This module provides access to the AM2320 humidity and temperature sensor, using the i2c interface.
This code is licensed under GPL by its author. Any binaries that include this module becomes subject to the GPL, requiring anyone who ships them to also ship source.
Samples the sensor and returns the relative humidity in % and temperature in celsius, as an integer multiplied with 10.
relative humiditypercentage multiplied with 10 (integer)
temperaturein celcius multiplied with 10 (integer)
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))
Initializes the module. Returns model, version, serial but is seams these where all zero on my model.
model, version, serial = am2320.setup()
model16 bits number of model
version8 bits version number
serial32 bits serial number
Note: I have only observed values of 0 for all of these, maybe other sensors return more sensible readings.
