This module provides access to the AM2320 humidity and temperature sensor, using the i2c interface.
am2320.read()¶
Samples the sensor and returns the relative humidity in % and temperature in celsius, as an integer multiplied with 10.
Syntax¶
am2320.read()
Returns¶
relative humidity
percentage multiplied with 10 (integer)temperature
in celcius multiplied with 10 (integer)
Example¶
sda, scl = 1, 2
i2c.setup(0, sda, scl, i2c.SLOW) -- call i2c.setup() only once
am2320.setup()
rh, t = am2320.read()
print(string.format("RH: %s%%", rh / 10))
print(string.format("Temperature: %s degrees C", t / 10))
am2320.setup()¶
Initializes the module. Returns model, version, serial but is seams these where all zero on my model.
Syntax¶
model, version, serial = am2320.setup()
Parameters¶
None
Returns¶
model
16 bits number of modelversion
8 bits version numberserial
32 bits serial number
Note: I have only observed values of 0 for all of these, maybe other sensors return more sensible readings.
