SR04 Ultrasonic Sensor Features The SRF04 ultrasonic distance sensor can be used to measure distance with high accuracy. The basic working principle of this sensor is that it produces a high-level signal and sends it to the obstacle. Then the receiver detects the returned wave. The time between the transmission and reception of the signal allows us to calculate the distance to an object. Note When the Trig pin is set High, the sensor generates and sends ultrasonic sound. At that moment the Ech...

Piezoelectric Vibration Sensor Features Piezoelectric vibration sensor is based on piezoelectric ceramic sheet. This sensor uses piezoelectric ceramics to generate vibration. When the piezoelectric ceramic piece vibrates, an electrical signal is generated.This sensor has two digital and analog outputs. The greater the vibration intensity, the higher the analog output voltage. Vibration amplitude sensitivity can be adjusted by the potentiometer. Note When the sensor vibrates, the digital outpu...

HW-M10 Microwave Sensor Module Features The HW-M10 microwave sensor module is very accurate and widely used for motion detection in alarm and security systems. This module, like the PIR module, can detect any movement. The only difference is that instead of using radiation emitted by or reflected from objects, it uses microwave Doppler radar technology. This module has a digital output that is normally Low and becomes High (3.3V) if it detects motion and remains High for 2 to 3 seconds. ...

Overview Have you ever wanted to use 2 sensors with the same I2C address at the same time, not knowing what to do? Faced some serious challenges in doing that? In a lot of projects, we have used different modules and sensors that support I2C communication protocol. Sometimes, we have interfaced some I2C modules with a microcontroller in our projects. If they all have different I2C addresses, we could easily interface them, facing no serious trouble. But, if 2 or more of the modules had the same I2C address...

Overview Sometimes in electronic projects, you need to use two or more microcontrollers in your circuit at the same time. Normally, these microcontrollers are connected to each other and keep transmitting data with one another. The transmitting of data between two or more microcontrollers can be done with several communication protocols such as SPI, UART, CAN, USB, etc. Another one which we will be covering here in this tutorial is I2C (Inter-Integrated Circuit) protocol. Using this protocol, one of the mi...

Introduction In this tutorial, we will explore the potential of infrared (IR) technology and how it can be utilized with an Arduino. Infrared communication is a common feature in electronic devices that allows wireless information exchange. IR technology is everywhere, from remote controls to automatic doors. Understanding the principles of IR communication and learning how to work with it will open up a wide range of possibilities. This tutorial will help you send and receive IR signals with an Arduino...
