Watchman with Noise Sensor

This variation of Watchman product combines noise sensor along with temperature and humidity sensors. In addition to be alerted for changes in temperature and humidity, now you can also be alerted for: fire or burglar alarm, loud music, large gatherings or any other noisy events. It provides you additional set of data and alerting with increased coverage of events that can be monitored by your Watchman. 

Note that it is NOT a dB sensor and will not measure low and short-lived noises. It is designed to detect alarm / loud noise that lasts for a minute or longer. 

Noise is measured in relative values (10 to 100) where values between 10-50 represent quiet room and 80+ represents presence of loud noise. Here are the key characteristics:

• Watchman sends log every hour (can be changed to 15-min with subscription), however any time noise level goes above 85, log is sent immediately. 
• In addition, user can also configure (via the portal) Watchman's sensitivity level that represents increase-in-noise value to send an immediate log. By default, sensitivity level is 10 and can be changed from 3 to 30.
• For reliable detection of alarm (noise), recommend placing Watchman within 10 feet (of the alarm)
• Reported noise logs are based on a 3-sec noise capture and 10 such captures are averaged out to calculate a representative noise level. In other words, unit will report higher noise levels when they last for minutes.   The display, however, is updated every 3-sec and hence may show higher fluctuations. 
• Temperature and Humidity logs (and corresponding alerts) work the same way as regular Watchman.  
• Logs are reported to a cloud portal and hence can be accessed from anywhere
• Email/SMS alerts as temperature/humidity/noise exceeds user-configured thresholds
• Portal offers logs retention for record keeping / audit purpose
• Watchman connects with your existing WiFi (requires 2.4G WiFi)
• Watchman comes with our best-in-class support. Our customers are our representatives and we serve each support email with our full dedication. Product comes with 90 day warranty (extended to 1 year, for subscribed customer) and we offer life time support regardless of the warranty period.

Access to logs and 6-day history with email alerts (to your login email) are free-of-cost. However, if you are looking for additional features such as SMS alerts, power/internet loss detection, add users and emails with daily log snapshots etc, you will require a subscription.

Watchman logs every hour (can be changed to 15-min with subscription). It does read the environment every minute and sends the logs right away, if there is loud noise (i.e. 85+) or noise level goes up by 10+ (referred as "sensitivity" level).

pp-Code portal allows users adjust the sensitivity level for Watchman to immediately send log when noise level changes. By default it is set to 10, however user can change it from 3 to 30 from the portal. Lower the number, higher is the sensitivity (3 is the highest sensitivity whereas 30 represents the lowest). You will receive more logs with higher sensitivity (and vice versa).

It is important to configure alert settings such that alerts are triggered when really needed. Avoid both cases: too many alerts or too few alerts. As you run your Watchman for few days, you will have a better idea of your environment and its typical log values. You will be better informed to set/adjust your alert settings.

Please note that for an alert to be triggered, current log value must exceed the user configured alert setting. For example, Watchman sends a log with noise value at 60. If user has configured 65 for noise alert setting, portal will not trigger an alert.    

Noise sensor comes pre-calibrated, there is no need to adjust it. If you happen to alter the adjustment (blue square rotator), turn it anti-clock to it's limit (red light turns off). Then start rotating (very slowly) clock-wise. At some point, red light will turn ON. Stop rotating further the VERY moment red light turns ON. It will restore the factory setting of the adjuster.   

Avoid touching the black surface of (mic) sensor. If there is some dirt, blow it away gently (instead of rubbing the surface).
