7Overview
8********
9This sample periodically reads temperature and humidity from the Grove
10Temperature & Humidity Sensor (TH02) and display the results on the Grove LCD
11display.

17This sample uses the TH02 sensor and the grove LCD display. Both devices are
18controlled using the I2C interface.

25Wiring
26******
27
28The easiest way to get this wired is to use the Grove shield and connect both
29devices to I2C. No additional wiring is required. Depending on the board you are
30using you might need to connect two 10K ohm resistors to SDL and SDA (I2C).
31The LCD display requires 5 volts, so the voltage switch on the shield needs to
32be on 5v.
