Review: I won't buy another brand - I bought this in 2021 for its ability to measure down to 1% RH. My use case is measuring RH in a dry box for FDM 3D printing filament, where low RH is critical for filament storage and usage. These sensors have performed flawlessly for the last 5 years, and I suspect will perform similarly well for years to come. Battery life on these things can easily be measured in years, I don't remember the last time I needed to change the batteries. Each one needs 2 batteries, the outdoor sensor needs AA, and the indoor needs AAA. The only VERY small thing I can find wrong with these two sensors is that it takes a while for the outdoor sensor to update the measurement on the indoor one, its probably at least a few minutes. But that is a nonissue for most people and the update rate directly effects battery life of the outdoor sensor, so most people won't care. What really pushed me to make this review was doing a tear down of the outdoor sensor and investigation of the components inside. The sensor for temperature and humidity is a Sensirion SHTC3, which is a fantastic sensor. They are calibrated against a standard which has a NIST traceable calibration. It is likely that you will never need to do a calibration yourself either, even after 10 years the humidity sensor will typically only drift by +/-2.5% and the temperature sensor by +/-0.36f. And from some limited testing after 5 years between the outdoor and indoor channel the RH measurement only differs by 2% and the temperature measurements are the same. Pricing wise, if you wanted to remake just the main electronics from one of these sensors (display, sensor, mcu, battery holder, and radio) it would cost more than the product as a whole. So its great value for money. Overall, if I need a countertop hygrometer/thermometer I wouldn't hesitate to buy a Smartro product and I would recommend this product if anyone else needs one for their dry box. Review: Good product for money, but no WiFi connectivity for remote monitoring - The strengths: This digital thermometer is inexpensive, conveniently sized and the installation straightforward and easy. By cross-checking with my old-fashioned liquid thermometer, it also appears to be very accurate and did not require further calibration out of the box. The Bluetooth connection to the remote sensor paired easily and works well despite building wall barriers. MIA: WiFi connection to allow remote monitoring of temperature and humidity. ## Features - The Best Accuracy in All Conditions: SC92 wireless thermometer built-in world-leading Swiss sensor, shows subtle humidity and temperature changes. Arctic cold, scorching heat or jungle humidity: Unmatched temp ranges, humidity tolerance and update speeds mean readings can always be within 0.5℉ and 2% RH. It comes pre-calibrated for accurate measurement, and can be manually calibrated to improve data accuracy when it was impacted by other factor. - Connect up to 3 Wireless Sensors: Monitor your whole home, storeroom or greenhouse confidently with the hygrometer's wireless transmission capability. Add more sensors (only one included) and the digital thermometer can be connected to display readings from 4 places up to 200ft apart. - Comprehensive Temperature Tracking: The room thermometer tells you the highest and lowest inside and outside temperatures or humidity from the previous 24 hours or all time. Assess historical changes and refer to the Comfort Indicator to quickly see if they are deviating from ideal levels. - Easy-to-Read Backlit Display: Temperature and humidity monitor with 3.5-inch HD LCD screen(LxW: 3.4''* 3.4''). A simple touch on the top to turn on backlit. Clear and power-saving, reading more easily under weak backlit. Reliable operating buttons on the back for manual setting or °F/°C switching. Note: The backlit in the pictures is all in ON state. The backlit is not always on. - Built for Anywhere: The SC92 humidity monitor, with its retractable stand, magnets and wall-mount, can be adapted for any placement almost anywhere. It can be put in the baby’s room, closet, incubator, greenhouse, garden, nursery, wine cellar, office, basement or critter terrarium: No corner is too dark or awkward. