This article will introduce the WisBlock RAK12014 ToF laser ranging sensor module, and use the WisBlock development board to demonstrate how the module works. What is a ToF laser ranging sensor module ...

O Sensor de Segurança a Laser utiliza o módulo LDR para detectar se o feixe de luz do laser está sendo interrompido. Quando o feixe de luz é bloqueado, o módulo LDR registra a mudança na intensidade ...

So, the receiver program is to be uploaded two times in Arduino Nano board. There are two source codes: Labtesttxnode.ino code for sensor node and LabtestRx.ino code for receiver. The ...

The laser hits the light sensor, which registers a certain value. When something interrupts the laser, the value drops and the buzzer starts producing sounds. If key 1 is pressed three times on the ...

Laser Blaster Last Updated: 7/27/18 Teaching Standard: In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates ...

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 sensor was ...

The UK government has awarded a £180K grant to Sentinel Photonics to develop a sensor to detect and identify laser threats in civilian contexts. The original technology was created by the Dstl ...

This device can be useful by rice field owners to decrease the number of pests in rice fields, also this will provide a non-chemical and energy saving way utilizing UV LEDs to attract bugs and ...
