In the kit human sensed automatic door control in some area where we need only humans to enter, we can use this type of system. Here we have used PIR sensor to detect human beings. As a person is detected by the sensor, the gate gets opened for some time and then gets closed automatically. An alarm system is also there. The time between opening and closing of the system can be changed by user using a preset. For the demonstration of the gate we have used a DC motor controlled system which controls the gate.
This kit human sensed automatic door control can be further improved and cameras can be mounted, if someone comes, the camera can capture the image and store it. In case of surveillance also, this system can be used to save the power, the camera should start recording only when there is a movement, and otherwise it should go in standby mode.
In this kit human sensed automatic door control a PIR sensor is used to sense the presence of any human. As soon as the presence is sensed by microcontroller, it will control the gate by sending the signal to motor driver. The motor driver will drive the motor and hence the gate. The gate will be opened for some time and will automatically be closed. The opening and closing time can be changed by the user.
