Light Sensor

Light Sensor is an analog sensor capable of reading the level of light falling on it.

---

LightSensor(slot) -> ADC

To create LightSensor object call LightSensor(slot).

Also you can use short alias Light(slot).

Since the light sensor is analog, it can only be inserted into slots with an ADC (analog-to-digital converter), and there are only 2 such slots on the PiBody: "C" and "F".

Args:

• slot (string) - slot label ("C", "F").

Returns: Return an ADC object for the analogue pin of slot.

from pibody import LightSensor

light = LightSensor("C")

---

.read() -> float

Returns value in range [0, 1.0].

light.read()

from pibody import Light  # short alias

light = Light("C")

while True:
    print("light value:", light.read())

---

.read_u16() -> int

Read the raw ADC value in range [0, 65535].

data = light.read_u16()
print(data)

---

.read_uv() -> int

Read the ADC value converted to microvolts.

data = light.read_uv()
print(data)

---

.deinit()

Disable the ADC and release the pin for alternative use.

light.deinit()
