Outdoor Temperature Sensor

I got my first one at Wal Mart. Under $20. It is still working and batteries last about 2 years.

I have had a La Crosse unit for probably 10 years now and the batteries last at least 2 years. It has a couple of minor annoyances. The date display is set to Month, Day, Year, and can't be changed to the Day, Month, Year format which we use. When the batteries fail you've forgotten the resetting sequence so it's RTFM. The atomic clock signals from Colorado only occasionally reach here which is OK in winter but when we go to Daylight Saving Time. (or Summer Time) like we are now, there in no provision to set the time zone to +13 hours GMT. I have tried GMT-1 but the Date gets fouled up.

But apart from all that, it's all good.

I purchased two 3M brand AC100MB-AH models at Sam's several years ago. I have one in my 2nd floor office and one in my walkout basement game room. I only use one wireless transmitter mounted outside and set both the indoor units to read from the same wireless outdoor transmitter. About every 3 months, I have to replace the 3-AA batteries in each indoor unit, but the outdoor unit's batteries will last two years or more. I can always tell when I need to replace the indoor batteries because I'll see "- - . -" displayed for outdoor temperature. Here's a link to Sam's site with the clock/thermometer.

Are you using Lithium Batteries? Not only do they last much longer but are also not as negitively affected by temperture changes.

We have an acurite from lowes that gives 24 hr high and low temps plus atomic clock that sets its self also gives forcast, they are a little pricey but we love it. In the three years we hav had it never has needed batts. It also displays battery level, just checked it and batterys are still half full.

My unit is a la crosse and according to their website the battery in the outdoor unit should last about a year. So I suspect their is something wrong with the unit. I was tempted to try Lithium batteries which would be better, but didn't want to throw money away if that wasn't the problem.

I have another outdoor unit that I am not using, so maybe I will test it out to see if the batteries last longer.

I have a couple of solar yard lights and will have to check into it to see if I can get it to work with my outdoor unit.

If not, I think I will look at some of the recommendations here for a new unit.

Thanks
Wes

Assuming your batteries are AA or AAA, a set of Lithiums will run you under $10.00. If you go to any weather station forum the advice is always go with lithium.

i have a LA Crosse unit and only change batteries twice a year,even in sub zero weather.

I also have a Lacrosse unit and I just changed batteries last week. It been up on the porch for over 2 years. I had a WeatherChannel brand in Canada and a set of batteries would last at least a year even in the -40C temps up there. I dont think mine transmit continuously but about every 10 minutes it sends a signal because it took that long or longer for the house unit to pick up the signal when I changed the batteries. Yours must be sending constantly to burn batteries like you describe.

I gave up on the battery operated ones and use the old fashion stick on window thermometer. I got this one from Northern Tools. It needs no batteries and it is easy to read. just peal it off the package and place it on a clean window. This is a poor picture from the manufacturer but it is see-through.
