ESP-01 is a tiny and useful piece of hardware. It has a 32-bit MCU, 2.4GHz 802.11 b/g/n WiFi, 1MB flash memory, and several other useful embedded features. Such ...
The project has been constructed for applications that require automatic temperature control while providing highly accurate thermal control circuit. The LM35 temperature sensor is the heart of the ...
Nanoelectromechanical (NEM) relays have zero-off state current and a steep subthreshold slope 1,2,3,4,5,6 and can operate at very high temperatures 7. Thus, they have potential to replace transistors ...
Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...
A temperature controller is an instrument that controls temperatures, often without extensive operator involvement. In a temperature controller system, the controller accepts a temperature sensor as ...
Members can download this article in PDF format. In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to ...
Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...
