Wireless Bluetooth Temperature & Humidity Data Logger | Smart Thermometer

This wireless Bluetooth thermometer and hygrometer is a smart data logging solution for monitoring temperature and humidity in real time. Using Bluetooth connectivity, the device synchronises data with a mobile app, where users can view live readings, analyse historical trends, and generate clear temperature and humidity curves.

The built-in data logger records temperature and humidity automatically at fixed intervals, allowing users to export historical data in CSV format for sharing or record keeping. Configurable alarm thresholds provide visual and audible alerts when environmental conditions move outside the desired range, helping protect sensitive spaces, equipment, or personal comfort.

Designed with a compact, lightweight form factor, the device is small enough to be wall-mounted, hung on a hook, or placed discreetly in indoor environments. A high-stability MEMS digital sensor ensures accurate and responsive measurement with a fast refresh rate, making it suitable for everyday household monitoring and basic environmental tracking.
