I2OT Water Tank Hardware Customization Options
IoTini developed a system for monitoring urban rooftop water tanks. The first version of the system, in the field today, measures water temperature and outside temperature every hour and then reports through the cloud every four hours. The system is optimized for extremely low power sleep mode so the unit can run unattended for five years from a single internal primary battery.
The hardware was created with broader applications anticipated. A second product version targeting farm, ranch and industrial applications adds tank level (submersible pressure sensor) and flow measurement capability.
The plug and play system includes the remote hardware, a web Dashboard for managing sensors, and Android/Apple mobile apps. All hardware and software is developed in-house.

The urban tank monitor system uses LTE CAT-M cellular connectivity.
This protocol is optimized for low power, greater range, and improved indoor penetration compared to previous generation cell options.
The farm and ranch hardware can also be configured to use LoRa for wireless communications. LoRa, an acronym for Long Range, is another newer wireless protocol that has gained significant traction as an industry standard for sensor applications. LoRa can be implemented as a private network, or where available, can be run on a public network (e.g. Senet).
LoRa is well matched to sensor and control applications with low data rates and where transmissions are no more frequent than a couple minutes apart.
IoTini can supply a complete private network LoRa solution including Gateway and LoRaWAN Network Server.
