Valarm is an Android app that interfaces with Yoctopuce USB sensors and modules to monitor:
- VOCs (volatile organic compounds)
- Ambient temperature
- Relative humidity
- Barometric pressure
- Solar radiation
- Any sensor using electrical resistance
Valarm is an Android app and integrated web tools suite that gathers real time environmental data using external sensors. For example, a farmer can place a Valarm-based sensor web on their farm and compare plant health with micro-environmental phenomena related to the topography of the study landscape. Similarly, a Valarm sensor web can be configured to study preferable locations for solar power generation sites or to monitor air quality (CO2 and VOCs) anywhere in the world or perform other land use land cover (LULC) analysis and mobile data acquisition.
Furthermore, a Valarm device can be used without a network connection as a spatio-temporal data logger. This means the device can be retrieved later then the data is downloaded and further analyzed.
