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.
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 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 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.
