12+ Rain Alarm Circuit Using Bc547. A bc547 transistor is a tiny three terminal device capable of converting small signal inputs a bc547 is a general purpose, small signal transistor fit for almost all types of circuit applications and therefore extensively used for making an. Working of the circuit is simple the transistor bc547b is working as a switch in this circuit when the water droplets fall on the sensor the transistor will become switched on and the 9v will start passing through the transistor.
This type we can make rain alarm circuit using npn transistor bc547. Bc547 is usually used for amplification and switching purposes. Bc 547 is an npn bipolar junction transistor that is used to amplify current to a certain level.
Hi, would you be kind to tell me if i can use two bc547 transistor to design a darlington pair amplifier?
12+ Rain Alarm Circuit Using Bc547. A rain sensor alarm circuit can be a very beneficial device for alerting when rainfall happens. We can use only one transistor…. Mostly it is used for the switching purpose as well as for amplification purposes. Working of the circuit is simple the transistor bc547b is working as a switch in this circuit when the water droplets fall on the sensor the transistor will become switched on and the 9v will start passing through the transistor.
