I list my house on AirBnB, Vrbo, Booking and other STR platforms, will this help me?

  • Absolutely!  Many hosts need to monitor their property to maintain noise levels or smoking inside.  This unit will do that and alert your phone!

Who can use this device?

  • Anyone can purchase and use this monitor.  Landlords, property managers, parents, short term rental operators, schools, public buildings, etc.

How do I get the data from the detector?

  • You will download an app for your phone that will allow you to interact and get feedback from the detector.

Does it store info?

  • Yes, the app stores the data it receives and you can go back and retrieve it if you need to.  Everything is on a timeline so you can see if a sensor was triggered.

How many things will this detector monitor?

  • There are detectors built in for noise level, air quality, humidity, illuminescence, temperature and CO2

But I don't need that many sensors, I only need 1 or 2.

  • Great, you don't have to set alerts in the app for the ones you don't need, just use the ones you want.  Each sensor in the unit can be set up with custom alerts.

Can I adjust the thresholds?

  • Yes, on every sensor, via the app, you can adjust the thresholds for the alert trigger, so if you are getting false alarms, you can adjust the threshold to something that better suits you.

Will this device record what people are saying?

  • No, you are not spying on anyone.  It measures only the volume level of the sounds, it does not record (or listen to) what people are saying

Does the detector require a power source?

  • Yes, like many Particulate Matter (PM2.5) filters, it requires more power than is practical in a battery and must be plugged in to an outlet to operate

 

A PM2.5 sensor measures the concentration of fine particulate matter (particles less than 2.5 micrometers in diameter) in the air. These particles are small enough to be inhaled and can pose health risks. Here's how a PM2.5 sensor typically works:

🔧 Working Principle: Light Scattering

Most PM2.5 sensors use a laser scattering method (optical sensing). The process works like this:

  1. Air is pulled into the sensor via a small fan.

  2. A laser beam (or sometimes an LED) shines into the air sample inside a small chamber.

  3. Particles in the air scatter the laser light.

  4. A photodetector captures the scattered light at a specific angle.

  5. The intensity and pattern of scattered light are analyzed to estimate:

    • The number of particles.

    • Their size (e.g., PM1.0, PM2.5, PM10).

    • The mass concentration (usually expressed in µg/m³).

📊 Output

The sensor processes the data and gives real-time output:

  • PM1.0

  • PM2.5

  • PM10

Some advanced sensors also detect the number of particles per unit volume.

🔋 Components Typically Include:

  • Laser light source (often near-infrared)

  • Photodiode detector

  • Air flow system (fan or air pump)

  • Microcontroller (to calculate and transmit data)
