2020-04-22 Source: admin
Brand: Shinyei model: pd4ns / pd42ns / ppd42nj type: dust production process: integrated output signal: digital type
 
Purpose:
Air purifier, air conditioner, ventilator, environmental monitoring, etc

Specifications:

Input voltage: DC5V
Current consumption: less than 90mA
Working temperature: - 10 ℃ - 45 ℃
Working humidity: less than 95% RH
Storage temperature: - 30 ℃ - 60 ℃
Particle diameter: more than 1 μ M
Output mode: PWM
Response time: less than 1 minute

characteristic:
1. Based on the principle of particle counter, the absolute number of particles in unit volume is detected

2. From cigarette smoke particles to pollen and house dust, particles above 1 μ M can be detected with high sensitivity and stability

3. Small size, light weight and convenient installation

W59 * h45 * D22 (mm), weight: 30g

4. Built in air flow generator can automatically attract the external atmosphere

5. Simple maintenance can be carried out to maintain the characteristics of air quality sensor for a long time

Application of air quality sensor
1. This product is made for the purpose of household appliances. For medical machines, disaster prevention machines, etc., Gao'an
Please do not use it when it is used for completeness, dependency, etc.

2. Installation:
① Since the air quality sensor of this product uses Joule heating of resistance, it will produce upward air flow inside the shell, so please use vertical
Using the posture of.

② Keep away from artificial air flow, such as fan. If it is used in air purifier, the front and rear of fan can not be installed. You can choose one side of the shell to install, but the air vent should be reserved on the shell to ensure that the external air flow can flow in;

③ Attention should be paid to avoid sticky particles such as oil entering the module during installation. When such particles stick to the optical components, faults will occur.

④ When the module is damp, its normal function will be affected, so it should be avoided.
3. If the updraft inside the housing is disordered, it will affect the characteristics of the sensor. Please consider eliminating the air pressure around the sensor.

4. This product uses plastic lens, which is cleaned once every 6 months. When cleaning the lens surface, please do not use organic solvent or detergent, please do not scratch the lens surface with hard objects. For the cleaning of lens surface, you can wipe it with cotton stick dipped in clean water, and then wipe it with dry cotton stick.


5. The adjustment and inspection of this product are carried out with the lens window covered. Please prepare the shading cover that can cover the lens window when using.


6. When the power supply of the product is in the plug-in position, the pulse voltage is controlled below 30mV.

In particular, when the dynamic lighting mode is used to control the LED for display, when considering the wiring route, the pulse supplied by the product should not exceed 30mV.
