Used to measure the acceleration value of three-dimensional space, any form of motion can be displayed its acceleration value directly, and has vector property. For example, measurement the gravitational acceleration value in local, or changes of acceleration when people in motion.

For measuring the ambient temperature, especially for some experiments have huge effect that produced by temperature, can according the current temperature to adjust a right environment for the experiment. Furthermore, can also used to monitor the change of air temperature throughout the day.

The positioning function in GPS sensor, can find the georeferenced of experimental location, the error of positioning accuracy is no less than 2m, and can record the moving tracks of position. We also can use the GPS sensor to record different experimental location, to explore the differences of experiment in different area.

Voltage sensor is used to measure the electric potential difference at both ends of the electrical equipment or circuits, after the circuit of voltage sensor transfering the voltage it collects, then it can realize the measurement. The voltage sensor can be used in the DC circuit and low voltage AC circuit.

Current sensor is used to measure the current in circuit. When current is passing the sampling resistance, it will form a tiny electric potential difference at both ends of the resistance; after enlarging the circuit, it can be available to measure the current accurately in DC circuit or low voltage AC circuit.

Temperature sensor adopts the NTC electronic temperature sensing element, when the ambient temperature changes, the NTC resistance changes accordingly. Normally the temperature needs no zero calibration and with relatively higher stability; therefore, the temperature sensor is rather popular in the low-middle temperature measurements.

Light sensor uses the silicon photoelectric cell as the sensing element; it can convert the light intensity into a voltage signal, keeping a direct proportion. For the sensor, the effective light spectrum is in a range of 380nm and 730nm, it is an ideal intensity sensor for visible light.

Sound sensor not only can measure the strength of sound (dB) within two measuring ranges, but also be used to measure the wave form (mV) of sound directly. With a frequency response rate, so that the sound sensor can measure sound speed and catch sound’s wave form.

Heart rate sensor is an experiment device used to detect the heart rate of human body. Simple and safe operation, can real-time measure the human heart rate value.

Motion sensor is a sonar equipment emitting ultrasonic pulse, it receives signal through the reflection of object, and then measure the time T when the high frequency sound wave goes around between the object and sensor; in accordance with the speed of sound in air, i.e. V, it can calculate the distance between the object and the sensor, i.e.: d=V*T/2.
