- Nowadays there are many automations comes for Agriculture purpose but the prices are very higher. For minimizing the cost and using NOR logic function to bring a new innovative ideas to Agro automations like Automatic Plant Watering System by using a NOR logic gate Function.
- Basic Concept of Project:
- The inclusive NOR (Not-OR) gate has an output that is normally at logic level “1” and only goes “LOW” to logic level “0” when ANY of its inputs are at logic level “1”.
- The Logic NOR Gate is the reverse or “Complementary” form of the inclusive OR gate.
- The output of the NOR gate is connected to Base of TIP122 Darlington Power Transistor to drive a Mini Submersible Pump.
3. Procedure for Making Project:
- Connect the 2N3904 NPN Transistor(Q1 & Q2) collector pin to Vcc.
- Connect the Q1 & Q2 Emitter pin to GND.
- Connect the TIP122 Base to R3(10K) resistor.
- Connect the R3(10K) resistor to Vcc.
- Connect the Q3 emitter to water pump(-)terminal & Connect the water pump (+)terminal to Vcc.
- Connect the Q3 collector to GND.
- Connect the Q3 base to metal probe & connect the another metal probe to Vcc.
- Connect the Q2 base to R2 resistor & connect the R2 resistor to Vcc.
