Sensor module

Linear temperature sensor

Module 34 in the 37-in-1 kit. Measures temperature with a linear output. It works well as a first experiment before combining sensors into a larger build.

Concept

Linear sensors produce a predictable voltage change with temperature.

Try first

Read the value and compare it with room changes.

This is the quickest way to see the module reading change.

Connect ground, power, and signal according to the labelled pins and the source guide.

Upload a simple sketch or use a simulator to print the reading in the serial monitor.

Change the physical condition the module senses and watch the reading or output respond.

Build next

Graph temperature trend over time.

Turn the raw reading into a small useful interaction.

Add the OLED display when the reading is stable.

Use an LED, buzzer, servo, or motor only after the sensor input works by itself.

Write down the value range you see so your thresholds match the real room and module.
