+
+#### Examples
+
+Basic measurement
+
+```
+import mlx90614
+from machine import I2C, Pin
+i2c = I2C(scl=Pin(5), sda=Pin(4))
+sensor = mlx90614.MLX90614(i2c)
+print(sensor.read_ambient_temp())
+print(sensor.read_object_temp())
+```
 
-![demo](docs/GY-906-MLX90614.jpg)
+Continuous measurement
+
+```
+import time
+import mlx90614
+from machine import I2C, Pin
+i2c = I2C(scl=Pin(5), sda=Pin(4))
+sensor = mlx90614.MLX90614(i2c)
+
+while True:
+	print(sensor.read_ambient_temp(), sensor.read_object_temp())
+	time.sleep_ms(500)
