![]() This paper describes the use of multiple Infrared sensors to reconstruct a shape by detecting any changes in sensor displacement when there is an obstacle placed in front of the sensor. ![]() PIC32 VIEW ON COOLTERM MANUALThe system will help to eliminate the cost and inefficiency of human interference associated with manual monitoring and controlling of pump, while maximizing the performance and life span of the electric water pump. The developed system is capable of powering a 1HP pump from the input voltage, which can deliver an output current up to 20A. This paper provided an improvement on existing water level controllers by its use of calibrated circuit to indicate the water level and use of DC instead of ac power, thereby eliminating risk of electrocution. A prototype of the proposed microcontroller based water pump controller was fabricated and tested. The control system from which water level of both tanks are observed with simultaneous water pump control is based on existing water level technology using the principle of ultrasound for level sensing. This paper developed a microcontroller based water pump controller aimed reducing water wastages and pump failures, due to not switching it off immediately when not needed. Serious problem faced by several cities of the World, with wastage during pumping and distribution identified as a culprit. The MBACWPMLI when tested turned ON or OFF the water pump at the preset minimum and maximum level and the required LEDs were also turned ON at the corresponding water level. The microcontroller also gives digital output to turn ON the water pump (when the water in the tank is at a preset minimum level of 0.27 metres) or turn OFF the water pump (when the water goes above the chosen maximum level of 0.05 metres). The MBACWPMLI uses ultrasonic sensor installed at the top of a tank to send and receive sound waves, and the time taken is converted to distance by the microcontroller to give corresponding digital outputs which turns ON LEDs that indicate the level of water in the storage tank. ![]() The MBACWPML I uses the reflection of sound (echo) to give the indication of water level in a storage tank and also the automatic control of the water pumping machine. In this paper a Microcontroller Based Automatic Control for Water Pumping Machine and Level Indicator (MBACWPMLI) has been designed, constructed and tested. Water scarcity is one of the major problems facing some cities of the world and wastage during transmission has been identified as a major problem. ![]()
