The livestock that Sanjaya Farm sells are cows, one of the treatments carried out at Sanjaya Farm is offering drinks. Gives a long time because they always have to control the air level with each other, and have to turn on the water pump and drain it to the reservoir. Sanjaya Farm has a large area of ​​land because of the large number of cows raised. Hence the factor The security implemented at Sanjaya Farm is very careful in its supervision, only by locking the gate so that no one else is or a cow that can come out. The number of people who go out through the gate to know the security at Sanjaya Farm is not completely safe because they can't unites who goes in and out of the zoo. To solve the problem, the researchers created a safety and drinking system for cows based on esp32cam. For security systems using ESP32CAM, infrared as a sensor reader when the gate is open then the sensor will send data to the microcontroller to instruct the ESP32CAM to take an image and then send it to the database. System of offering drink using a water level sensor to read the water level, water pump as an actuator. The way this drink works is the water level the sensor will read the air level, if the altitude is below the minimum limit, the water pump will turn on to fill the air up to the maximum limit.
