How to Use Diodes, Transistors, ICs as Temperature Sensors
Normally we find thermistors being used as the sensor for detecting and monitoring temperatures in electronic circuits. However, ordinary semiconductor components like transistors and diodes actually work better than thermitors […]
Motion Detector Circuit using Doppler Effect
The motion sensor circuit explained in the article works by using doppler shift principle, in which the moving target is detected through the continuously varying frequency, reflected from the moving […]
Precision Current Sensing and Monitoring Circuit using IC NCS21xR
If you are looking for current shunt monitors or current sense amplifiers then you have landed at the right page. Current shunt monitor is an instrumentation amplifier which senses the […]
Simple Touch Operated Potentiometer Circuit
In this touch operated potentiometer circuit we have two touch pads, which produce a slowly increasing voltage at the output when one touch pad is touched, and a decreasing voltage […]
Photodiode, Phototransistor – Working and Application Circuits
Photodiodes and phototransistors are semiconductor devices which have their p-n semiconductor junction exposed to light through a transparent cover, so that external light can react and force an electrical conduction […]
