Principle and Installation and Maintenance of Dust Sensor

Update: 2019-09-21 16:32 Source: LUFTMY Reading: ↻ News
 

Dust sensor detects dust content in air environment by light scattering. Then it is transformed into a sensor assembly with voltage output. Dust types that can be detected include cigarette smoke particles, bedding dust, cleaning dust, lice, pet hair, etc.

The degree of dust sensor can sense is:

1. about 10 square meters of space, placed in the state of cigarette 3 to 4 will trigger induction

2. about 10 square meters of space, smoking a root will trigger induction

3. if it is dust particles, shaking bedding can also sense particles

Uses of dust sensors:

1. Sensors for household products such as air fresheners, ventilators and air conditioners.

2. It can be used as an indoor environmental condition monitor in family, office and hospital waiting room.

Attentions for installation of dust sensor:

1. Because of the detection principle, there will be a weak updraft in the sensor, so there is a distinction between the upper and lower in the installation.

2. In addition, in order to avoid disturbing the internal air suction and exhaust outlet, strong wind should not be directly encountered.

LUFTMY LD15 is a high-precision particle concentration sensor based on the MIE scattering theory of laser. It can continuously collect and calculate the number of suspended particles of different particle sizes in the air per unit volume, namely the concentration distribution of particles, and then convert it into mass concentration and output it in the form of universal digital interface.The sensor can be embedded in a variety of instruments or environmental improvement equipment related to the concentration of suspended particles in the air to provide timely and accurate concentration data.
