En los últimos años hemos pasado de ver los lectores de huellas como algo de película de espías a llevarlos en el bolsillo todo el día. Desbloqueamos el móvil, autorizamos pagos, abrimos la puerta de ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Connect the VEML6040 sensor to your Arduino board's standard I2C bus. Check the pinout of your Arduino board to find the correct pins. Important: without additional level shifting the VEML6040 is not ...

Arduino library gives user basic communication from sensor to microcontroller via I2C protocol. Please see LICENSE.md for more details. Please use, reuse, and modify these files as you see fit. Please ...

Abstract: The chemiluminescent signal in lab-on-a-chip (LOC) is generally weak and also has a short lifetime, hence, a sensitive and fast detector is required for detection. Aiming for acquisition of ...

Abstract: This paper shows a system and a method for indoor positioning based on the LED lighting installed on the environment. The proposal is based on the modulation of the visible light signal ...
