CurieJet® Air Monitor Module

- World’s Smallest & Pump-driven Air Monitor Modules

MicroJet Technology has designed a series of Pump-driven Environmental monitor Modules with its world-leading patented technology. By leveraging our CurieJet® customized Air Pump "core module", MicroJet Technology has developed a series of Air monitor Modules with extremely small size and can even be integrated into Smart Watch or Mobile Phone for air quality monitoring. Air Pump is very important to circulate air actively in time and drive air sensor to respond quickly. We inhale more than 10,000 liters of air per day. The very air we breathe is growing dangerously polluted, nine out of ten people now breathe polluted air, which kills 7 million people every year. That explains why personal air monitoring in time are important.

Air pollutions are mainly in gas and particle forms. Gas air pollution may be measured in IAQ, CO2 equivalents, etc. IAQ (Index for Air Quality) is related with VOCs volatile harmful gas, HCHO or other cancer-causing material. CO2 equivalents are derived from VOCs and CO2 in human’s exhaled breath and are very close to indoor CO2 level in living spaces, including homes and offices. (Please refer BME680 Environmental Sensor page 9 & 25 of )

Particle air pollution may be measured in PM2.5, PM10 and even PM1.0 level particulate matters and dust.

G200 Gas Sensor Module integrates an IAQ and CO2 equivalents measuring BME680 Environmental Sensor with our customized air pump, air chamber and MCU. G200 has very tiny size of 23.6 x 15.2 x 3.5 mm. It is also water-proof and dust-proof designed. Upon request, we can custom different Gas Sensors for new models of gas sensor modules. Please visit G200 demonstration here:

P700 Particle Sensor Module uses laser light with Mie scattering theory to measure PM2.5, PM10 and even PM1.0 particulate matter and dust in the air. It adopts our customized air pump, air chamber and MCU and is the world’s smallest optical laser PM 2.5 sensor with size only 29 x 29 x 4.9 mm. It is the smallest size in the world with only 1/4 volume of other optical laser PM2.5 sensors. Please visit P700 demonstration here:

P750 Particle & Gas Sensor Module takes the same size of P700 and use laser light with Mie scattering theory to measure PM2.5, PM10 and even PM1.0. P750 also integrates an IAQ and CO2 equivalents measuring BME680 Environmental Sensor by customized air pump, air chamber and MCU. Upon request, Pressure altitude measurement can also be supported.

ADDWII APP is available under licensing to support various functions. ADDWII APP support Air Quality Status, Histogram, Camera Shot, Air Map, Personal Trail, Knowledge Info, Account, etc. and create BIG DATA via AI in CLOUD to make the end products become IOT and AIOT devices.

Upon request, EVM10A Evaluation Board & Bluetooth Interface Module can be supported for end product developers.
