This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

The Gulf of Maine—home to commercial fisheries for oysters, clams and mussels—has unexpectedly avoided an increase in seawater acidity, helping to preserve the health of its fisheries. The Gulf's ...

Recently I was looking for an inexpensive pressure + temperature sensor for a barometric altimeter project, which then led to me finding the SPL07-003. After learning there was no existing library to ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...

(Nanowerk Spotlight) Inside a wound, a complex chemical battle unfolds. As healing progresses, the wound environment shifts between acidic and basic states, each change signaling different stages of ...

Insulin is a peptide hormone secreted from pancreatic beta cells to regulate blood glucose homeostasis. Maturation of active insulin occurs within insulin secretory granules (ISG) by acidification of ...

IoT and wearable devices have become essential tools in our everyday lives. From health monitoring wearables to smart home sensors, they rely heavily on battery power to function. However, optimizing ...

Abstract: The pH value in bodily fluids is a crucial diagnostic marker. Conventional glass-rod pH sensors display reliability in aqueous solutions, but the pH-sensitive glass membrane makes them prone ...

Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been working since the release of the ESP-IDF 5.1 ...
