Title: Moteino and Weathershield is there space for LDR ?
Post by: gert on September 12, 2015, 04:52:31 PM
Hello All,

Just signed up for the forum and want to get started with Moteino for my next weatherstation project.
Question : There is a tiny extra space on the weatherstaion shield. Would that be enough to add an LDR for daylight measurements? (Needs access to VCC/GND and an analog input of the Arduino)

Thanks,
Gert

Welcome!

The WeatherShield has 8 independent rows of 3 holes that can be used for additional circuit and should be enough for what you need.  You can also tie into the I2C bus used by the TH & Baro sensors so you can add a digital ambient light sensor.  You should be able to find some breakout board with a 4 pin inline header, which will fit nicely in the prototyping area.  For example, the Lumiosity sensor from Sparkfun (https://www.sparkfun.com/products/12055) will give you a much greater dynamic range than an analog sensor will.

For power you'll have Vin and 3.3V on the board.
