# JC42 Driver Test
## Introduction
This test will test if the jc42 compatible temperature sensor is working.
## Configuration
There are three parameters to configure:
* `TEST_I2C` — I2C device to use.
* `TEST_I2C_ADDR` — The sensor address (usually 0x18).
* `TEST_I2C_SPEED` — The sensor address (usually I2C_SPEED_NORMAL).
## Expected result
The sensor should continuously (every 1 sec) output the temperature. The precision should be two digits.
