Model 01035 Replacement Humidity Sensor

  • Updated 2 years ago
So, the humidity sensor has lost its "senses" Heh, heh, heh...

For the past year I have noticed that the humidity sensor was becoming erratic and for the past several months the humidity has been either 1% or 99%.  OK, the problem is established.

I opened up the station and saw that the humidity sensor is a model VFC-1.  What an interesting sensor!  Humidity to Frequency!

This sensor has probably failed and needs to be replaced.  My question is where can I obtain one of these modules?  De-soldering and replacement is not a problem for me.

If AcuRite can sell or send me one that would be fantastic, but I doubt it.  (They look obsolete)
If a group member is aware of a legitimate source for one of these sensors that would be great too!

Cheers!

That's a very old 5n1.  They've been using the SHT21 chip since around 2012.  It's not compatible with your unit.

Last year someone found a source for them, but all the links they provided are now broken.

A very old 5n1...  I guess.  At my age very old is relative.  
Anyway, My wife and I purchased this 5n1 in mid-2011 at a Costco and I installed it late 2011 or so.

It has been running ever since!  I purchased the Hub later, it was a great addition to the 5n1!

Hi No_Spark,

We would recommend purchasing one of our new 5-in-1 sensors.  They now come equipped with a replaceable temperature and humidity board for instances where you are out of warranty and that were to happen.  A link to the sensor is below.  If you have any other questions, please let us know.  Have a great day!

Thanks for that suggestion Crystal, the cost of the 5n1's certainly are low enough!

But I like to repair things!  It is the right thing to do for the environment.

Recyle-Reuse-Reduce  Just buying a new one violates two of the three "R's" of the environment!

I am really not that much of an environmentalist but just purchasing a new one means I will throw away the old one adding to the landfill. My current 5n1 had a lifespan of about 3.75 years, I think I can get more life out of the product.  Otherwise this 5n1 cost me $60 per year to operate.  I think 10 or 15 years would be a good life so I could spend $500 to $750 on a new unit that would last longer.So,buying a new one it opens up the purchasing spectrum, I need to consider all the WU compatible stations.

It would be sooo much easier to purchase a $20 replacement part and keep on going!

Does anyone have a sensor replacement idea??

I was able to purchase a VFC-1 from a Korean source - removed old one and soldered in this one and humidity reads again.

I got my first 5 in 1 in the fall of 2010 at Lowe's as an end of year closeout.  In November 2012 I added the Internet Bridge.  In the spring of 2014 the Humidity Sensor and the Internet Bridge died.  Ended up getting a new 5 in 1 and Internet Bridge that same spring. Now it's October 2016 and the Humidity Sensor is dead on my 2nd 5 in 1.  I did see that there is a Replacement Temperature and Humidity Sensor for Compatible* 5-in-1 Sensors Model: 11197-VN1HSPCB for $10.  Unlucky me my 5 in 1 is not one of the compatible units.  If I was sure the replacement sensor would work I would get it and solder it in for $10 over buying a new 5 in 1 unit for $80.  If anyone has done this please let me know.  Thanks in advance.

It's been done.

If your 5n1 uses the SHT21 sensor, it should work.  I think they started using that chip in the 5n1 around 2012.
