My company built
Twine — a square green WiFi sensor block that was one of the first big tech Kickstarters back in 2011. We shipped Twine 12 years ago and are still supporting it.
Twine was the seed of a good idea that still doesn't exist. Arduino is like building your own car. Smart home devices are like leasing a compact sedan. A PLC is like a Mack truck. So we built Pickup, an environmental monitor/controller that works out of the box but has a modular architecture to fit your task.
It's a flexible little outdoor computer for growing, monitoring air quality, DIY science, etc. Plug in sensor cartridges or build your own; output analog signals, HTTP and MQTT to integrate with your software; and ready to drop anywhere. Yes, we like to tinker, but not to solve the same rote connectivity, power and deployment issues every time. This takes care of those, so you can focus on solving the interesting problems of your particular task.
Pickup has hit its goal on Kickstarter (our fourth!):
