Live weather data is fetched through an open weather API by an Arduino MKR WiFi 1010. ... [Build Comics] is using an Arduino Nano and a DHT22 sensor that can detect temperature and humidity.

This Arduino Nano project uses a soil moisture sensor, two potentiometers and a relay to automatically control a device based on soil moisture levels. The relay is turned on below a minimum threshold ...

SMART’s newly developed nano-sensor enables direct, real-time tracking of auxin levels in living plants with high precision. The sensor uses NIR imaging to monitor IAA fluctuations non-invasively ...

Abstract: This paper describes the challenges of nano-scale sensor development for very harsh downhole oilfield conditions and provides an overview of the operational requirements necessary to survive ...

The detection of histamine (HA) is critical due to its significant implications for food safety, public health, and regulatory compliance. In this study, we developed a molecularly imprinted ...

We have designed and implemented a practical nanoelectronic interface to G-protein coupled receptors (GPCRs), a large family of membrane proteins whose roles in the detection of molecules outside ...
