About this model

The most compact version of the AAA battery holder for the Xiaomi temperature sensor LYWSD03MMC. Replaces the CR2032 battery with AAA batteries for greatly extended battery life. Uses metal battery terminals which are retained by the case, so some soldering is required. Add the wires as shown in the photos. Just pop the back off the sensor, remove the CR2032 battery and push it into place in the holder. The sensor's back is left unused. No supports needed when printing. Features a secure snap-in lid, and a press-fit sensor holder. The size of the battery terminals is 10 x 9 x 0.3 MM (Length x Width x Thickness). A photo of the terminals used is included in the pictures. These are the ones I used. Based on these battery holder models, but made more compact: 1. 2.
