 Sensor life
15 years in normal commercial environments with ABC on (Note 3)
 
Compliance with
CE conformity declaration not required because it’s not a product directed to end user. Our customers have to make this declaration for their entire product.
RoHS directive 2002/95/EG
SenseAir is going to perform immunity and emission tests anyway to confirm compliance of the module in immunity and emission
Other tests / approvals are available on request, contact SenseAir

Note 1: Sensor is designed to measure in the range 0 to 5000 ppm with specified in the table accuracy. Nevertheless exposure to concentrations below 400 ppm may result in incorrect operation of ABC algorithm and shall be avoided for model with ABC on.
Note 2: Sensor provides readings via UART in the extended range but the accuracy is degraded compared to specified in the table one.
Note 3: In normal IAQ applications. Accuracy is defined after minimum 3 weeks of continuous operation. However, some industrial applications do require maintenance. Please, contact SenseAir for further information!
Note 4: Accuracy is specified over operating temperature range. Specification is referenced to certified calibration mixtures. Uncertainty of calibration gas mixtures (+-2% currently) is to be added to the specified accuracy for absolute measurements.

SenseAir® S8
Possible functionality of other members in SenseAir® S8 family
 Serial communication
UART, Modbus protocol (Note 5)
Direction control pin for direct connection to RS485 receiver integrated circuit.
FastStream protocol
delivering dedicated measurement data with dedicated time intervals is under development
Alarm output, Open Collector
 
Normally Conducting after power up,
Non conducting (high level) at > 1000 ppm,
return to conducting (low level) at < 800 ppm
Non Conducting (high level) at error detected
 
Contact SenseAir for other optional functionality of OC and threshold configuration.
PWM output, 1 kHz
 
0 to 100% duty cycle for 0 to 2000 ppm
 
3.3V push-pull CMOS output, unprotected
Contact SenseAir for other optional output ranges.
Forced calibration
Background calibration in fresh air (400 ppm) by forcing bCal input Low for about 4 sec.
 
Keeping bCal input low for more than 16 sec forces sensor to perform zero (nitrogen) calibration
