Hey Guys,
First post so please be gentle with me, I only play with electronics so I am probably being exceptionally stupid..
I am trying to create a circuit to switch on and monitor a digital output from an outboard motor. I have three signals I can connect to:
+12v power (permanently on)
GND
a signal which is only active when the outboard is running and has an output of 12V 50% duty cycle and frequency of between 50-1000Hz
To save on power I wanted to detect and respond to the signal to then power up the circuit which would ultimately monitor the signal and send it via wifi (ESP8266) to the boats central PC.
I thought that I could use a resistor and capacitor (sort of low pass filter) to generate a voltage from the pulse signal (if i understand correctly think this will give me a voltage or around 6V) to operate an analog switch such as DG419, but on rereading the datasheet I think that my overall current draw is too much for that.
My next thought is towards a solid state relay with a 6V coil voltage, but after advice if there is a more straightforward or appropriate solution that I could deploy.
