Among the many methods available for air flow detection, self-heated thermal flow sensors are simple, cheap, rugged, and sensitive. They rely on the relationship between airspeed (AF) and thermal ...
This self-heated constant-temperature-delta transistor anemometer is cheap, rugged, and sensitive. It relies on the relationship between airspeed (AF) and thermal impedance (ZT = o C/W) of a heated ...
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.
