It’s a Dirty Job, but Some Sensors Can Do It

I recently toured Freescale’s IoT truck demo at its Tempe facility. There were more than 120 new working demos on display. Here is one of many that I will highlight in the next few days.

Outdated methods of monitoring drainfield levels (by putting a dip-stick down the inspection ports) take a great deal of time to complete. Manual measurements can be “hit and miss,” and may not allow detection of dangerously high liquid levels in time to avert a system failure.

Septic SitterTM keeps watch over septic tank and drainfield liquid levels, 24 hours per day, 365 days per year.

The system can send maintenance notifications and alerts to any Internet-connected device, allowing corrective action to be taken, before hazardous and costly backups or failure occurs. The system uses a non-contact sonar sensor technology.

Historical and real-time liquid level data is stored in the cloud. Access can be provided to designated service personnel, who can trouble-shoot septic system problems remotely.

Graphs and reports can be provided to regulators or prospective home buyers, to demonstrate proper septic system operation.

The brains of this system is the Kinetis K6x Ethernet Crypto MCU offering IEEE® 1588 Ethernet and full and high-speed USB 2.0 On-The-Go, including options with USB crystal-less functionality.

Watch Planet Analog for more of these neat Freescale design ideas to come.

    This is one of those areas where we expect the ability to network systems will provide a new dawn in how we understand our world and systems. Imagine if the WIFI can be strong to also work in these systems so that the sensor that is watching underground can relay data via apps without having a more sophisticated alternative that will cost more money. It is possible that no aspect of our homes and lives will be ungoverned! Sensors with TCP/IP protocol will do great things in this era.

    App might be reliable in order to receive notification any place. More smart sensors could be developed and communicated to App through internet & Cloud. For communication, different protocols are being developed among sensor, App, and internet as LTE is getting popular.

    You do not even need LTE for this type of system. You just need a wireless communication network that is available including 2G, 3G or anything there.

    I believe your wireless connection should be feasible enough to cater such kind of application, speed is the key here, further wifi-offload seems good option here.

    When the speed of the wireless or WIFI is 100X faster than the processing capacity of the sensor, nothing much has been achieved. When you have inertial sensors that clock in 100Hz in a GHz wireless and people still saying the system is not fast, it means they do not even understand the device they are playing with. I see it all the time.
