Figure 4. Complete set of WSSFCEX-GHC flammable gas sensor
The GHC flammable gas sensor measures the flammable gas concentration of the surrounding air.
The Sigfox-Ready wireless transmitter is to read the measurement values from the GHC sensor and performs the
scaling and calculation to deliver accurate outputs.
To understand how the GHC flammable gas sensor works, please refer to
for a complete understanding of
this measuring technique.
Below are some important configuration parameters which affect the operation of the device like battery life,
measurement accuracy, and alert threshold.
For Battery life estimation, please refer to this link.
measure_period | Default = 300s
This is the time period for the wireless transmitter to wake up and take the measurement from the transducer.
The default value is 3600s. Users can reduce this value, but smaller value, shorter battery life!
cyclic_data_period | Default = 1800s
Interval time to send an uplink message regardless of any conditions
sensor_response_time | Default = 100s
This value will affect the measurement accuracy.
DO NOT change this value!
Those configuration parameters can be changed by downlink or offline tools. For other configuration parameters,
please refer to the next section.
