Background
Back in April 2021, I was curious about how the room temperature and humidity will be like when the air conditioner is on or off, or when I turn on the Evapolar evaCHILL, or even both. As such, I decided to look for a temperature and humidity sensor to be placed in the room.
There were various brands and models that meet the requirements, but in the end, I decided to go for the Xiaomi Mijia Bluetooth Temperature Humidity Sensor 2 LYWSD03MMC as the price is affordable.
The Stuff
The Xiaomi Mijia Bluetooth Temperature Humidity Sensor 2 LYWSD03MMC comes in white color and in a square shape with rounded edges. It is light and small in size that it fits into my palm easily. It comes with a CR2032 battery inside so there's no need to have batteries ready.
Here are some pictures that I have taken to show how the stuff looks like:
