Introduction

LM35 Linear Temperature Sensor is based on semiconductor LM35 temperature sensor. It can be used to detect ambient air temperature. This sensor offers a functional range among 0 degree Celsius to 100 degree Celsius. Sensitivity is 10mV per degree Celsius. The output voltage is proportional to the temperature.

Special Note:
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module.ks0123 (6)ks0123 (7)

Extension Experiment 1

Temperature Controlled Light
Complete the above experiment, you can get the analog temp. value. Want to try some different experiments.
For instance, when the temperature reaches the setting value, turn on an LED. Let’s get started right now!
Hookup Guide
Connect the EASY Plug LM35 sensor and LED module to control board using RJ11 cables.

Example Code

Below is an example code. Open or drag below code to Mixly Blocks and upload.

thumb

What You Should See
Done uploading the code, when the temperature detected by LM35 sensor is greater than 19℃, external LED will be turned on.

Little Knowledge:
As we all known, different regions might exists different climate. So if the setting temp. value is too low or too high, cannot turn on the LED, you can change the value in the code shown below.


Extension Experiment 2

Adding 4-digit LED Display
Next, how about adding a 4-digit LED display to show the temperature value. Let’s get started right now!
Hookup Guide
Connect the EASY Plug LM35 sensor and 4-digit LED module to control board using RJ11 cables.
