigation water is wasted. A new connected agriculture needs to reduce that wastage by creating a sustainable agriculture. To achieve that goal, we need to control the soil moisture to perfectly adapt the water supply. This paper presents a new connected sensor to monitor in real time the irrigation impact on the fields. The challenges for this new system are the ease of installation, the cost and the network coverage. This work describes the design of this system and its results in fields.
