Acu-Rite Sensors

NOTES: These are descriptions of a sensor units. A Sensor unit requires at least one receiver inside your house/office to be useful. The current models of Acu-Rite sensor units may be purchased separately on their website. Most sensor units may also be purchased in a bundle with a display receiver unit and sometimes even a bridge.

Any of the Acu-Rite sensor units may be setup with multiple receivers. IE: You could purchase a sensor unit and configure 2 or more display receivers to display the data it is sending. You could also add a bridge. Even though you are not limited to the number of receivers you can add, Acu-Rite DOES have a limit on the number of sensor units. There can be no more than 3 Acu-Rite sensor units within 200 feet of your receivers.

Please keep in mind that these are precision instruments. Like any delicate instrument, these should be handled and maintained with great care. This is true for an Acu-Rite sensor unit... or ANY OTHER BRAND's sensor unit. If you treat these well, maintain them, and are gentle when installing and maintaining them, these units should last for many years... barring of course mother nature throwing a tree at them or something.

I only use these units. I supply this information for your consideration if you purchase something from someone other than me. I DO NOT SELL ANYTHING.

The Acu-Rite 5-in-1 Sensor

Acu-Rite 5-in 1 PWS

My Weather Station's
Main Sensor Unit

This is a 5-in-1 Acu-Rite sensor unit. This is the main sensor unit for my weather station. The gauges and graphs I display on this website are, for the most part, generated from the data this unit supplies. This unit has 5 sensors, these are: temperature, wind speed, wind direction, rainfall and humidity. This sensor sends its data wirelessly to an indoor receiver. It has a solar panel that powers a fan inside the unit. The fan helps keep the temperature sensor accurate while the sun strikes the sun shield. It is my opinion that this is a well built, well designed, dependable, accurate and a well priced unit.

You will notice I raised it up a few feet above the 6' fence. I have also added a large squirrel baffle on the PVC pipe. The squirrel baffle is not to protect the sensor from squirrels, it is there to deflect wind that the fence forces to flow upward. Prior to this modification, wind would be caught by the fence and forced up and spin the wind vane on my sensor like a top. Since I installed the baffle the wind direction sensor is much-much more stable. I used PVC pipe to raise the sensor up as it is non conductive. The last thing I wanted was to turn my weather sensor into a lightning rod!! If you put up your own sensors, please keep lightning in mind.

Other than the fence, this sensor is as far out in the open as I can get it. I have a long narrow lot and it is probably 30 feet or more away from any structures/large trees. The trees you see in the background are really quite a distance away (150 feet or more?).

Using this sensor unit, the PC-Connect display unit described below and the Weather Display software described in the PWS Software section of this site, I am able to Rapidfire my sensor's results to Weather Underground and Weather Bug every 3 seconds.

Maintenance on this unit is fairly simple. Every 6 months I put in new batteries, clean the rain debris trap, wipe the solar panel and I ensure the unit is still level. There is a bubble level built into the top of the unit to make leveling an easy task.

If you decide to start a weather station, no matter what brand you buy, keep this in mind; you must place your sensor as high as practically possible, and as far away from structures as possible. Keep in mind your maintenance. If you put it in a place that is hard to reach or up higher than you can properly maintain, your sensors accuracy will eventually suffer and it may not work very long.

The Acu-Rite 3-in-1 Sensor

Acu-Rite 3-in 1 PWS

My Original Weather Station's
Sensor Unit

(and still going strong)

This is a 3-in-1 Acu-Rite sensor unit. This is the first sensor unit I purchased years ago. Readings from this are not used by this website, but it is online with Weather Underground. See the Helpful Links button at the top of this page to see this sensor unit's readings. This unit has run continuously since the day I purchased it and I have had no issues with it. This unit has 3 sensors, these are: temperature, wind speed and humidity. This sensor unit sends its data wirelessly to an indoor receiver. It is my opinion that this is a well built, well designed, dependable, accurate and a well priced starter unit. It lacks a few features of the 5-in-1, but it is a very good low priced unit if you want to start out simple like I did.

You will notice I also raised this unit up a few feet above the 6' fence. The reason for raising it up is just to get it as high as possible so wind speed is more accurate. I again used PVC pipe as I did with the 5-in-1 above as it is non conductive and less likely to attract lightning.

Maintenance on this unit is really simple. Every 6 months I put in new batteries and look it over for any possible issues.

Using this sensor unit, the Acu-Rite Bridge described below and the Kevin Key's Bridge Reader software described in the PWS Software section of this site, I am able to Rapidfire my sensor's results to Weather Underground and Weather Bug every 3 seconds.

The Acu-Rite Tower Sensor

Acu-Rite Tower Sensor Unit

An additional sensor

(Just because)

This is an Acu-Rite Tower Sensor Unit. This is a small sensor unit I purchased because I had a $10.00 credit at Acu-Rite and this was priced right. This unit has 2 sensors, these are: temperature and humidity. This unit sends its data wirelessly to an indoor receiver. It is weather resistant, but not weather proof. If you use this sensor outside, you must place it in an area that is protected from direct rainfall, like under an eve. I have it monitoring the temperature and humidity in my basement. It can be hung almost anywhere you want to monitor temperature and humidity; A garage, a wooden shed, an outdoor dog house, etc.

Maintenance on this unit is really simple. Every 6 months I put in new batteries and clean off any cob webs.
