About this product
Stand it on a desk or fix it to a wall with the included adhesive tape: the Xiaomi BHR9041GL monitor shows temperature (0-60 °C, 0.1 °C resolution) and humidity (0-99% RH, 1% steps) on a 62.6 x 53.2 mm LCD that stays readable from across the room. Readings refresh roughly every 6 seconds, and the industrial-grade Sensirion sensor built in Switzerland keeps values steady in a bedroom, nursery, home office or wine store. It links over Bluetooth 5.0 Low Energy (BLE Mesh) to the Xiaomi Home (Mi Home) app; remote viewing and automations need a Xiaomi BLE Mesh gateway. A pre-installed CR2450 coin cell powers it for up to about 1.5 years. Shipped by CasaSmart in Chisinau with 24 months of official warranty.
