Some unusual shape for an indoor sensor, I thought it might be nice in a kids bedroom.

Using RAKwireless WisBlock modules and LoRa communication it can measure temperature, humidity and air quality in your kids room.
Only 98 x 60 x 22 mm (w x l x h) small, with enough space for a RAK19003 Base Board, a WisBlock Core module and up to 2 sensor modules. Easy access to the USB port and space for a 1000mAh battery.

Supported WisBlock modules:

• RAK19003 WisBlock Base Board
• RAK3372 WisBlock Core Module STM32WLE5
