Droplets are wireless, battery-operated moisture sensors only a few inches wide. They are placed on the floor in high-risk areas, such as mechanical rooms, riser access panels, under HVAC/PTAC units, kitchen sink cabinets, next to toilets, and behind appliances like washer/dryers and dishwashers. When the probes on the sensor become wet, an alert is immediately sent to our monitoring platform, and it will continue to send repeated warnings every few minutes until the area becomes dry. The sensors will also periodically send "heartbeats" to our service so we can monitor the battery life and status of the sensors, as well as the health of the network itself.
Droplets are extremely low-power devices that should operate on one set of batteries for many years under typical use. In the event of a low-battery condition, we will notify customers with plenty of time to allow them to replace the batteries. Likewise, we will notify customers if a sensor unexpectedly ceases communications, such as if it is removed from the premises or malfunctions.
Private LoRaWAN Network
Perceptive Things uses a cutting-edge wireless networking technology called LoRaWAN. (LoRaWAN stands for "Long Range Wide Area Network".) This technology is designed to allow wireless communication over several miles in open air, or a few blocks in an urban environment, with very little power. Perceptive Things will install one or more LoRaWAN "gateways" to provide a private network for all Droplet sensors within the building. These gateways will be the only component requiring power. Gateways bridge the LoRaWAN network with the internet over a traditional LTE network, so they do not require access to any building-wide or tenant Wi-Fi networks. However, customers may wish to connect gateways to an existing network so it can maintain connectivity if the LTE network goes down.
Perceptive Things provides a web-based application for building staff and property managers to view sensor status and reports, and to administer users and attached sensors.
The application provides information on recent incidents, sensor location and status information, as well as related contact and communications preferences. Alerts can be delivered to one or more contacts...building staff, management company employees, and tenants. They can be delivered via email, SMS, and automated voice calls, which is useful for notifying a doorman station.
