Outdoor Sensor Array


How many sensors can we plug into one Arduino and setup outdoors? This is how many I was able to cram into one Project Box.

The system uses a ESP8266 Wifi / Arduino Card with a screw terminal Shield. — I attempted to run it all with two 12 volt solar panels with a solar charger. Didn’t have enough juice, so ended up just plugging into outlet located outside.
