Water heating panel /Ds18b20 Temp

#1 Post by maluko » 15 Nov 2015, 22:37

Hello guys
I ended my project to control the temperature of heating with underfloor heating through of water panels,
I will use 4 sensors DS18B20
- Sensor to see the temperature of the hot water that goes into home
- Sensor for the actual temperature of the water after leaving home
- Outdoor temperature
- Indoor temperature
After testing in bradboard , I decided move to the final version of my project, then started to build a board with the necessary components.

- 2 x 4k7
- DC 5V to3.3V convert
- Micro USB
- 8 pin female
- ScrewTerminals

And This will work with domoticz, off course.

Really nice :)
I'm working on something similar for my underfloor heating (and am planning to use the output of the sensors to start/stop my circulation pumps).

I am planning to use a node MCU dev kit to avoid having to do my own PCB.

Where did you find the plastic casing ? It looks good and I cannot find suitable ones for the moment.

Thanks for sharing your project.

I has bougt this case here:

but for nodemcu kit i think is a bit tie, so see the dimensions.

careful with output system, because it is unstable yet, the device sametimes reboot, i has tested with relay and happen.

Have a look here for a heating system in DMZ.
https://www.domoticz.com/forum/viewtopi ... it=heating

If the EASY ESP module looses connection the script will regain it settings and switch on or off the relay again depending on the needed situation of the thermostat setting.

If you are using NodeMCu and you have no solder skills then this breakout board might be handy :-).

hi guys

since the last project i was working to improve my floor heat control so i have done this:

i have change to a esp 12 because have more GPIO to play :), has add a jumpers to reset, Gpio0/gnd, and upgrade (have to put gnd and vcc by fti too only put RX/TX), add blue led when module are on, lcd to display the temperatures on local, and a switch to turn on/on the LCD (the switch is working by domoticz but i think better work like action control or logic level by esp easy but not implement, nobody tell me if we will get any day).

so this are the photos:
