Voltage Wireless Sensor

Measuring range: 55 -110 dB(A)

Resolution: 0.1 dB(A)

Voltage Wireless Sensor



I. Working principle

The measurement voltage is directly detected through the terminal block, and then the standard voltage signal is output through the amplification and shaping circuit.

II. Specifications

Measuring range: ±100 mA, ±5 V.

III.Structure and function

  1. The sensor terminal comes with a 1.8-inch color LCD screen.
  2. The sensor terminal is equipped with 5 function buttons.The operation interface is simple and convenient.
  3. The sensor terminal supports high-speed USB data channel, which enables high speed transmission of the data from the terminal to other devices such as PC, tablet or mobile phone.
  4. The sensor terminal supportswireless communication with experimental terminals.
  5. The sensor terminal has a built-in removable batterywith a capacityof 1800mAh.
  6. The sensor terminal is designed with a hidden buckle sensor interface to support combined experiments with other sensors.
  7. The sensor terminal has designed a fixation spot to get itfixed on the iron frameconveniently and combined with traditional lab equipment for experiments.
  8. The sensor terminal supports the latest operating systems,such as iOS, Android, windows operating systems, etc.
  9. Software with permanent use in digital laboratories in Kazakh and Russian languages. Designed for practical and laboratory work in the physics module of the school curriculum.

IV.Typical applications

This voltage sensor is a regular voltage sensor and is only used to measure DC voltage in a circuit. Its typical applications are: capacitor charging and discharging and series and parallel, research on Ohm’s law, volt-ampere characteristics of conductors, etc.


This product is suitable for educational use only and is not suitable for industrial, medical, research, or commercial applications.

VI.Usage Tips

  1. The usage method is similar to the voltmeter. When using, the voltage sensor is connected in parallel in the circuit. If the red wire of the voltage sensor is connected to the high potential end of the circuit and the black wire is connected to the low potential end, the displayed value will be a positive number; if the connections are reversed. , the displayed value is a negative number.
  2. The voltage sensor must not be used beyond the range, otherwise it will be easily damaged!
