i have been try to calculate the value of resistance need to use in this circuit and the value is 480 ohm . Correct me if im wrong, Voltage output sensor = 3.3v TTL Voltage base emitter = 0.9v for (Vbe sat) Ic = 100mA, Ib = 5mA --> i choose this as the relay will consume aroung 80mA = 0.7v for (Vbe sat) Ic = 10mA, Ib = 0.5mA Voltage collector emitter = 0.2v (typical) As for the formula to find R at base is R= (V - Vbe) / Ib R= (3.3 - 0.9) / 0.005 R= 480 ohm and all circuit diagram i found is using 1k ohm and 220 ohm for bc547 and 2n2222 respectively. Base on my calculation, if Ib is 5mA then the resistance is 480 ohm, but if i use 1k ohm, doesnt it make it Ib to 2.4mA and Ic around 50mA. That will half the potential of bc547 as it maximum Ic is 100mA. and one more thing is if the amp need to use in relay is 80mA, how can with Ic = 50mA support it.

hello sir after watching your video I thought if I can use a PIR sensor instead of an ultrasonic sensor in obstacle avoiding car will it work or it will keep crasing

No it will not work, it needs infrared radiation which will not be always there with obstacles

Can i put the sensor on tree . Bats are destroying the fruits . Can i connect the pir sensor to sound alarm system. Where can i buy this sensor . I have many trees . Bats fly away when sound is emitted. Is this waterproof. It rains a lot here.

Will this only detect the motion of a human or can it also detect moving objects that don't emit IR?
