In this video, I’m building a LoRaWAN Class A sensor node using an ESP8266, BME680 environmental sensor, and REYAX RYLR993 LoRa module. The device measures temperature, humidity, pressure, and gas ...
The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for installation.
A superconducting kinetic inductance detector improves sensitivity limits needed for observing cold astrophysical objects, ...
Near-infrared (NIR) photon detection and object recognition are crucial technologies for all-weather target identification.
