Gas level reading
In addition to standard Watchman features (i.e. Temperature, Humidity and Party-Detection), it provides the gas-level monitoring.
The gas sensor monitors many kinds residential and industrial gases including: butane, propane, methane, carbon monoxide, alcohol, hydrogen, and smoke.
The sensor value (0-1024) reflects the approximated trend of gas concentration in a permissible error range. Higher the gas concentration, higher is the sensor value.
pp-Code allows configuring alerts on gas level values. Though the Watchman kit logs the stats every hour, the kit reads the gas level every minute. In case of sudden increase in gas concentration (+20), it sends the log to pp-Code portal immediately (does not wait for the next hour). Owners will receive instant alert (if it exceeds the configured threshold).
[Please note that it does not represent the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which cannot be done with a single gas sensor. If you intend at obtaining the gas concentration at a very precise level, then we don’t recommend this gas sensor. ]
It works along with Temperature, Humidity and Party-Detection readings as well as corresponding email / SMS alerts.
You can also define alerts for higher Gas levels.
Watchman monitors the gas concentration in air. The value of the concentration is relative to the environment of Watchman kit. As gas concentration goes up, Watchman will show higher values for gas level.
In order to establish normal gas levels of your environment, please place the Watchman kit in fresh air. Let it run for 24-48 hours. Make a note of gas levels that it reports. This will help you determine what is normal gas level reading at your location. Once known, you can then define higher thresholds for your alerts. For example, if your Watchman reads gas level around 300ish - when placed in fresh air - you may want to set the alert threshold at 350.
