Introduction:We wanted an easy universal solution to small scale automotive and aerospace data collection. The plan was to use a trifecta of argons with two arbitrarily placed DHT22 sensors to output data on a single display.
The ThingSpeak live data can be seen by following the link below.
Project Overview:Our goal for this project was to have two Particle Argons communicate to one central data collection argon. The two external Argons were both wired up and coded with the DHT22 sensor as well as the DHT22 code. These two devices were programmed to publish data to the cloud with the use of the Particle.Publish function. The third argon was wired up with a 16x2 LCD display in order to watch live data updates. The code for this argon was essentially grabbing data from the cloud with the use of the Particle.Subscribe function. In this example only a temperature/humidity sensor was used, but this can be replaced with any sensor with little change to the code. The network allows for the flexibility of multiple sensors feeding into one display. Since the devices are publishing to the cloud, they can be mounted anywhere where there is a power supply and a wifi signal.
