Smart Farming with IOT project

*Keypad Access Security System Access is controlled via a digital keypad. After three consecutive incorrect password entries, the system triggers an alarm and temporarily locks for a predetermined duration. A '*' button can be used to cancel an entry in progress. Upon successful authentication, the door unlocks and remains open for an eight-second interval before automatically re-locking. *Automated Night Lighting System This system utilizes a light-dependent resistor (LDR) to detect ambient light levels. In low-light conditions, the Arduino microcontroller activates a relay, closing the circuit to supply power to a 12-volt LED lighting array. *Automated Pet Feeder The feeder employs a disk with three compartments, rotated by a 180-degree servo motor. An infrared (IR) sensor monitors for the presence of food. If the sensor does not detect food, the disk rotates continuously until the sensor is triggered, at which point the rotation ceases. Irrigation system if the soil moisture sensor doesn't detect wet soil. So the pump that driving by relay works for 3 seconds. Then it stops for 20 seconds and checks is a solstice dry since the pump works again. If not, nothing happens. * * Manual Gate Control System This subsystem provides a manual override for a farm gate. A single press of a push-button opens the gate, and a subsequent press initiates closure. * IoT Environmental Monitoring and Response System This integrated system consists of several sensors and actuators: * Gas Sensor: Detects hazardous gas concentrations and activates an exhaust fan until the gas level returns to a safe threshold. *   Flame Sensor: Triggers a local alarm upon fire detection. It also interfaces with a cloud platform (e.g., Blynk) to send an email alert to a pre-configured address and commands a window to open until the fire is extinguished. *   Humidity and Temperature Sensor: Continuously logs environmental data for monitoring purposes. *   Ultrasonic Sensor: Monitors water levels in a tank. When the tank is empty, the sensor activates a water pump, which runs until the tank is full, at which point the pump is deactivated.
