Intro
We built a custom environmental sensor board for some project around the office like the fridge monitor and others. I thought I would share it with all of you and see what you would do with these types of sensors. The board includes both parabolic aluminized reflector luminare(PAR) and total solar radiation(TSR) photodiodes used for both visible and non-visible light and external Humidity and Temperature sensors.
Hardware
JCreate Connector:
-
We used an 2x8 pin .1" right angle IDC header from digikey for the connector. You could also use a 1x8 but we had the 2x8 headers in the office. Here is a link to where you can buy these headers.
Humidity and Temperature sensor:
The humidity and temperature sensor is an SHT11 from Sensirion. You can get them here. If you just want to build a quick prototype without doing surface mount soldering you can buy the SHT71 board from Newark that has a .1" pitch IDC header.
*PAR and TSR sensor:
The light sensors we used where the S1087 and S1087-1 photo diodes form Hamamatsu.
Here is a photo of the final board:

Here is a quick sample of the code used
