## Description

Absolute Native Electronics W1209 50~100 Digital Temperature Controller Thermostat : desertcart.in: Industrial & Scientific

Review: Great - Good product
Review: Nice product for projects and stuff like that - 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.

## Questions & Answers

**Q: Hi all, i have 1 doubt in this module. how to connect the 220 volt to make it as an auto switch off/on 60w bulb to use it inside an incubator?**
A: you have to use a 12V adopter power supply for this heater control module and set the unit for heat control mode.The relay provided in this board acts like a simple switch (this switch is completely isolated from the control unit) to control the 230V AC bulb.  Hope this should help you to solve doubt.As the lamp goes on the temperature of the sensor will go high and then when it reaches the set point the lamp will go off.  Note: set the lower temperature point to  be below room temperature other wise it will not switch on.

**Q: Can i control my air cooler which has 160 watts power consumption and runs at 230ac, do i need a relay to control the air cooler**
A: The circuit already have a relay which can be used. Yes you can control your air cooler with this.

**Q: can i know the range of temp which it can sense??**
A: It is mainly for coolers. Range is Zero deg to max 60 deg

**Q: can i set the temperature between two values**
A: No. Only a maximum temp cut off

### ⭐⭐⭐⭐⭐ worth the money
*by G***R on 1 July 2020*

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.
