| 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: |
| |
| - `Grove Temperature And Humidity`_ |
| - `Grove LCD Module`_ |
| |
| 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 SDA (I2C). |
| The LCD display requires 5 volts, so the voltage switch on the shield needs to |
| be on 5v. |
