5 in 1 Humidity Sensor

  • Problem
  • Updated 2 months ago
Hi, my 5-in-1 humidity sensor suddenly seems stuck at 82% or higher. The temperature is accurate, but the humidity is always very high. I brought the 5-in-1 unit inside, removed batteries, disassembled and cleaned it, but no change. After being inside more than 12 hours the 5-in-1 unit reads 82% humidity while several other sensors next to it read around 45%.

The 5-in-1 unit model number is VN1TXCA1.

Hello Steve,

Please try the steps below. If this doesn't correct the issue please let us know.

You want the display and sensor to be at least 3 feet from electronics such as televisions, microwaves, computers & radios. Follow the battery guidelines below:

•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.

•Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.

•Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.

•Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.

•Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.

•Mixing different battery types (brands, old/new, etc.) is not recommended.

If you are following the battery guidelines perform the hard reset steps below:
1.Bring both the sensor and display unit indoors side by side.

2.Remove batteries from the sensor.

3.Remove batteries from the display unit and unplug the AC adapter (if applicable). Once this is done hold the reset button on the back of the display for about 10 seconds. You may need a paperclip or toothpick to press the reset button depending on what the model number is.

4.Wait 1 minute to ensure any remaining battery power is discharged from both units.

5.Change the A-B-C channel on both the display and sensor making sure they both match.

6.Reinstall batteries in outdoor sensor first.

7.Reinstall batteries in display unit second. Press the reset button for an additional 10 seconds. Go ahead and set the date and time once an outdoor signal is received.

8.Let the units sit within a couple feet of each other for 30 minutes when comparing for accuracy
* The display should receive the signal within several minutes.

9.After a connection has been established you may place the sensor outdoors.
*If the signal connection fails after the units are separated try a new or different location for the display unit, the sensor or both.

Hi Jennifer, thanks for your reply! I followed all the steps above, but it didn't seem to make any difference. The temperature still seems accurate, but the humidity reading is way off (still seems stuck at 82% or higher).

Is there anything I can do to get an accurate humidity reading?

Hello Steve,

How high is the sensor mounted? If you bring it inside and let it sit next to the display for 30 minutes are the humidity readings within 10% of the display? How long have you had the weather station for, and where was it purchased?

The sensor is mounted at the top of a fence, probably about six feet off the ground. When I followed the instructions for the reset (your previous post) the humidity inside was about 45% according to the display but the outdoor sensor (which was inside all night next to the display) was still reading about 80% after having done the reset the night before.

It's several years old -- it was a Christmas present so I'd need to double check where it was purchased, but I'm pretty sure my wife ordered it direct from AcuRite.

The humidity readings were always accurate before (for years). This problem started a week or two ago.

Is there a replaceable sensor within the 5-in-1, or do I need to replace the whole 5-in-1 unit?

Hello Steve,

Model VN1TXCA1 is not compatible with the replacement temperature and humidity board.  You will have to replace the entire outdoor sensor.  For your convenience,  I have provided a link below to the replacements we offer. Please let me know if you have any other questions. Thank you.
