Absolute Native Electronics W1209 50~100 Digital Temperature Controller Thermostat

Good product

I Used this chip as a part of my engineering project which involved temperature sensing,works as expected and has no problems operating and temperature sensing is accurate to a good degreee,oh and i got a chip in which the color of the LED was blue instead of a usual red:PROS:-the product is compact and can be fit suitably in your circuit arrangement if you're including it in a project- the connections are fairly simple and to get it to work is easy,you can take help from youtube videos to learn how to connect this.- the led light display is clear and you don't need too much effort to see the numbers despite the smaller size.CONS:-the sensitivity of the chip seems to be 0.4 degree in celcius scale because every time the temperature went down or up ,it only showed changes in decrements or increments of 0.4 degree celcius ,this might be a problem for someone looking for precision and accuracy of measurement.- the temperature measured by its sensor is slightly different to the actual one,again it's a problem with sensitivity and accuracy- it looks a bit fragile and should be handled with care.

This is a perfect thermostat and it is small and accurate .Once Iplaned to buy a thermosta and searched in amazon there whwre many result ranging from 300 to 2000 .And the cheapest one was this .But this was reviewed as a good oneAt the time of buying there was lots of confusion and many unanswerd qns in my mind .So for a buyer there are some things that he should consider before buying this one1.You should give an input of 12v dc and it should be more than 60mA to work good othewise the switch will not work properly2.using this thermostat u can control any type of current(220 v bulb or fan ) for that there is an input and output ports (k1,k0)3.for giving 12v current u should have a 12v adapter or buy one which is costly4.There is no users manual with this one yuo should learn to confugure by learning from youtubeThis was a great product for me and the delivery was quick I used this for my incubator

Good product. It should come with the manual how to use the product. I have to check the YouTube to do the setting. I have waisted almost one week to do the setting and was almost set to return the product finally when checked the YouTube and could do the setting. Product does not come with the cover. Plz provide the cover as this could damage the product..

I order two piece of thermostat. One is working and the other one is not working. The quality of the product is very bad. It's accuracy is very bad

Great product

Good working,gets the job done. accuracy is not perfect but ok.good for valve.

I bought this on the 24th of May 2020 for a DIY incubator. worked perfectly. used it continuously for more than 2 years. helped me hatch a lot of eggs. 100 percent recommended.the disadvantage that I'd like to point out; like many others, is that there is no instruction manual for setting up the controller. But one can follow the instructions in the product description itself.I saw a few reviews claiming that their product god damaged or blasted on connection. That's probably because they must have connected the 220v supply to the 12 v terminals.
