Description

Output: Analog Sensor
Type: Vacuum Sensor
Material: Metal
Usage: Level Sensor
Theory: Optical Sensor
is_customized: Yes
overview
The SDS011 using the laser dispersion principle, can obtain the concentration of particles between 0.3 to 10m in the air. with digital output and built-in fan is stable and reliable.
features
1. Accurate and Reliable: laser detection, stable, good consistency;
2. Quick response: response time is less than 10 seconds when scene changes;
3. Easy integration: output UART (or output IO can be customized), built-in fan;
4. High resolution: resolution of 0.3 g / m3.
scope
PM2.5 detector; Purifier.
Operating principle
The use of laser dispersion principle:
Light scattering can be induced when they pass through the particle detection area. the scattered light is transformed into electrical signals and these signals are amplified and processed. The number and diameter of the particles can be obtained by analysis because the waveform signal has certain relationships with the diameter particles.
Technical parameters
about the service life < br /> Lifespan is the key parameter of laser powder sensor. The laser diode of this sensor has high quality and its useful life is up to 8000 hours. If you need the data in real time (such as detector), you can use the default setting which measures at the frequency of 1 times per second. Because of the demand in real time is not very high (such as filter, air quality monitoring, etc.), you can use the discontinuous work method to prolong the service life. For example, you can start the sensor for 30 seconds per minute. If you have any other requirement, please contact us,
