This sensor and data manual may change due to technical improvement of the product without prior notice, please forgive me.

The company has the final interpretation of the sensor data manual.

Voltage data and air source data need to be provided before purchase.

Technical indicators:

Gas concentration detection range: 0 Other concentrations can be customized

Concentration resolution: 0.1%
Concentration detection accuracy: 1.5% F@ (5-55)
Sample gas requirements: water removal (no condensation); Dust filtration (? < 1 u m)
Detection cycle: 500ms

Preheating time: The machine can be measured, 10s to achieve basic accuracy

Digital Output: 9600bps?? UART???? 5V TTL / 3.3V CMOS
Inlet and outlet direction: no direction distinction

Operating temperature: below 10~50 (non-condensing)
Storage temperature: -20~65 below (non-condensing)
Relative humidity: 0 ~ 95%RH (non-condensing)
Maximum pressure: 150 kPa

Power supply: DC(5V-12V), 50mA
Dimensions: 45mm x 24mm x 24mm (L x W x H)

Sensor weight: 20g

Serial communication protocol
Baud rate: 9600bps

Character length: 1 start bit, 8 data bit, 1 stop bit, no check

Communication specification
All data in this agreement are hexadecimal data. "46" is decimal [70]

The protocol verification must contain 0x16 0x09 0x01 and CS bits. The data after the verification is correct and can be used normally.

By default, the sensor reports data twice every second. When the mainboard queries data, the sensor automatically switches to the answer mode and reports data to the mainboard instead of sending data twice a second.
