The OBET Wireless Thermometer links three remote sensors to a color display that shows indoor and outdoor temperature, humidity, barometric pressure, and a 12 hour weather forecast. Sensors transmit up to 500 feet, so you can track a garage, barn, greenhouse, or outdoor spot from inside the house, and alerts sound when readings move past limits you set.
It fits homeowners, homesteaders, and small business owners who need wireless climate monitors across several locations. The display stays lit continuously when powered by USB, while on batteries the backlight turns off after 10 seconds.

Monitoring Freezers, Crawlspaces, Outbuildings, and Frost Risk From One Display
If you store meat in chest freezers out in the garage, keep feed or product in an outbuilding, or need to know when temperatures are heading toward freezing, this system puts those readings side by side on one screen. The frost icon starts blinking as the outdoor reading approaches 32°F, giving you a cue to cover tender plants with frost cloth or close up a backyard greenhouse before nightfall.
The 500 foot range reaches buildings set well back from the house, and the humidity alert can catch a damp crawlspace or storage room before moisture causes trouble. With the pressure based forecast on the same display, you can glance at it in the morning and plan field work, watering, or livestock chores around the next 12 hours of weather.
What to Expect from the OBET Wireless Thermometer in Real Use
Pairing is quick, often just powering on or pressing one button. Purchasers have held a connection at roughly 200 feet and report strong signal from crawlspaces and attics. The color display reads easily across a room, and the forecast was roughly 90% accurate for an early tester. Sensors sit in freezers, garages, attics, bedrooms, and climate controlled warehouse spaces, where a humidity alert prompted owners to run a dehumidifier before stored product was affected.
Before placing sensors, set them beside the base for an hour. A separate owner found readings varying 1 to 3 degrees, then assigned the least consistent sensor to the outdoor spot. The outdoor sensor needed new batteries after about six months through temperatures from 90°F to well below zero, while indoor sensors kept running.
There is no clock on the display, the large model is bigger than some expected, and labeling each channel helps you remember which storage building each sensor covers. The battery mode backlight timeout feels short, and the stand on the smaller model tips over easily.

Frequently Asked Questions
Can you put an OBET wireless sensor in a freezer?
Yes. You can place a sensor inside a chest or upright freezer to keep an eye on its temperature from the base display without opening the door. Set an alert at the temperature where you would want to take action, and confirm the signal comes through after the freezer door is closed, since metal walls can shorten range. Placing the base unit closer to the freezer helps if the signal is weak.
How long do the batteries last in OBET wireless sensors?
Battery life depends heavily on where the sensor lives. Sensors in heated or climate controlled spaces can run many months on a set of batteries, while a sensor outdoors through hot summers and subzero winters drains faster and may need new batteries after about six months. Cold weather is the main factor, so check the outdoor sensor first when a low battery warning appears.
Does the OBET weather station display the time?
No. The display shows temperature, humidity, barometric pressure, the weather forecast, and alerts, but it does not include a clock. If you want the time on the same shelf or wall, you will need a separate clock alongside it.
