GeneralA smaller size CO₂ sensor module, suitable for limited space applications like Indoor Air Quality, HVAC, Stove, Air-conditioner, Vehicle drowsiness warning, Gas measurement and so on. S-200 is much favored by Customers with long life cycle and high accuracy.One month period Automatic Re-Calibration mode and 10 minutes Manual Re-Calibration mode are supported as default.Features• Non-Dispersive Infrared (NDIR) technologyused to measure CO₂ levels.• Output mode : AVO, TTL UART, I2C• Operation Modei.Factory Calibration Status Modeii.Periodic Automatic Re-Calibration mode(ACDL :Automatic Re-Calibration inDimming mode)※Sensor has 2 mode as default so that theuser’s design could adopt those mode atchoice.• Re-Calibration Function Supporti.Low signal to pin 11 of S-200 for MCDL,signal again to pin 13 to return to ACDL.ing Re-Calibration Jig (TRB-100)• Size : 33mmx33mmx13mmTCC ELTCarbon Dioxide (CO₂) ModuleModel : S-200Version 2.0深圳市深国安电子科技有限公司地址:广东省深圳市龙华新区牛栏前大厦C507 网址:www.singoan.com www.singoan.com.cn www.shenguoan.com蒋小姐:134 2876 2631 电话:86 755-85258900S-200SpecificationsGeneral PerformanceOperating Temperature range0 ~ 50℃Operating Humidity range0 ~ 95% RH (Non-condensing)Storage Temperature-30℃ ~70℃CO₂ MeasurementSensing MethodNDIR (Non-dispersive Infrared) Measurement Range0 to 2,000/3,000/5,000/10,000/30,000ppm (Optional)Accuracy±30ppm ±5%Response Time (90%)60 secondsSampling Interval4 secondsElectrical DataInput Power5.0V (±1% Regulation)Power ConsumptionNormal : 20mAMax : 380mA at lamp on peakOutput connector4 pin, 10 pin (2mm pitch Socket) Output SignalUART38,400BPS, 8bit, No parity,1 stop bit TTL LevelI2CSlave mode onlyInternal pull up resisterUnder 50kHz ClockTTL LevelAnalogVDC 0.5 ~ 4.5VPin DescriptionPin No. Description1/3 +5V VCC2/4/9 GND5 TTL RXD (MCU→S-100)6 TTL TXD (MCU←S-100)7 I2C SCL8 I2C SDA10 Analog Output (0.5~4.5V)11 10 min.

Using pin-signal of S200, Apply TTL Low signal to pin 11 for 11 minutes, orMethod 2. Using Jig Board (TRB-100: T est and Re-Calibration Board, On sale as option).※T o activate ACDL or MCDL function, the user’s application must be designed to give Low Signal on 11st and 13rd pin of S-200 Board.深圳市深国安电子科技有限公司地址:广东省深圳市龙华新区牛栏前大厦C507 蒋小姐:134 2876 2631 电话:86 755-85258900网址:www.singoan.com www.singoan.com.cn www.shenguoan.com。
