PM2005 Laser Particle Sensor Module Library for Arduino This is a library for the laser particle sensor module PM2005 manufactured by Wuhan Cubic Optoelectronics. The PM2005 module counts airborne ...

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 ...

Code uploadWe can now load our Arduino sketch to the RAK4631 development board.Selected the board in the Arduino IDE, as well as the correct port, and start the code uploading and flashing. You may ...

The main component of a sound sensor is a microphone. There are many different types of microphones, like Carbon Microphone, Fiber Optic Microphone, Ribbon Microphone, and Laser Microphone, but the ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

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 ...

Lasers are some of the coolest devices around. We can use them to cut things, create laser light shows, and also as a rangefinder.[Ignas] wrote in to tell us about [Berryjam’s] AMAZING write-… ...

Connect pins 7 and Gnd of Arduino to pins 1 and 3 of KY-008 module, respectively. Run the first sketch (onoff.ino) to turn the laser on and off every second. Next, connect pin A0 (ADC channel 0) of ...
