Dsm501B Dust Sensor For Air Quality Monitor

Dust sensor module dsm501b description Dust sensor module: dsm501 series detects the level of indoor airborne dust, particles, and pollen, and ideal for use in stand-alone air cleaner or iaq monitor. Pwm output of the sensor can be directly connected to î¼-com to control fan speed or ventilation and also to display the level of particles. Detectable size of particle is limited to minimum 0.7 um, and the application for smoke or fire alarm is prohibited. Dust sensor module dsm501b type: Dsm501a : 2mm pitch connector type (20010wr-05). Dsm501b : 2.5mm pitch connector type (s5b-eh). Dust sensor module dsm501b electrical characteristics: Supply voltage: dc510% Power consumption: 90ma Operating temperature range: -10~ +65'c Operating humidity range: 95%rh or less (without dew condensation) Recommend storage condition: -20 ~ +80'c Dimension: w59 * h45 * d20 (mm) Detectable particle size: approx. 1um (minimum) Detectable range of concentration: 0 - 1.4mg/m3 Output signal: pwm (pulse width modulation) Time for stabilization: 1 minute after power turned on Sensor characteristics: to be maintained in between the upper limit and lower limit of the standard dust sensor unit Dust sensor module dsm501b features: * pwm output * easy installation * single power supply * compact size and lightweight Dust sensor module dsm501b application: * ventilator etc * air conditioner * air quality monitor * air cleaner or air purifier

A single unit, based around a powerful 32-bit floating-point ARM microcontroller, designed to provide a complete analysis of local air quality. The unit deploys four electrochemical sensors, an NDIR CO2 sensor and a laser particle monitor. These combine with a temperature and relative humidity sensor, and GPS is used for accurate location and timestamping.There is also an optional microphone to provide ambient noise information. Data is stored locally and uploaded to a central management site. Specification accurate electrochemical cells (Alphasense A4) monitoring CO, NO, NO2 , and O3 down to ppb levels. Other gases can be sensed if required (eg SO2 ). digital NDIR CO2 sensor (Atmospheric Sensors/Alphasense or SenseAir). laser optical particle counter (Alphasense) to provide PM1, PM2.5 and PM10 readings. PID sensor for volatile organic compounds (VOCs) (Alphasense). temperature and relative humidity sensor (Atmospheric Sensors). high-sensitivity GPS module capable of accurate location and time measurement even inside buildings. microphone to characterise ambient noise, based on a hardware RMS level detector. data can be sampled at high rates, which are normally averaged over 20 seconds, with data transmission every 15 minutes. This can be configured to suit each application. communication link to remote database via GPRS. This includes the ability to 'store and forward' data in times when the network is down or temporarily overloaded. The unit requires a data-capable SIM card service, which can be provided either by Atmospheric Sensors or by other providers by discussion. local storage on 16GB SDCard of extended results from test for later recovery and to act as a backup of results sent over the GPRS link. mains power supply, with waterproof connector. externally visible LED to indicate unit status. the unit may be used either indoors, or outdoors if protected by a Stevenson Screen, or similar enclosure. Wall mount brackets are supplied with each unit, permitting easy installation.
