humidity controller
humidity control controller is with wide humidity measuring range and controlling range, comes with a humidity controller sensor probe with cable. Hunidity sensor uses a high-precision capacitive faster chip which has the advantage of high accuracy to refect. Humidity measuring range is 1 percent ~ 99 percent rh and control range is 1 percent rh. […]
room temperature controller
Depending on the outside temperature and the heating habits of residents, the heating requirements of rooms, apartments and entire buildings are constantly changing. Radiator thermostats and room temperature controller systems compensate for these fluctuations, keeping the temperature in every room at the level individually set by the resident. Design of a room temperature and humidity […]
3 phase supply
The power delivered by a single-phase system pulsates and falls to zero during each cycle, whereas the power delivered by a three-phase circuit also pulsates, but never to zero. In a balanced three-phase system, the conductors need be only about 75% the size of the conductors for a single-phase two-wire system of the same kVA […]
marx generator
A Marx generator is a type of electrical circuit whose purpose is to generate a high-voltage pulse by a number of capacitors that are charged in parallel and then connected in series by spark gap switches. A Marx generator is a type of electrical circuit first described by Erwin Otto Marx in 1924 whose purpose […]
under voltage protection
Undervoltage occurs when the average voltage of a three-phase power system drops below intended levels, and is sometimes referred to as a brown-out. Electromechanical devices, including three phase motors and pumps, are designed to be operated at very specific voltage levels. If these devices are allowed to operate at reduced voltage levels they will draw […]
over voltage protection
Over voltage protection is a power supply feature which shuts down the supply, or clamps the output, when the voltage exceeds a preset level. Most power supplies use an over-voltage protection circuit to prevent damage to the electronic components. over voltage protection 2021 Design thinking for innovation in 3D VR Over Voltage Protection with Memristorfree […]
ULTRASONIC RADAR
Ultrasonic Radar Model Using Microcontroller ATmega128 Air traffic control uses radars to track aircrafts on the ground and in the air, and to guide planes for smooth landings. Police use radars to detect the speed of passing vehicles. Geologists use radars to map the Earth and other planets. Ultrasonic , electric and radar measurements for […]
timer circuit
A 555 timer can be used to create a basic schmitt trigger which converts a noisy input into a clean digital output. The input signal should be connected through a series capacitor which then connects to the trigger and threshold pins. A resistor divider, from VCC to GND, is connected to the previous tied pins. […]
Four Quadrant DC Motor Control
IEEE PROJECT Four Quadrant Operation of Chopper Fed Separately Excited DC Motor by Decoupled PWM Control Using Digital Signal Processorfree download DC Motors are used extensively in adjustable speed drives and position control applications. This paper proposes a method to control the speed and direction control of a DC motor by using a four quadrant […]
