I'm trying to make a pair of devices which can measure their distance from each other (within 50 ft., irrespective of orientation). The basics of a robust solution are described in this comment, but I ...
I am a web developer by profession. few days back I lost 8gb pen-drive :( I don't it is in home or somewhere else.... So now I am thinking of a device which can be attached with small objects so that ...
I have followed the tutorial from Makezine about an Infrared heart-beat sensor, and I have essentially used the same components listed on the video (that is, the same resistors and the same IR Emitter ...
I am trying to amplify a MG811 CO2 sensor to a range readable by an ATMEGA2560 (0-5v). I have other analog sensors, so do not want to change ref voltage on Atmega. I have found a module that scales ...
Related: High Resolution ADC for Noisy Sensors in Variable Conditions I'm building an interface using resistive textile-based sensors that may have different resistance ranges depending on ...
For my senior design project, we have various sensors (Thermocouples, Heat flux sensors, load cell) plugged into our DAQ. We are using LabView and some National Instruments devices (ugh) and ...
