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 when it comes to detecting temperature changes. In fact, this feature happens to be one of the greatest drawbacks of semiconductor devices, whose working characteristics […]
Programmable Temperature Controller Circuit with Timer
Here I have explained about a circuit configuration which produces adjustable sequential timing outputs for controlling a heater device through a simultaneously sequencing temperature controller circuit which can be also pre-programmed for acquiring the desired temperature levels across the sequencing time slots. The idea was requested by Mr. Carlos Technical Specifications I’m Carlos and I […]
