BW Technologies XT-XWHM-Y-NA GasAlertMax XT II 4-Gas Detector with Pump, Combustible, O2, H2S and CO, Yellow

Four-gas detector for surveying levels of H2S, oxygen (O2), carbon monoxide (CO), and combustibles in natural and industrial environments, and in other personal safety, training, research, and ambient air monitoring applications.
Electrochemical cell sensor measures H2S and carbon monoxide levels in ppm, capillary-pore fuel cell measures oxygen in percent by volume, and catalytic bead combustible sensor measures explosive gases in percent LEL.
Audio, visual, and vibration alarms alert simultaneously when ambient H2S, oxygen, carbon monoxide, and combustible gases reach preset low, high, TWA, or STEL levels.
LCD screen shows up to four ambient gas concentrations, battery level, alarm condition, and the status of calibration, bump, and sensor self-tests.
Integrated diaphragm pump allows for localized sampling of the atmosphere for more precise readings than those generated through diffusion.

The BH1750FVI sensor to measure the ambient light level. BH1750FVI is a calibrated digital light sensor IC that measures the intensity of incident light and converts it to a 16-bit digital number..
It can measure the ambient light intensity ranging from 0 to 65535 lux (L). Lux is an SI unit for illuminance and is equal to one lumen per square meter. The BH1750FVI sensor directly gives the output in Lux..
The sensor's spectral response function is approximately similar to that of the human eye. The sensor output can be accessed via an I2C interface. The 7-bit I2C address is 0 × 23 if the ADDR pin is grounded, or if the 0x5C ADDR is bound to VCC..
