	The wire at the top right is from the waterproof temperature sensor - and it usually comes with three wires, red black and yellow. The wire which looks orange on the picture should be connected ~~(signal)~~ and you probably won't have a white wire. For bonus points if you have time, you can connect additional sensors such as humidity, light level and even pH. The code on the device detects which sensors are connected automatically during startup. Just to give you a chance, the light level and pH sensors use I2C and so connect them to pins #4(SDA) and #5(SCL) as well as power. The humidity sensor gets connected to power and the signal goes to pin #12. You also need a 4.7k resistor between positive and signal - like this:		The wire at the top right is from the waterproof temperature sensor - and it usually comes with three wires, red black and yellow.
