TH02: Temperature and Humidity Monitor

Overview

This sample periodically reads temperature and humidity from the Grove Temperature & Humidity Sensor (TH02) and display the results on the Grove LCD display.

Requirements

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

More details about the sensor and the display can be found here:

Wiring

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