Introduction The theory of the automatic gate is very simple, when the motor vehicle comes It sensed by the motion sensor which send signal to the main circuitry board which then allows the current to pass through to the gates motor causing the motor to run in forward direction and the gate open, then closing … Read more
PROBLEM STATEMENT Mantrac Tanzania Limited the recent available security electric fence does not show or identify the location of intruder when attacking the electrified fencing place. Since the surrounding area is large, the guard took a time to identify the location of intruder when happens. Also it operates through out the day in 24 hours … Read more
PROBLEM STATEMENT DIT teaching tower is the building comprises with more than 15 studying rooms(venues) there is lack of proper information about the free venue which leads lectures and students consume a lot of time searching for free venue rather than studying MAIN OBJECTIVE The main objective of this project is to design venue monitoring … Read more
BACKGROUND INFORMATION Manchila village is located at Serengeti Municipal in Mara Region. Majority of the people of Manchila village are pastoralists and farmers. Water supply to the village is from a reservoir(Dam). Water from this dam is used for domestic, livestock watering and Agricultural activities such as Irrigation. Sharing of water resource with livestock is … Read more
PROBLEM STATEMENT Katoro Rice Milling Machine is powered by TANESCO but it experiences under voltage. This problem is caused by heavy loads to machine(s) because of sharing distribution transformer, when one machine with heavy load draw much power it leads to under voltage to the rest machines and these causes the machines to be operated … Read more
PROBLEM STATEMENT The low power factor problem at Mtibwa Sugar Estate is caused by the use of inductive loads and the presence of harmonics produced by the non-linear loads in distribution power system. These harmonics significantly reduce the life of capacitor banks and cause low PF. This increases current flow, power losses increase in both … Read more
INTRODUCTION In synchronous generator, difference of the stator frequency and rotor frequency is slip. Slip is the output of generator, when the generator is under loaded or overloaded suddenly, the frequency fluctuation try to overcome the changes. If this fluctuation continues rising and falling the slip i.e. output of the generator is disturbed, consequence … Read more
DESCRIPTION INFORMATION These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external … Read more
Bridge Rectifier IC Pin out A bridge rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. AC = Alternating current (INPUT) DC+ = Positive direct current (OUTPUT) DC- = Negative direct current (OUTPUT)
