Carbon Dioxide(CO2) Module

General The S-100H CO2 module is designed to be perfectly compatible with H-550.This model is also the world smallest sensor and can be integrated into wide range of application product from small wall-pads to building ventilation controller. Its main application area is Indoor Air Quality, HVAC, Stove, Air-conditioner, Vehicle drowsiness, Gas Equipment. Features Non-Dispersive Infrared(NDIR) technology used to measure CO2 levels. The world smallest size Pre-calibrated Provides output signal proportional to CO2 level. Three available output : AVO, TTL UART, I2C 2.54mm pitch header connector Model available to interact with other devices. Gold-plated sensor provides long-term calibration stability. Installed re-calibration function(Automatic or manual) Specification General Performance Operating Temperature 0 ~ 50°C Operating Humidity 0 ~ 95%RH(Non-condensing) Operating Environment Residential, Commercial spacesRoom Controller Storage Temperature -30°C ~ 70°C CO2 Measurement Sensing Method NDIR(Non-dispersive Infrared) Measurement Range 0 to 50,000ppm(expandable up to 10,000ppm) Accuracy ±30ppm ±5% of measured value Step Response Time(90%) 60 seconds Sampling Interval 3 seconds Electrical Data Power Input 9 ~ 18VDC(±10% Regulation) Current consumption Normal : 15mA / Peak : 160mA Output connector 11 pin Output Signal UART 38,400BPS, 8bit, No parity, 1 stop bitTTL Level Voltage 3.3~4.5V I2C Slave mode onlyInternal pull up resisterUnder 400Khz ClockTTL Level Voltage 3.3~4.5V Analog Voltage Output VDC 0.5 ~ 4.5V(linear output)
