[my knowledge of circuits is pretty bad, but I am willing to read anything I need to on the allaboutcircuits textbook]
I am looking to buy this: RF receiver and Transmitter
The specs show this: Main Parameter of Receiver Modules:
Control Mode: L4: Latch Type(Key A open, Key B close and Vice vers)
Working Frequency: 315MHz
Working Voltage : DC5V
Working current : Less than or equal to3mA (5.0VDC)
Working principle : superregeneration
Encode chip: PT2272-L4 compatible
Response rate: >-105dBm ( 50hmic )
Pin Assignment:
-D0: Output 0
-D1: Output 1
-D2: Output 2
-D3: Output 3
-GND: Ground
-VT: Switching voltage
-VCC: Supply Voltage
The purpose of this transmitter/receiver will be to turn a solenoid on/off. I initially thought I needed a switch, but I don't think RF controlled switches exist...probably because that is what the receiver essentially is (I think?).
Anyways, the solenoid is a 12v push type. I haven't decided on one yet, but it will definitely be 12v so I can use 23As.
The questions are: How do I wire a circuit using that receiver to turn on the Solenoid, then stop supplying power to it?
During my reading, I found that since Solenoids are inductors, I should have a diode attached to the solenoid so current doesn't flow back and hurt my receiver. Is that true?
What does that Working Voltage/Current mean? Will it still work with a 12v power supply?
(Also, if anyone is knowledgable in Solenoids, I was trying to find a practical guide to give me an idea of what 1N of force would be like. Something like the tables that tell you 30dBa is a whispering conversation etc.)
