poopee_dogg asked How to drive 12 volt relay with 1.30 volt input?
I'm planning to remotely switch my lights using my cellphone. I will use the connection of the vibrator of the cellphone which outputs 1.30 volts to drive a relay. I know the basic diagram for a NPN transistor driving a relay. But I don't know what resistor and transistor to use. Thank you. Using 2N3904 transistor, what resistor should I use?
And got the following answer:
Simple. Amplify the 1.3 volts to 12V and voila! I would take the output of the cell phone's 1.3V and tie it to a 100 ohm resistor to the base of an 2n2222 transistor, which should be able to handle a small 12v relay. The emitter should be grounded, as well as the cell phone to a common ground, and the relay should go from the collector of the 2N2222 and then to 12-15V. That will do it! When the input goes to 1.3V, the transistor will turn on, pulling down the collector and provide current to the coils. There is a potential problem. The 1.3 v may not provide enough current to the base of the 2N2222. So you may have to tie directly to the base without the resistor. I would have to experiment.
The small 12v relay perform particularly properly with different applications which might be specific to power distribution and protection. The relays include wide adjustment ranges with a scale that is simple to read either in three or four digits based on the model. These small 12v relay assistance in growing the flexibility from the applications, reduce the overall energy and maintenance expenses. There are relays which are utilized for general purposes which are available in reputable styles with swift replacement options. And you will find models which are made use of for industrial applications and heavier duty applications that work on significant loads. These goods are produced to meet the lifetime industrial manage requirements on the applications.
Their most recent products will be the Time counter, Timer Delay, small 12v relay, Speedy Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and various other individuals. The site gives a detailed description of every model in several categories of small 12v relay couplings and sensors. These goods are very useful for high-risk applications. The small 12v relay are also offered with attributes like multiple timing ranges and functions.
