Sensor module

DHT11 temperature and humidity module

Module 35 in the 37-in-1 kit. Reads temperature and humidity as digital data. It works well as a first experiment before combining sensors into a larger build.

Concept

Some sensors send structured digital readings instead of simple analog values.

Try first

Show temperature and humidity in serial output.

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

Build a room monitor with the OLED display.

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.
