Key benefits Real time temperature and humidity indicators help you monitor ambient conditions and respond quickly. Low battery notification lets you know when charging is needed, preventing unexpected downtime. Simple charging with widely compatible microUSB connections ensures easy powerups without special cables. Clear charging guidance helps you reach a full, reliable charge for performance. Charging and setup When the low battery icon appears, recharge the device. Insert the included microUSB charging cable, or any compatible microUSB cable, into the device. Attach the other end to a USB DC charger that outputs 5V at at least 1000 mA (1 A) to ensure proper charging. Fully charge for at least 23 hours before first use. Do not charge using a USB port that only outputs 500 mA, as this may result in slower charging. Use scenarios Home environment monitoring: keep an eye on indoor temperature and humidity to maintain comfort and protect electronics, plants, or valuables. Office or classroom planning: monitor conditions in workspaces or study areas to support a productive environment. Small workspace or hobby setup: track environmental conditions in a workshop, craft space, or greenhouse to optimize outcomes.
