Temperature Sensor

The Temperature Sensor can detect the temperature of water, a body, and other objects.

Before use, please assemble the temperature sensor probe and the block as shown above.


The frequency of sound waves that can be heard in the human ear is 20 to 20,000 Hz. Sound waves above 20,000 Hz are called ultrasonic waves. The sound waves are bounced when they encounter obstacles and are received by the probe of the ultrasonic sensor. Using the time difference from the transmission time to the reception time, we were able to calculate the distance between the ultrasonic probe and the obstacle.
