Description

Here is a jolly cute, palm-sized, Bluetooth-enabled sensor to monitor your room's temperature and humidity. Only 43mm x 43mm, we dig its small form factor and minimal design. 

The shell is made of durable ABS material. Up front you get a 1.5" (28x28mm) LCD display. These sensors are sold to work with the Mijia "Mi Home" App (iOS and Android) and are a low cost way to add environmental sensing up to about 10 meters away.

And while it's totally fine to use it with the Mi app, we like this more for its use cases in general home automation and sensing projects!

The sensor has two modes. One is advertising modes, where it sends out sensor data every few minutes. The advertisements are encrypted so not easy to read. You can also connect to it as a BLE device and read from the sensor characteristic, which thankfully is not encrypted. You can use this with our library library for the LYWSD03MMC that works with CircuitPython. Or you can also hack it to add your own custom firmware to remove the encryption on advertisements. You can also use these with ESPHome / Home Assistant by extracting the binding key.

Comes with 1 x CR2032 coin cell battery and a back adhesive sticker, so you can mount the sensor anywhere you please.

  • Temperature range: 0ºC - 60ºC
  • Humidity range: 0% - 99% RH

Product Dimensions: 43.0mm x 43.0mm x 12.5mm / 1.7" x 1.7" x 0.5"

Product Weight: 21.0g / 0.7oz
