There are a lot of options for local weather stations; most of them, however, are sensors tied to a base station, often requiring an internet connection to access all features. [Vinnie] over at ...
Abstract: An electrochemical zinc oxide (ZnO) pH sensor is proposed and prototyped using a flexible printed circuit board (FPCB). The device is resistant to acidic and alkaline solutions and exhibits ...
Abstract: In this work, highly sensitive low-humidity sensors based on Au nanoparticles (NPs)-modified sulfonate metal–organic frameworks (MOFs) were constructed, and the sensor was applied in ...
