Improper warming, leakage, and water heater damage can cause malfunctioning thermostats. In this post, we will…
Lithium-ion 21700 batteries are part of high-drain devices that provide a voltage range of 3.6 to 3.7 volts and are used where constant voltage is needed and also provide a low self-discharge rate and larger charging and discharging cycles. 21700 lithium rechargeable batteries have different chemistry, battery capacity, and maximum pulse for different types. In…
Hi, friends, welcome to the new post. In this post, we will learn what a cold solder joint is and how you can prevent it. Soldering is a technique commonly used in electronics and electrical work. It helps to make connections between different components. In some conditions, the soldering process can cause fault connections that…
Hi, guys, welcome to the new post. In this post, we will learn what an anemometer measures. Meteorologists use different techniques to measure wind speed. To measure the wind speed, there are instruments used called an anemometer. An anemometer measures wind speed in miles per hour, kilometers per hour (KpH), meters per second (m/s), or…
Hello readers, welcome to the new post. In this post, we will learn about the ESP32 vs. the ESP8266—Which One to Choose? Both the ESP32 and ESP8266 are low-cost, Wi-Fi-based SOCS best for DIY projects in IoT. These come with 32-bit processors: the the ESP32 is a dual-core 80Mhz to 240MHz CPU, and the ESP8266 is an…
