I don't think I've changed the battery in several years. That is also true of the outdoor weather station as well. The battery lasts a very long time! I've put these in different rooms to monitor the temperature throughout the house. ## Frequently Bought Together - Ambient Weather WH31E Thermo-Hygrometer Sensor for WS-2902, WS-2000, WS-5000, WS-1965, WS-4000, WS-3000 and ObserverIP Series Weather Stations - Ambient Weather WH31L Lightning Detector for Models WS-2000, WS-5000 --- ## 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.hk/products/35825692-ambient-weather-wh31e-thermo-hygrometer-sensor](https://www.desertcart.hk/products/35825692-ambient-weather-wh31e-thermo-hygrometer-sensor) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-17*
