Noise Sensor

The RS-ZS-N01-* noise sensor is a high-precision sound measuring instrument that uses a high-sensitivity condenser microphone. The range is as high as 30dB~120dB, which meets daily measurement needs. There are two output modes: rs485 and analog (4-20ma, 0-5v, 0-10v). The installation is simple and the price is cheap.

  • Model: RS-ZS-N01-*
  • MOQ: 1 PCS
  • Delivery date: within 24 hours
  • Price: $44.1

About- Renke Noise Sensor

The shell of this noise sensor is made of high-density waterproof material, and the inside is sealed with a waterproof strip to protect the circuit board, so the moisture-proof effect is significant. It can be used for outdoor noise detection for a long time.

About- Renke Noise Sensor

Renke has three types of noise sensors: RS-ZS-*-* microphone noise sensor, RS-BYH-M outdoor noise sensor, and RS-ZS-*-FL long rod noise sensor. All three models can be used for long-term detection of indoor noise levels, or outdoor sound levels in the environment. Noise sensors can be widely used for industrial noise measurement of various machines, vehicles, ships, electrical appliances, etc., and can also be used for environmental noise, labor protection, and industrial hygiene measurement.

Frequently Asked Questions

What is noise detection?

Noise is a sound with irregular changes in the intensity of sound waves. Physiologically speaking, all sounds that hinder people’s normal rest, study and work, and sounds that interfere with the sounds that people want to hear. There are many sources of noise, such as the sound of cars on the street, the sound of talking in a quiet library, the sound of machinery on construction sites, and the excessively loud sound of neighboring TV sets. In the field of communications, the energy field that interferes with signal transmission is called noise. The source of this energy field can come from the internal system or the external environment.

How does noise monitoring work?

The noise sensor has a built-in condenser electret microphone that is sensitive to sound. The total electric charge of the electret remains unchanged. When the plate retreats under the pressure of sound waves, the capacitance decreases, and the voltage between the two poles of the capacitor will be inversely proportional. On the contrary, when the capacitance increases, the voltage between the two poles of the capacitor will decrease in inverse proportion. Then the voltage at both ends of the capacitor is taken out through the field effect with very high impedance, and the noise sensor is amplified at the same time, so that the voltage corresponding to the sound can be obtained.

What kind of noise is considered excessive?

The noise in residential areas should not exceed 50 decibels during the day and less than 45 decibels at night. If it exceeds this standard, it will cause harm to the human body.

What is a sound sensor?

A sound sensor is defined as a module that detects sound waves through its intensity and converting it to electrical signals.

How to view the data of the noise sensor?

The monitoring data can be uploaded to the free cloud platform provided by our company or the customer’s own platform, and the data can be viewed through a mobile phone or computer after logging in to the account.

Where can I download the noise sensor manual?