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YXZ5N7M | | Additional Features | Temperature and humidity display | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #64,292 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #29 in Weather Hygrometers | | Brand | SMARTRO | | Brand Name | SMARTRO | | Connectivity Technology | Wireless | | Customer Reviews | 4.3 out of 5 stars 3,444 Reviews | | Display Type | Digital | | Included Components | manual | | Indoor Outdoor Usage | Indoor, Outdoor | | Item Length | 3.4 Inches | | Manufacturer | SMARTRO | | Model | SC92 | | Model Name | SC92 | | Number of Batteries | 2 AAA batteries required. | | Outer Material | Plastic | | Part Number | Z-001 | | Power Source | Battery Powered | | Product Care Instructions | Do Not Soak, Wipe Clean | | Resolution | 0.5 degrees fahrenheit | | Response Time | 10 seconds | | Reusability | Rechargeable | | Special Feature | Temperature and humidity display | | Style Name | Garden | | Unit Count | 1.0 Count | | Upper Temperature Range | 158 Degrees Fahrenheit | | Warranty Description | 13-month warranty except for artificial damages | ## Product Details - **Age Range (Description):** Adult - **Brand:** SMARTRO - **Connectivity Technology:** Wireless - **Display Type:** Digital - **Included Components:** manual - **Outer Material:** Plastic - **Power Source:** Battery Powered - **Product Care Instructions:** Do Not Soak, Wipe Clean - **Special Feature:** Temperature and humidity display - **Unit Count:** 1.0 Count ## Images ![SC92 Professional Indoor Outdoor Thermometer Wireless Digital Hygrometer Room Humidity Gauge Temperature and Humidity Meter Pro Accuracy Calibration - Image 1](https://m.media-amazon.com/images/I/619BDEIVHhS.jpg) ## Questions & Answers **Q: The display is so dim it is barely readable. can this be adjusted, or do i need to send it back? i'd really like to hear from the seller. thank you.** A: You could try a new pair of batteries to see if that works. However if not, please contact our customer support at:support@smartro.co with the picture of the screen and let's see if there is a problem on it. Thanks! **Q: What does it mean when the outdoor temperature starts to flash on the indoor display?** A: Mine just started doing exact same thing 10/17/22 should not be low battery as there is a icon located just under the Sensor # for that. **Q: Where can you purchase additional wireless sensors for this humidity monitor?** A: the referenced page states that it does not work with the sc92. Please fix **Q: Can the backlit display be set to remain on ?** A: The black and off-white display is always on. The color display is enabled by touching the button on top of the display and it goes off automatically after 9-10 seconds ## Customer Reviews ### ⭐⭐⭐⭐⭐ I won't buy another brand *by M***N on April 3, 2026* I bought this in 2021 for its ability to measure down to 1% RH.

By cross-checking with my old-fashioned liquid thermometer, it also appears to be very accurate and did not require further calibration out of the box. The Bluetooth connection to the remote sensor paired easily and works well despite building wall barriers.

I did so, and now the setup is working fine. I still think the setup procedure is somewhat awkward, and could be better explained in user guide. After getting it setup, though, it is easy to use and provides clear, well organized displays. This, plus the vendor support get a rating upgrade to 4 stars. ----------------------- ORIGINAL - If it worked as advertised I would give it only a 3, since the design of the transmitter is quite poor. A tiny channel selection switch inside the the transmitter is supposed to select a communication channel (1,2,3). My unit came with the switch set to 2, and I could not switch it to a different channel. Could be defective switch. Anyway I have no problem with using channel 2. When I followed the Rube Goldberg setup procedure with transmitter and receiver next to each other, I got an "outdoor" reading. But when I placed the transmitter outdoors (30 ft away) the outdoor reading went blank and has stayed that way. The display unit is easy to read (bright, good contrast). If only it had something useful to display... ## Frequently Bought Together - SMARTRO SC92 Professional Indoor Outdoor Thermometer Wireless Digital Hygrometer Room Humidity Gauge Temperature and Humidity Meter Pro Accuracy Calibration - SMARTRO SC42 Professional Digital Hygrometer Indoor Thermometer Room Humidity Gauge Pro Accuracy Calibration - SMARTRO SC91 Projection Alarm Clock for Bedrooms with Weather Station, Wireless Indoor Outdoor Thermometer, Temperature Humidity Monitor Gauge Hygrometer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/220560170-sc92-professional-indoor-outdoor-thermometer-wireless-digital-hygrometer-room-humidity](https://www.desertcart.vn/products/220560170-sc92-professional-indoor-outdoor-thermometer-wireless-digital-hygrometer-room-humidity) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
