The Auto-flow procedure is an easy DIY computerized water sprinkler procedure .It is designed to instantly water vegetation in a backyard within the universal loved ones. the improvement consists of designing an automatic regulate valve that's at once attached to the water provide (in this situation the typical loved ones tap or tap).The keep an eye on approach could have a 555 timer digital circuitry connected to water inlets pipes to accomplish the timing keep an eye on. The method layout is designed to water the crops at unique periods hence permitting the occupants of the family to take care of their backyard even if now not at domestic. This household product incorporates a timing circuitry hooked up to a valve that enables the circulation of water from a tap to water the crops via a tube. the automatic water sprinkler approach during this undertaking was once termed “Auto-Flow” as its identify represents that the procedure is totally automatic to permit the to water vegetation in his or her backyard on the clients discretion

The tubing system will be approximately 6- 8 meters in length will be shown in the following pages which will be fitted with plastic inlets to allow water to sip through and water the plants. 3 Tubing System The tubing system will be fitted with small plastic inlets to allow water to drop on plants. The flexibility of the tubing system allows versatile watering. It can water plants along uneven grounds and different heights. 4 Valve The AC valve is connected to the timing circuitry that uses 555 timers.

2] Pin 6 (Threshold): This pin is connected to the input of the upper comparator (labeled C) and is used to reset the latch which causes the output to go low. The threshold pin is level sensitive which allows slow rate of change of the waveforms. The safest voltage range that can be applied to this pin is between V+ and ground. A DC current must also flow through the terminal from an external circuit. 1 micro amperes and will define the upper limit of the resistance allowable from pin 6 to V+.

When the transistor is turned on the pin 7 is effectively shorted to the ground. The timing capacitance is usually connected to the pin 7 and ground and is discharged when the transistor turns on. The output stage is identical in timing to the conduction state of this transistor. The transistor is on when the output is low (low resistance to ground) and off (high resistance to ground) when the output is high. The saturation voltage is typically below 100 mV for currents of 5 mA or less. Maximum collector current is internally limited by design.
