Flutter is a great platform for wireless sensor networks, and we're working on making it easy to find the sensors you need for your project.
We're looking at a handful of sensors we'll be including in our sensor kit (and perhaps individually?), but there's a lot of things in the world to measure. What kind of sensor do you want to use with Flutter?
A few we have already:
Humidity + Temperature (DHT11 and DHT22 types, for example)
Temperature (TMP36)
Motion (PIR)
Light
Tilit/Motion (Accelerometer/gyro such as MPU-6050)
Liquid PH
Let us know what other kinds of sensors you'd like here!
