Octopus LM35 Analog Temperature Brick

The Octopus LM35 Analog Temperature Brick is a plug-and-play temperature sensor module based on the TI LM35D precision centigrade temperature sensor. The LM35 outputs a voltage linearly proportional to temperature (10 mV/°C), making it easy to read with any microcontroller's analog input — no calibration or complex interfacing required.

Part of the ElecFreaks Octopus series, it features a standard 3-pin connector for simple connection to Arduino, micro:bit, and other microcontroller boards.
