Adafruit Mijia Bluetooth® Temperature/Humidity Sensor with LCD Display

This palm-sized Bluetooth®-enabled sensor efficiently tracks your room's temperature and humidity. Compact at just 43mm by 43mm, it boasts a sleek design crafted from durable ABS material. The 1.5-inch LCD display effortlessly presents real-time data, suitable for easy viewing.

Seamlessly compatible with the Mijia "Mi Home" App for both iOS and Android, it serves as a cost-effective solution for environmental sensing within a 10-meter range. The sensor operates in two modes: an advertising mode that transmits encrypted sensor data every few minutes and a BLE device mode where sensor characteristics are accessible without encryption.

Perfect for home automation projects, the sensor pairs well with our CircuitPython library for LYWSD03MMC or can be customized with your own firmware. Integrate with ESPHome/Home Assistant by extracting the binding key. Versatile in placement, it includes a back adhesive sticker for convenient mounting. Note that a CR2032 battery is not included to facilitate air shipping; kindly purchase separately.
