Data Sheet The MiCS-VZ-87 is an integrated sensor board for Indoor Air Quality monitoring. The MiCS-VZ-87 combines state-of-the-art MOS sensor technology with intelligent detection algorithms to monitor VOCs and C02 equivalent variations in confined spaces, e.g. meeting rooms or vehicle cabins. The signal output can be used to control ventilation on- demand, saving energy and reducing cost-of-ownership. Detectable gases • Volatile Organic Compounds VOCs • equivalent Carbon Dioxide C02(equiv) Conversion from analog output signal Vout of MICS-VZ-87 to equivalent Carbon Dioxide concentration in ppm Comparison between MICS-VZ-87 output signal and NDIR C02 sensor signal over a duration of 4 consecutive days Supporting your great ideas a member of the Angst + Pfister Group

Data Sheet I2C is a simple two-wire chip-to-chip digital communication protocol. The protocol is master oriented but allows bidirectional communication on just two communication lines. MASTER to SLAVE SLAVE to MASTER Address byte = OblllOOOOO (Write) Address byte = OblllOOOOO Command = ObOOOOOlOO Data byte 1 = ObOOOOllOl (example of data) Data byte 1 = Obxxxxxxxx (not used) Data byte 2 = ObOOOOOOOO (constant) Data byte 2 = Obxxxxxxxx (not used) Address byte = OblllOOOOl (Read) Data byte 1 = 13 => 13/255 = 5% I2C bus allows communication between several masters and several slaves used in...
