Geevon Indoor Outdoor Thermometer Wireless with 3 Remote Sensors, Digital Hygrometer Indoor Thermometer, Temperature Humidity Monitor Gauge with 200FT/60M Range

I use these thermometers in my fifth wheel so I can keep track of the temperature and humidity in the closet, outdoors, in the bedroom, and the living room. For an inexpensive set, they are accurate, easy to set up, and easy to read. I put the outdoor one on one of the slide supports to keep it dry and protected. It's a good set.

I am pleased with the performance of the device as it has good range and reasonable accuracy. I have the main unit on the wall near my front door so I can see what is happening at a glance. I had no trouble getting readings from a unit in the attic, out back and in front and even one in a chest freezer in the garage. Other devices were unable to communicate from inside the freezer, but this one somehow is able to get through. As the batteries age, the display can get dimmer, so that tells you it it time to replace them. Seems to be about a year for the main unit, with similar for the remotes.

Bought two of them to have in the houses of my animals to watch the temp in the winter. They work good and are accurate however the one set will sometimes pick up the sensor of the same number of the other set. Was easy to set up and seems to be of good quality but I’ve only had them for a few months

I am using this product to monitor temperatures in the refrigerator and freezer sections of our main fridge, as well as a smaller fridge in the basement. For this application, it works great. No issues with the wireless connection to the remote sensors, even the one down in the basement fridge. The main display is easy to read at a glance. And while the individual remote sensors have their own displays, the digits are really small, and hard to read at a glance. Not a big deal to me though. As for accuracy, when I first unpacked the product, I set up the sensors side by side and let them adjust to the room's temperature for at least an hour, then compared the readings. Two of them were within 1 degree of each other, which I though was good, but the third sensor was off by a bit more than that. I wasn't super pleased about it, but the readings were close enough where I did not feel it was worth returning the product. The humidity readings were pretty close to one another as well. Considering the reasonable price and decent performance, I am pleased with this purchase and see no reason not to give the product a 5-star rating.

This unit, which cost noticeably less than other brands, exceeded my expectations. It measures the temperatures in 4 locations, 3 are remote, and one is at the display unit's location. In addition , it also measures the relative humidity at all 4 locations. the display is easy to read, and appears to be accurate. I would recommend it To my friends and relatives.

Keep one in my garage, one in my basement and one on each floor of the house. They are still using the original batteries and I have been using them for several months. They update every few minutes.

Works perfect! We keep a sensor in the garage, outside the house and in a spare bedroom that doesn’t get warm from our heater. It’s perfect for our purposes.

Display and blinking connection light on one of three the sensors stopped working after 7 months. This was a sensor that was outside. It was generally covered and out of the elements but outside nonetheless. The sensor still connects to the main unit but there is no indication on the sensor itself. Tried different batteries but display is still defective. *Update 2 (12/18/2025) - The defective sensor stopped working completely at 1 year. I opened it up and it had some corrosion on the battery terminals and where the wires are soldered to the board. I cleaned everything up and soldered two new wires to see if it would come back to life. It was dead. After opening it it doesn't look like it's designed for outdoor use. No seal. Other two sensors are still working but they have been used inside only. *Update - The seller contacted me after my review and offered a full refund. I accepted. They then reneged on it and ask for my address to sent a replacement unit. However, Amazon specifically says in the messages to not to give out personal information so I didn't. They are now offering a $7 refund for one of the sensors. This would be fine if they would have led with that. They contacted me first and offered a full refund, I never contacted them about the sensor. I just gave my review for the experience I've had with this unit. I'm not happy with their customer service. It's not about getting a full refund for something I'm still using. It's about them offering it in first place and then walking it back. Again, they contacted me with that offer.

While I haven't tested this for the claimed 60m range (Clear line of site), it is working faultlessly at 35 m from a cupboard in my garage, through plywood doors, across the garden, 90 degrees right through double glazed oak patio doors and across the kitchen. All are reading within half a degrees C of each other when all in exact same environment. Good accuracy and very consistent. Remember to allow a good long time for humidity to be detected well (true of all humidity testing, its never instant on any device). Love this product, and highly recommend it. Great price (29.99), no frills, just works great. (reviewed after 30 days). Super easy to use and reset MAX / Min temps individually.

Work very well. 2 in sheds - over 30 feet from base and always transmit good signal. Very pleased with purchase.

Es perfecto para el precio que tiene Las lecturas de los sensores son bastante precisas, aunque la unidad principal con la pantalla grande a veces se desvía un poco Además, se puede cambiar la temperatura de los sensores de Fahrenheit a Celsius: basta con quitar la tapa de las pilas y, a la izquierda del selector de canal, hay un pequeño orificio donde se puede introducir un alfiler y pulsar el botón Sería muy útil que esta información apareciera en el manual de instrucciones
