|ghpi circuit board rendering|
The board connects 1-wire temperature sensors to a Raspberry Pi for logging and display. There are also connections for an I2C/TWI display and an SPI RF24 wireless module. My plans is to release the source on github and sell kits. Please leave me a comment if you are interested in either one.
GHPi is what I am calling the project, which is currently in the prototype phase with my friends at c-jgreenhouse.com. Go buy some flowers from them.
