Introduction to MAX3232RS232 Serial Port To TTL Converter Module DB9 Connector 5V, RS232 Max-232 is an integrated circuit, used to convert serial data from RS-232 standard to TTL standard. There are three main points to understand while using the module. One is serial data (Serial Communication) , Second one is RS232 standard and third one is TTL standard . Serial communication Embedded electronics is all about interlinking circuits (processors or other integrated circuits) to create a symbiotic system. In order for those individual circuits to swap their information, they must share a common communication protocol. Hundreds of communication protocols have been defined to achieve this data exchange, and, in general, each can be separated into one of two categories: parallel or serial. In telecommunication and data transmission, serial communication is that the method of sending information one bit at a time, consecutive, over a communicating or laptop bus. this can be in ...

Introduction A Float Level Switch is a device which detects the level of water or any liquid in a storage container. It is frequently used as an alarm to indicate the desired level of water or liquid. Also, it can be used as a switch to control a pump also know as Water level sensor . Level sensors also detect the level of liquids inside a container like a float switch. They contain some sort of a built-in electronic or mechatronic system which either monitors level of liquid within a particular range or at a particular point. As any liquid material flows horizontally due to gravity within containers, sensors can be used at specific locations or range to monitor the rise of level of liquid. Mostly, these level sensors are used as a trigger to direct an action when a particular condition is fulfilled eg. When a water tank is full, this water level sensor may trigger the turning OFF of pump, automatically draining out liquid once it has surpassed any limit etc. These floa...
