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
