Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...

Abstract: Structural health monitoring (SHM) using wireless sensor networks (WSNs) has gained research interest due to its ability to reduce the costs associated with the installation and maintenance ...

Arduino library for the ENS16x digital four channel MOX gas sensors with I2C/SPI interface from ScioSense. ENS16x is a range of digital multi-gas metal oxide (MOX) sensors, specifically designed for ...

Abstract: Quartz crystal microbalances (QCMs) are devices that have been proven to function as sensors for detecting specific chemical species; this usually requires that the QCM is modified with a ...
