It is also possible to build an electronic circuit with breadboards and zero boards, but the method is a low level and...
by Tarun Agarwal 10 years ago ZigBee Technology Architecture and Its Applications In this present communication world, there are numerous high data rate communication standards that are available, but none of these meet the sensors’ and control devices’ communication standards. These high-data-rate communication...
by Tarun Agarwal 10 years ago Simple Water Level Controller Circuit with Microcontroller and Alarm Nowadays many houses store water in underground tanks and pump the water to the overhead tanks. At times, the water overflows from the overhead tank leading to wastage of water. To overcome this problem, a water-level indicator with an...
by Tarun Agarwal 10 years ago Basic Types of Three-Phase Motor Protection Systems and Operations Due to the robust construction and ease of control, three-phase asynchronous motors are widely preferred over many other motors for the AC motor-driven applications. This three-phase motor is accountable for larger load operations in several...
