Introduction: Distance sensors are devices designed to measure the distance between the sensor and an object. They find applications in various fields, including robotics, industrial automation, automotive, and consumer electronics. There are several types of distance sensors, each utilizing different principles to accurately measure distances. In this article, we will explore some common types of distance sensors and how they work. 1. Infrared (IR) Sensors: Working Principle: Infrared distance sensors emit infrared light and measure the time it takes for the emitted light to bounce back after hitting an object. The sensor calculates the distance based on the time delay. Application: IR sensors are commonly used in proximity detection and obstacle avoidance systems, such as in robotics and automation. 2. Ultrasonic Sensors: Working Principle: Ultrasonic distance sensors use ultrasonic waves (sound waves with frequencies above the human audible range). The sensor emits ultrasonic

How to differentiate between rechargeable and non rechargeable batteries?

Image
Introduction: Batteries are ubiquitous in our daily lives, powering a wide range of devices from remote controls to smartphones. One crucial aspect to consider when using batteries is whether they are rechargeable or non-rechargeable. Understanding the key differences between these two types is essential for proper usage and disposal. In this article, we will explore the characteristics that differentiate rechargeable and non-rechargeable batteries. 1. Chemical Composition Rechargeable Batteries: Rechargeable batteries , often referred to as secondary batteries, are typically made with materials that allow for reversible chemical reactions. Common materials include nickel-cadmium (NiCd), nickel-metal hydride (NiMH), and lithium-ion (Li-ion). These batteries can undergo numerous charge and discharge cycles without significant degradation. Non-Rechargeable Batteries: Non-rechargeable batteries , also known as primary batteries, are designed for one-time use. They are composed of materia
