Personal air quality monitor monitoring CO, NO, NO2 , and O3 AS520

Personal air quality monitor monitoring CO, NO, NO2 , and O3 AS520 Description: A wearable air quality monitoring system that makes use of a complementary range of sensing technologies to provide a complete and reliable assessment of the air quality in the immediate vicinity of the wearer. Electrochemical cells, a laser optical particle monitor, temperature and humidity sensors are included in the system, which also incorporates a highly-sensitive GPS receiver and 3 axis accelerometer. A microphone is fitted to monitor ambient noise. A basestation provides a docking unit to store the sensor unit at night and to allow access to a regulated 12V supply to power the battery charging circuit. The basestation is fitted with a GPRS modem, patch antenna and SIM card, which are used to transmit the data that are saved on the unit during the day to a central monitoring site.   Features: • accurate electrochemical cells
(Alphasense A4) monitoring CO, NO, NO2,
and O3. Other sensors available on request.
• optical particle counter (Alphasense).
• temperature and relative humidity sensor
(Atmospheric Sensors).
• MEMS 3-axis accelerometer to detect
movement.
• GPS module with integrated antenna
• microphone to detect ambient noise level. • high-capability 32-bit ARM
microcontroller.
• bi-colour LED to indicate battery state-ofcharge
and correct operation of the unit.
• battery and compatible charger circuit to
give 24 hours running and some
contingency (two 18650 lithium-Ion cells).
• SD Card storage up to 32GB.
• supplied with a shoulder strap and belt
clip so can be worn in different ways.   Specifications: Basestation: 151 W x 178 D x 90 H. Weight 352g.
Sensor unit: 100 W x 83 D x 130 H. Weight 534g.
Power supply: 1.2A max off 12V power supply (during charging) Weight 180g.
System includes: basestation, sensor unit, power supply, shoulder strap. A belt clip is fitted to the rear of the unit.                     Welcome to your inquiry !
