Hi Guys,
Let me start of:
I am a total newbie, I have build like 1 kit 8channel remote relay with instructions given, they said is was not for beginners, but with instructions what is?
I don't understand a lot from the hardware side of things (software = ok I am developer).
I want to basically know:
I need to build a temperature switch (very cheap), that will:
1. Allow me to set the on / off temperatures.
2. I need to set the min temp to turn on the device.
3. I need to set the max temp to switch off the device.
I need to please have someone explain me on how to design this. I have done almost research for 7 days now and did not find anything (expect for someone selling something similar):
**broken link removed**
The problem is this device is for only heater or cooler, cannot control both at same time and their rated amps are very low...
I am looking for circuit diagrams for such a project. To give more details behind this.
The input voltage = 12V dc rated 1.3amps
I need the switch / relay to close (powering the device) when the device is between the min / max temp and to open (stop power) when the device is below the min or above the max.
I need the exact same 12V dc rated 1.3amps output.
Reason:
This is to turn on an LCD screen (in my car - carputer), but I can only do this in the min / max range. Sometimes the car stands in the sun and it takes about 2 minutes for car to cool down with airflow ect.
This will avoid the LCD from obtaining damage due to being turned on while to hot or too cold.
I have fans and everything hooked up, but only want to switch power to LCD if this is in the operating temp as indicated by manufacturer of LCD.
Thank you (and please remember I am a total newbie)...
I need to know which parts to buy and how they will fit into the circuit diagram, I have pcb board, I have soldering station, I have all the toys, just not the know how.
