It's easy to imagine multiple simple designs. You can couple it with an ESP2866, for example, using a number of attinys to access their analog inputs, or with a CAN-SPI head collecting data from multiple sensors, processing and then reporting through an ESP2866.
- Tepix 11y agoThe ESP8266 is quite slow, network wise. You could hook up the sensors to the Pi Zero directly using the GPIO ports and use a cheap USB WiFi adapter to upload the data.
- jon-wood 11y agoIn the context of the device the parent comment describes the ESP8266 being quite slow doesn't really matter that much, it just needs to be fast enough to push whatever telemetry its collecting on a regular basis, which an ancient modem could probably manage. Not everything requires the ability to push data at 10s of Mbps.
- sklogic 11y agoI guess it would be harder to power an USB WiFi adapter. And it's not going to be cheaper than ESP2866.
- jgowans42 11y agoThe ESP2866 is perhaps something to consider. Something like it really should have come built in though. (IMHO)
