Raspberry-Pi driven temperature and humidity sensing via DHT22.
Short-URL: http://git.io/vRFkn
v1.1 Boards are orderable from OSHPark at the following links:
- PiTempLoggerv1.1-PiSide @ $34.50 per 3 boards
- PiTempLoggerv1.1-Sensor @ $12.00 per 3 boards
They have been prototyped on a local board-fab machine, and a first run is en-route to the JQI.
For one sensor baord:
- 1 DHT22 from Adafruit?
- 1 of the above PiTempLoggerv1.1-Sensor
- 1 of 1-10k 1206 SMT resistor (use a lower resistance, e.g. 1-2k, if your ethernet cable is over 15 feet)
- 1 of 100nf 1206 SMT capacitor
- 1 of ethernet jack (Man. Part No. 555164-1, TE/Amp, get from any distributor)
- 1 Ethernet cable to connect to RPi (whatever length you need)
Per pi:
- 1 of the above PiTempLoggerv1.1-PiSide
- 8 of ethernet jack (Man. Part No. 555164-1, TE/Amp, get from any distributor)
- 1 of 26-pin 2x13 header
- 1 ribbon cable, either:
- 26 pin
- 40 pin
- "Downgrade" cable from Adafruit <-Could also be made yourself with ribbon or connector
- 1 ethernet cable for network access
