The Smart Drain Cap is a conventional drain cap,fitted with electronics to sense water backing up in the drain, and send status information to the building manager’s mobile phone via cloud. This innovative device helps building management stay ahead of water spillage catastrophes and take timely preventive/corrections actions in case of a potential blockage.
The device consists of two rope sensors that detect water backing up from the main line. The signal from rope sensors is processed & forwarded by the main controller circuit to the cloud, and on to users’ devices.
Blockage Detection
The Smart Drain cap is equipped with sensors that detect blockages in the sewage system before the water spills over.
Timely Notifications
The drain cap sends blockage notifications to the maintenance teams via a mobile app and a web app hosted on AWS.
Dual Communication Protocols Supported
AMS-IoT developed two versions of the drain cap – one using Wi-Fi technology for residential properties and another using LoRaWAN technology for commercial buildings.
Multiple Notification Channels
Notifications can be received through both the mobile app and the web app, providing flexibility and convenience for users.
Microcontroller
The drain cap utilizes the ESP 8266 microcontroller.
Communication Protocols
The drain cap supports both Wi-Fi and LoRaWAN.
Electrical Ratings
Power Supply:
2.8V, 6uA
Schematic Capture & PCB Layout:
The schematic capture and PCB layout were done using Altium.
Programming Language
The firmware for the drain cap was developed using C.
Wi-Fi(802.11i)
The drain cap designed for residential properties utilizes Wi-Fi for communication. This communication protocol is most suitable for residential properties because of its ubiquity in homes all over the country.
LoRaWAN
The drain cap designed for commercial properties uses LoRaWAN communication. LoRaWAN has specific properties that are suitable for operation in large commercial buildings with high density of sensors and large area to cover.
Cloud Integration
The drain cap is integrated with Aquazen through TTN, allowing seamless connectivity and data storage.
Residential Properties
The drain cap version using Wi-Fi technology is compatible with residential properties, providing effective blockage detection and notifications for homeowners.
Commercial Properties
The drain cap version using LoRaWAN technology is compatible with commercial properties, allowing efficient blockage detection and notifications for building owners and facility managers.
North American Frequency Band
The LoRaWAN version of the drain cap is compatible with any LoRaWAN gateway operating on the North American frequency band.
