Hi,

So I have a case like this:

I have Teltonika FMB204 and I have a sensor of light.

So when the sensor of light detects dark I want to turn on the LED diode.

I have one power supply of 5V which is supplying both LED diode and sensor.

And I have a separate power supply of 24v for Teltonika.

My question is: how to connect (wiring scheme) LED to the digital output of Teltonika? So I can send a signal with Teltonika to turn on the LED.

Thanks

Hello,

The only solution I see is that this scenario will be manged by your server and setdigout command.

Please specify what kind of light sensor do you use, what is voltage level on output when there is light detected and what is voltage level when light is not detected ? Does output voltage is digital (ON and OFF state) or it changes with light intensity ?

Hi,

I have a server and I have logic for automated sending commands through SMS.

So I had connected the light sensor with analog input from Teltonika in the range from 0-5V. (https://e-radionica.com/en/light-sensor-with-lm393.html)

In my office, the average voltage through the whole day is around half so 2.5V, and as soon as SUN is gone, the voltage rises above 3.5 (because of big windows), so I want to send it to Teltonika to turn on the LED.

Regarding LED I just want to turn on LED, so basically to put state of 1 (digital).

Thanks
