I am going to use it to monitor my central heating unit.
I am going to place one MLX90614 just behind the pipe going to the radiators and one behind the warm water pipe.
I am also thinking of using it to monitor my wood stove. ;)
I have moved this from ESP Releases topic, so that that one stays clean.

I am also interested in practical applications of that sensor, compared to DS18B20, that is also available as waterproof probes and I have been planning to use this one on my pipes.

Why not with a DS18B20?
Just curious.

I am going to use the MLX90614 for three reasons:
1. I would like to experiment with the MLX90614 :)
2. I didn't know if the DS18B20 supported the temperature range, especially with the wood stove
3. I think IR measuring is reacting faster

Okay, thanks.

DESCRIPTION
The DS18B20 digital thermometer provides 9-bit
to 12-bit Celsius temperature measurements and
has an alarm function with nonvolatile user
programmable upper and lower trigger points.
he DS18B20 communicates over a 1-Wire bus
that by definition requires only one data line (and
ground) for communication with a central
microprocessor. It has an operating temperature
range of 55°C to +125°C and is accurate to
±0.5° C over the range of 10°C to +85°C. In
addition, the DS18B20 can derive power directly
from the data line (“parasite power”), eliminating
the need for an external power supply.

The wood stove ... that depends on the material it is made from.
Mine is made of stone and its temperature does not reach beyond 80 degrees.

IR is faster, but how fast do you want it to be? I think a small chip can easily follow the metal hot water pipes and radiators.
