Review: A must have for monitoring wooden instruments! - Does it's job, nothing more, nothing less. I keep it in the guitar case to measure humidity, highly important for all-wood acoustic guitars, especially in the winter with household heat drying out the air. Review: Most accurate hygrometer - I checked the accuracy of this hygrometer using the Boveda calibration kit, and both of the hygrometers I purchased measured within 1 degree of the test kit. Other hygrometers I've used in my guitar cases were off by 5%. I have one of these in each of my guitar cases along with daddario humidipaks...a must have to protect the guitars from humidity changes. ## Features - The Planet Waves Humidity & Temperature Sensor is a precision-designed hygrometer that digitally indicates accurate relative humidity levels ranging from low (under 20%) to 99%.

I keep guitars, cellos, ukulele, etc. out (not in cases) in a humidified room. Not trusting any one hygrometer, I bought 4 different ones, among them the Planet Waves. All of them read (and continue to read) within 2% - 3% of each other. However the Planet Waves went through batteries at about (maybe) twice the rate of the other 3, so I stopped using it after a few months. I do not know if this problem is a unit design flaw, or restricted to only the one unit I happened to purchase. I have purchased other Planet Waves equipment and been happy with their stuff. This was my experience. Yours may be different. Again, this is a hygrometer, not a humidifier. If you are really seeking a humidifier, Planet Waves and a host of others make humidifiers for stringed instruments of various designs. **Q: What are the dimensions of this sensor? Can it be adhered to a golf cart with Velcro?** A: Approximately 3 1/2 inches by 2 1/2 inches. It could be adhered with velcro but being the owner of two of these hygrometers for use in my guitar room, I can attest that they can be up to 8% off. I suggest a humi-care available at cigar stores. It measures 1 1/2 inches in diameter and comes with velcro attachment. Much more accurate and can be calibrated. Not so with Planet Waves. Hope this helps. **Q: Does this have a clip on the back to attach it to the inside of the guitar case if you’re not laying it flat?** A: This hygrometer does not have a clip on the back. Try the Oasis OH-2+. It does come with a clip on the back.

I keep it in the guitar case to measure humidity, highly important for all-wood acoustic guitars, especially in the winter with household heat drying out the air. ### ⭐⭐⭐⭐⭐ Most accurate hygrometer *by D***E on March 17, 2025* I checked the accuracy of this hygrometer using the Boveda calibration kit, and both of the hygrometers I purchased measured within 1 degree of the test kit. Other hygrometers I've used in my guitar cases were off by 5%. I have one of these in each of my guitar cases along with daddario humidipaks...a must have to protect the guitars from humidity changes. ### ⭐ Low quality, does not work. *by S***R on September 12, 2015* I agree with the earlier review of djmic. There is a design flaw in the case/battery cover. The battery cover operates as the on/off switch. In order to turn the hygrometer on one lines up the two indicator "bumps". This brings a notch in the cover inline with the contact in the main part of the unit, unfortunately the On position is also the open position, when one turns the unit on, the battery cover is loose and the spring pushes the cover off and the battery out of the unit. It just does not work. I have no comment on accuracy. I have diligently tried to make it work including taping the battery cover in place; it's just not going to work, at all. I would NOT recommend this item to anyone. I would not purchase this item again. ## Frequently Bought Together - D'Addario Planet Waves Hygrometer - Humidity and Temperature Sensor - D'Addario Guitar Humidifier System - Humidipak Maintain Kit - Automatic Humidity Control System - Maintenance-Free, Two-Way Humidity Control System For Guitars - D'Addario Guitar Humidifier - Acoustic Guitar Soundhole Humidifier with Sponge - Non Drip - Suspends from Strings --- ## 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.pe/products/1415483-accessories-daddario-hygrometer-humidity-and-temperature-sensor](https://www.desertcart.pe/products/1415483-accessories-daddario-hygrometer-humidity-and-temperature-sensor) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-06-01*
