A two-wire temperature transmitter using an RTD sensor that can be used in industrial settings to connect to the control room.

Off-ramps along Interstate 40 will be closed around the clock to undergo testing of wrong-way detection systems.According to a release, only emergency responder ...

Learn to build an RFID based attendance system using Arduino with step-by-step instructions, circuit diagrams, and complete code. This $35 DIY project replaces expensive commercial systems with ...

The project includes 3D-printed parts, wooden supports, and a repurposed mini conveyor belt.The working combines stepper motors, IR sensors, and a 16x2 LCD.A NEMA17 stepper motor is used to rotate the ...

The Arduino code is located in the arduino-code folder. The code still lacks the ability to measure pressure and it is a mess (I merged several online projects). It measures the pressure in mV. As ...

An easily implementable signal conditioning circuit for resistive humidity and temperature sensors is presented. It is based on a relaxation oscillator in which both the frequency and the duty-cycle ...

Photochromic molecules have been recently adopted by many researchers for organic field-effect transistor (OFET) applications, since they offer the opportunity to achieve flexible-type ultraviolet (UV ...
