The Arduino Uno Laser Sensor Module detects the presence or interruption of a laser beam. It typically includes a laser emitter and a photodiode sensor. When the beam is obstructed, the sensor ...

So, with just two cheap modules, you can build a laser proximity sensor—whether it is the thru-beam type or the reflective type. But I will not go into the build ideas as there are countless tutorials ...

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

Laser particle detectors are a high-tech way for quantifying whats floating around in the air. With a fan, a laser, and a sensitive photodetector, they can measure smoke and other particulates in r… ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...
