Hi all. I’m uncertain if I should make a new thread, or ask the question here, so apologies if I step on someones toes by making the wrong decision.
I’m asking in here, as my goal is exactly the title of this post:
“Monitor 1 Thermistor with 2 devices?”
There might be a billion tutorials around the web, but I’m not an Electronics person, so I might have used the wrong search patterns. I found this thread and a lot of articles on Arduino as well.
One input (10k) needs to go to 2 devices.
It is the original input value that should be presented to the two end devices. End devices must not know they are not talking to a standard 10k sensor.
Let’s take a typical use scenario:
-
I have installed 1x 10k temperature sensor into a radiator (PC-watercooling).
a. Example: http://www.xs-pc.com/temperature-sensors/g14-plug-with-10k-sensor-black-chrome
2. I want the temperature to be read out and displayed on a LCD display
a. Example: http://www.xs-pc.com/temperature-sensors/lcd-temperature-display-g14-plug-sensor
3. I also want the same temperature to be sent to a fan-controller in order to control fan speed based on water temperature.
a. Example: http://shop.aquacomputer.de/index.php?cPath=62_63_64
This scenario is not possible unless I install 2 sensors to get the same readout (1), which seems rather redundant. This would also be impossible in many cases, as there is not room for that many sensors in the radiators.
I need a device to receive the initial temperature (1) and then present the same temperature (or resistance) to two devices (2) and (3).
The end devices must not know they don’t get the result from a standard 10k temperature sensor (1). This is in order for compatibility with existing products: ie.: would not do if specialised LCD displays or fan-adapters were needed to make it work.
If we talked about a proxy-server, I would say it worked in transparent mode. Which means true plug and play where end devices are unaware of the in-the-middle device.
