ORIGIN IOT

Hi David,

I've not heard of them, but there are plenty of other IoT offerings that are currently more well-known and mature. What's the use-case? Also, is it to be an Industrial or business or consumer product? What connectivity is needed, mobile, or WLAN?

Hey Shabaz,

Thanks for the reply. They're big in GPS and quite good quality; I was looking for a GPS chip and I came across their IoT offering which has majority of sensors I need included (9 axis IMU, Pressure, Temp, charge control/fuel gauge, etc). While they do have GSM included in their set I don't require it. It does have one of their high end GPS chips so can ignore that for now.

Use case will be a consumer product diving computer of sorts (GPS for entry exit points only). I will attempt to use the IMU for underwater tracking as an idea down the line, for now compass will be the main active sensor. I am missing Bluetooth from this setup so will require it to sync with a smart device/computer.

Cheers

Hi David,

If you don't need mobile (cellular) connectivity then another option to use a different device. I don't see anything compelling about using a board from an unfamiliar supplier, for which you might not find much example demo code (I'm speculating, could be totally wrong).

If you're looking for something ready-made I don't think you'll find an all-in-one, otherwise you can assemble it from several boards or chips.

For a board-level option, you could examine TI Sensortag, which has about 10 sensors on it and Bluetooth LE. It is missing GPS, but that's easy to attach using (say) a serial interface. There are some GPS modules here: https://www.newark.com/w/c/wireless-modules-adaptors/prl/results?st=gps

If you want a chip-level solution to build your own custom boards, you can explore the documentation of the TI Sensortag (the documentation contains schematics and bill-of-materials and so on). If you need a fuel gauge then Maxim semiconductor website has some ICs that could help (will need to be assembled into a circuit, they may have ready-made eval boards, but it sounds like you need it to meet some size constraints at a minimum, if not other constraints too if it is to be used underwater, so a custom board is likely needed anyway). Some things may not work well underwater incidentally, e.g. radio-related.

Hey Shabaz,

I had already selected the following chips for my project:

IMU (Accel, Gyro, Magneto, Temp)     -     LSM9DS1TRLSM9DS1TR

Pressure Sensor  -   MS580314BA01-00

RTC (Clock, Temp)     -     MAX31341BEWC+

Fuel Gauge     -     STC3117

I was looking into BT and GPS chips to complete the system when I came across SoC for both of these as I still would need a processor to run it, I then was researching to go SoC BT or SoC GPS - which then evolved to IoT systems. While the origin IoT does come with pressure sensor, it doesn't cover the depths that I need (the one selected above goes to 14 bar / ~140m) and I would have to of added the MS5803 anyways.

I was originally going to have an engineer design the PCB with each of the individual chips, this in the long run would be cheaper for manufacturing - but increase the dev cost and time. As I'm far from an Elect Engineer I figured this may help get me moving again.

I'm currently stuck at a few places - hence I jumped on here again - one is the differences in developing the firmware for Chip SoC's vs IoT SoC systems as these say they have systems in place to develop with their systems.

I had a quick look at the TI Sensortag. That could be worth contacting TI again (already been chatting with them for some of the chips) and see what they recommend.

All of the Radio/GPS will be for above water only, I will be looking for future iterations for short range wireless which would be a lower bandwidth (wireless tank receivers etc).

Basically I think I need to go back to Uni and start all over again haha.
