LM741 as Voltage Comparator Output Not Reaching 0V—Is Offset Needed?

Hi all, 
 
Has anybody worked with LM741 and used it for voltage comparison? I am trying to using LM741 to compare two voltages, and essentially then use this as a thermostat. 
The issue is that once V+ > V-. the output voltage is 1.3 -1.6 v, but not 0 volts. Do I need to add offset? I am only using the 5 pins atm.  
  
Any help on this, or a precise design for comparing the voltages will be highly appreciated. 
  
Thanks.

I think you need to provide a bit more information. What are you supply voltages? Do you have a decoupling capacitor. Have you looked at the output with a ‘scope. If you can’t provide a diagram could you please let us have the PIN numbers and their connections.
The 741 is a bipolar device . Are you using positive and negative voltages? As a comparator, the output should swing from the positive rail (actually about 2V below) to the negative rail (actually about 2V above it). With V+ > V- the output should be at the V+ level. It is conceivable that your output is oscillating giving an average voltage that looks erroneous. And you should never see 0v out in the comparator configuration (unless you have used supply voltage splitting technique)

Just google "741 as comparator".Like this

Also, one thing about using an op-amp as a comparator is that it's useful to add a large value resistor from the output to the + pin. This gives it a bit of hysteresis making it less likely to oscillate.

I think you have to give more data. What are you supply voltages? Do you have a decoupling capacitor. Have you taken a gander at the yield with a 'scope. On the off chance that you can't give a graph might you be able to satisfy given us a chance to have the Stick numbers and their associations.
The 741 is a bipolar gadget . Is it true that you are utilizing positive and negative voltages? As a comparator, the yield should swing from the positive rail (in reality about 2V beneath) to the negative rail (in reality about 2V above it). With V+ > V-the yield ought to be at the V+ level. It is possible that your yield is wavering giving a normal voltage that looks incorrect. Also, you ought to never observe 0v out in the comparator setup (except if you have utilized supply voltage part method)
