Accuracy Of 3-in-1 Sensor In Direct Sunlight

I am interested in purchasing a 3-in-1 weather station (model #00589), but have some concerns about the accuracy of the outside sensor if placed in direct sunlight. From what I understand the sensor has to be placed out in the open to get an accurate wind speed reading which means it must be placed in direct sunlight. I'm curious as to what everyone's experience is (who own the 3-in-1) regarding this issue.

Hi Ally,

The 3-in-1 sensor is vented and specifically designed to be in direct sunlight; you should see no inaccuracies in temperature, and the sensor is designed to be out in the open.  Here is some more info on the AcuRite 3-in-1 sensor:



3-in-1 Sensor Installation

3 Features Built into 1 Sensor  

Temperature, Humidity & Wind Speed 

Unlike regional weather predictions from sources like the news or online, AcuRite forecasting products rely on sensors that collect organic data right from your backyard. AcuRite's sensor based weather stations track specific sets of weather related variables, like changes in temperature, humidity, and barometric pressure to generate a forecast with pinpoint accuracy.

The AcuRite 3-in-1 sensor is designed to be easy to install and use, without compromising any of the professional weather tracking features you want.


 






Step-by-Step Installation Directions


STEP 1: Press the release lever and pull off sensor bottom for battery access.

STEP 2: Remove the battery cover and locate the A-B-C switch inside the battery compartment. Set the A-B-C switch to A, B or C. Be sure to choose the same channel that the A-B-C switch on the display is set to.

STEP 3: Insert 4 AA batteries into the sensor, following the polarity (+/-) diagram in the battery compartment. DO NOT use heavy duty or rechargeable batteries. Close the battery compartment cover. 

STEP 4: Secure your mounting pole into the ground or fasten the mounting base to a post or pole using the 4 longer screws included in the hardware bag. 

STEP 5: Place the sensor on top of the mounting pole or mounting base. Install at least 5 feet off the ground for more accurate wind measurement.

STEP 6: Secure the sensor onto the mounting pole or mounting bracket using screws and a screwdriver. 

STEP 7: Ensure the sensor is level. We recommend using a bubble level (not included).

Your 3-in-1 Sensor is now ready to use!

I too have the same issue. My system is brand new. I have another small system from accurite besides the 3 in 1 system. My small system has the sensor under the cover of my front porch. My 3 in 1 sensor is in the backyard. When it's overcast the systems show identical temperatures. When it's sunny the 3 in 1 sensor shows 6 to 10 degrees warmer. Should I try to build a small roof over the 3 in 1 sensor? I know this would affect wind speed for sure though. I have already reset the unit and tried a different channel.

yes i'm still having the issues so i changed my wunderground account to use my tower sensor instead. the problem with that however is that it limits the data sent to wunderground to temp, humidity, pressure. no wind or rainfall. my five in one always shows 5 to 10 degrees higher than the actual temp. i wish you had a fix for this otherwise good system

Hello Rob,

Please check to see if your aspirating fan is working.  To do this you will need to open the sensor and hold the top half in the sun.  The fan should start by itself when sun hits the solar panels on top.  Please let us know if you continue to have this issue.  Please call AcuRite Customer Support at 877-221-1252.  Thank you and have a great day!

I don't think that is true. The first day of use my 01604 the 3 in 1 sensor was reading 26*F and 78%RH at dawn. Within minutes of the sun rising above the tree tops the temperature soared to 42*F but there was still a hard frost on the roof 12' below and on the cars windshields. 2 days later I was in heavy dense fog the whole day with temperatures falling throughout the day. At sunset the display was reading 29*f and 99% RH. It wasn't until midday the next  day when the shined on the sensor and warmed it up to33* F and the RH dropped like a rock. What am I supposed to do? Mount the sensor on the north side of the house close to the ground and sacrifice wind speed,  or keep the sensor high and sacrifice temp and humidity? The unit has been in use for 5 days now.

Hello 1houndchaser,

You may wish to try a reset of your system and change to a different ABC switch setting; also, ensure you are using quality alkaline batteries in the sensor such as Rayovac or Energizer; avoid heavy duty and rechargeable batteries.  Let us know if we can be if further assistance.

I am having the same issue as 1houndchaser. How does the reset and the change of ABC setting produce a more accurate temperature reading in the Sun light?

Hi Ransomed,

The changing of the ABC setting does not itself produce a more accurate reading; in the event there is interference, changing this setting can help clear up the interference that may be causing errant readings. 

If the steps in this thread do not alleviate the malfunction, contact our Customer Support Center at 877-221-1252 for further assistance.
