AcuRite Wireless Indoor Outdoor Temperature and Humidity Sensor (06002M) , white

Outside temp on my Indoor / Outdoor Thermometer was wonky. Worked sort of and often looked like the batteries were dying though they were new. So just planned to buy a new I/O Thermometer. Didnt find any I liked as much as the one I have. Then I found this sensor replacement. Outside temp & humidity are back with no issues. Hopefully good for another 5 years or so, and at about 1/4 the cost.

Had to replace my old sensor this one linked up good with my system and has been working great for a couple months. Would buy again.

Works perfectly but should have priced a new one first. Part cost almost as much as whole unit.

I put the batteries in and through the switch. It loaded quickly with the currant temperature. It works Great!

Works wonderful- it’s accurate and weatherproof

Purchased 4 units to monitor humidity in crawlspace and attic. 2 of the units are off by -6% in humidity 1 unit is off by -4% humidity 1 unit is off by -8% humidity I calibrated these using the salt/water 24 hour method and a total of 6 units. One of the units was a more expensive (50$ sensor) from another brand that swears by their accuracy and sure enough that was the one unit that got exactly 75% humidity after 24 hours. These...not so much. These are probably mass-produced and not given a second thought on calibration. Thankfully for my use case (home assistant) I can set an offset.

This replacement sensor connected easily to my inside unit and started right up. It saved me from having to purchase a whole complete system.

Finally, after 8 years of being out in New Jersey weather, the original unit failed. The inside wires from the circuit board corroded off, I believe because of the battery leaking. Purchased this one to replace the original one, and it is working perfectly. For some reason I needed to switch the default setting of C on the ABC switch to B, to get it to connect to the display unit. The failed unit was on C. Definitely recommend this replacement. A heck of a lot cheaper than purchasing a whole new setup.

Needed a replacement for my weather station. This worked as it should.

It replaced original, works perfectly
