1. Description

kidsbits blocks coding LM35 temperature sensor is fully compatible with kidsbits control board and Lego building blocks.

You can easily connect it to kidsbits control board for communication using an RJ11 cable without worrying about wrong connection and damage.

The LM35 temperature sensor is exactly what it sounds like – a sensor used to measure ambient temperature.

It is based on semiconductor LM35 temperature sensor. The output voltage of this sensor is linear with the Celsius temperature scale. The conversion formula is like: When 0℃, the output is 0V. For every 1℃increase, the output voltage is increased by 10mV.

It is effective in the range between 0 degree Celsius and 100 degree Celsius. Sensitivity is 10mV per degree Celsius.

2. Technical Parameters

  • Interface: EASY plug
  • Operating voltage: DC 5V
  • Output signal: analog signal

4. Import kidsbits library

Begin with the Mixly blocks coding, you should first import the corresponding kidsbits library for those sensor modules.

Connect the control board to your computer using a USB cable.

Then open the Mixly blocks software 0.998, set the board to UNO R3, select your correct COM port. On the upper right corner you can switch the language.

After that, click Import, import the keyes-kidsbits library. Shown below.

If import custom library successfully, you should see the sensor module library shown below.

Click on the display screen block of keyes_kidsbits, you can directly use the corresponding module.

5. Upload Code

Open the code folder we provided, or you are able to directly drag the code to Mixly window.

You can click the Code to check the C language.

6. Test Result

Hook it up and upload the code success, open the monitor and set the baud rate to 9600. It will display the current temperature value.
