MONITOR, AQM_ID, SENSOR_PARAM_DOWNLOAD, SENSOR_TYPE
29*. Download param reply command. The command will get the sensor's all parameters. The total reply
stream length is 50 bytes.
SENSOR, HTR, OFFSET, TEMPRESET, TIMERESET, TEMPREAD, TIMEREAD, H0, H1, H2, PWML,
PWMH, CYCLENUM, CHECKSUM
* SENSOR_PARAM_DOWNLOAD - 1 byte command, its value = 0x08
* SENSOR_TYPE - 1 byte sensor code.
* HTR, OFFSET, TEMPRESET, TIMERESET, TEMPREAD, TIMEREAD, H0, H1, H2, PWML, PWMH,
CYCLENUM
- are 4 bytes floating point value,
30*. AQM sensor module parameters upload command. The command consist of two data streams
one upload invoking command 4 bytes, then followed by a parameters stream which is 50 bytes.
Command:
MONITOR, AQM_ID, SENSOR_PARAM_UPLOAD, SENSOR_TYPE
Parameters:
MONITOR, HTR, OFFSET, TEMPRESET, TIMERESET, TEMPREAD, TIMEREAD, H0,
H1, H2, PWML, PWMH, CYCLENUM, CHECKSUM
* SENSOR_PARAM_UPLOAD - 1 byte command, its value = 0x09
30a*. Acknowledge reply command 5 bytes:
SENSOR, SENSOR_PARAM_UPLOAD, SENSOR_TYPE, CHECKSUM
* The reply is used for confirming the sensor parameter upload was successful
31*. Sensor resistance request command, its format is a 4 bytes stream:
MONITOR, AQM_ID, SENSOR_RESISTANCE, CHECKSUM
* MONITOR - information request command header, its value is 0x55.
//* SENSOR_TYPE - gas concentration request command, please refer section 2 for details.
* SENSOR_RESISTANCE - 1 byte command (0x0D) to request sensor resistance value.
* CHECKSUM - the data stream's check sum - that makes the command stream total
bytes sum to be zero.
Example (To poll ozone sensor resistance): 0x55 0x01 0x0D 0x9D
32*. Sensor resistance request command reply data stream, 15 bytes:
SENSOR, AQM_ID, SENSOR_RESISTANCE, SENSOR_TYPE, BASE_R, SENSOR_R,
SENSOR_STATUS, RESERVED, CHECKSUM
* SENSOR - 1 byte monitor reply data stream header, its value is 0xAA.
* SENSOR_TYPE - 1 byte gas type, its value will be same as the request command value, see section 2
for details.
* SENSOR_RESISTANCE - 1 byte command (0x0D)
* BASE_R, SENSOR_R - 4 bytes floating point data value, base line resistance and sensor resistance.
* RESERVED - 1 byte reserved space.
* SENSOR_STATUS - 1 byte sensor status indication, refer section 3 for details.
* CHECKSUM - 1 byte the data stream's check sum - that makes the command stream total bytes sum
be zero.
33*. Sensor heater temperature request command, its format is a 4 bytes stream:
MONITOR, AQM_ID, SENSOR_TEMP, CHECKSUM
* MONITOR - information request command header, its value is 0x55.
//* SENSOR_TYPE - gas concentration request command, please refer section 2 for details.
* SENSOR_TEMP - 1 byte command (0x0E) to request sensor resistance value.
* CHECKSUM - the data stream's check sum - that makes the command stream total
bytes sum to be zero.
