Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...
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 ...
As you might have noticed, the 38-KHz pulse generator is built around the evergreen timer chip NE555P (IC1). Here, the RC components (R5-C3-P1) set the astable frequency to drive the infrared light ...
Steute's wireless transmitter-receiver module is designed to control foot and hand switches in medical device applications. As foot and hand controls become increasingly prevalent in doctors' offices ...
This project pairs a set of 8-bit microcontrollers with a 433-MHz industrial, scientific and medical (ISM) band transmitter/receiver. The FS1000A RF transmitter has a range of up to 200 m; the ...
This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...
