Welcolme to my Shed Pi Data Logger. At the heart of the data logger is a raspberry Pi Model B. This is set up in the shed and receives a digital signal from the time clock. The internal tempearture of the Shed is also transmitted by the pi
The Model B raspberry Pi is at the heart of the data logger. There are two inputs into the pi, a digital signal On or Off and an I2C signal, DataByte. The Digital signal is sent from the Sangamo Time clock controller which controls the Shed outside light.
