This project is a simple and effective Rain Alarm System built using a Darlington Transistor Pair for signal amplification. The system detects water droplets (rain) and triggers a buzzer or LED alert.

Recent technological advances have enabled the development of a wide range of increasingly sophisticated wearable and implantable devices, which can be used to monitor physiological signals or ...

Abstract: The advent of Light-Emitting Transistors (LETs) represents a groundbreaking advancement in the realm of optoelectronics, achieved through the incorporation of quantum-wells (QWs) into the ...

A recent Design Idea presents a circuit to measure an airflow rate up to 2000 fpm using two transistors in a Darlington configuration. One transistor works as a self-heated thermal sensor and the ...

Self-heated thermal airflow sensors are simple, cheap, rugged, and sensitive. However, they exhibit an airspeed to sensor temperature response (King’s Law) that is very nonlinear, as shown in Figure 1 ...
