Simple Automatic Door Controller Circuit

More info here: www.homemade-c...
The video explains a simple automatic motorized door controller circuit, which can be used open a door with a press of a button, after which, subsequently, the door closes automatically and reverts to its initial position.
Parts List:
All resistors are 1/4 watt CFR.
R1, R9 = 1k
R3, R8 = 100k
R2, R4, R5, R6, R7 = 10k
Capacitors
C1 = 0.47uF
C2 = 2200uF / 25V (needs adjustment as explained in the above explanation)
Semiconductors
D1, D2, D3 = 1N4007
T1, T3 = BC547
T2 = 2N2907
T4 = TIP122
LED1 = Red LED 5mm 20 ma.
Relay#1 = 12V DPDT relay 40 amp contacts.
Relay#2 = 12V SPDT relay, 40 amp contacts.
Limit switches can be magnetic reed switches.
Push button can be any small push button

Hello sir Flame sensor is basically a safety device. Sir please make a simple circuit for LPG gas. I am giving the link in the page

@@mfarhan003 Ok, got it, but I think a smoke sensor will do the same job as the flame sensor, because the basic purpose is to detect fire. here's a smoke sensor and LPG senor video link, you asked for:

Hello, I saw the video but that is a smoke sensor which sensors LPG leakage. The flame sensor senses the flame of the ionization rod burner. Its benefit is that if the fire goes off due to any reason, it turns off the solenoid of the LPG gas line.

make a flame sensor ionization flame rod flame circuit?

I do not know much about this concept, therefore unable to make a video on this.
