Personal Gas Detector Monitoring CO, NO, NO2, O3 Gas With GPS Receiver

Personal Gas Detector Monitoring CO, NO, NO2, O3 Gas With GPS Receiver   Descriptions: 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. Personal Gas Detector Monitoring CO, NO, NO2, O3 Gas With GPS Receiver specifications:
1.accurate electrochemical cells (Alphasense A4) monitoring CO, NO, NO2, and O3. Other sensors available on request.
2.optical particle counter (Alphasense).
3.temperature and relative humidity sensor (Atmospheric Sensors).
4.MEMS 3-axis accelerometer to detect movement.
5.GPS module with integrated antenna
6.microphone to detect ambient noise level.
7.high-capability 32-bit ARM microcontroller.
8.bi-colour LED to indicate battery state-of-charge and correct operation of the unit.
9.battery and compatible charger circuit to give 24 hours running and some contingency (two 18650 lithium-Ion cells).
10.SD Card storage up to 32GB.
11.supplied with a shoulder strap and belt clip so can be worn in different ways.   Personal Gas Detector Monitoring CO, NO, NO2, O3 Gas With GPS Receiver details: Basestation: 151 W x 178 D x 90 H.
