Thanks for suggesting this! I assume the 2.0
, 5.4
etc are your offset values in the above code?
Yes, -2.0, +5.4 and +11.0 [note: signs are needed] are the offset values I found helpful, but would be better placed in config.py
There was previous discussion that ability to calibrate readings would be useful, as the raw readings can be some way off.
Presently, I';ve tweaked enviro/boards/grow.py as below, but it would surely be better done in config.py (and similar likely applies to ther boards?)
def get_sensor_readings():
bme280 returns the register contents immediately and then starts a new reading
we want the current reading so do a dummy read to discard register contents first
bme280.read() time.sleep(0.1) bme280_data = bme280.read() adj_temp = bme280_data[0] - 2.0 adj_press = (bme280_data[1] / 100.0) + 5.4 adj_humidity = bme280_data[2] + 11.0
ltr_data = ltr559.get_reading()
moisture_levels = moisture_readings()
water(moisture_levels) # run pumps if needed
from ucollections import OrderedDict
return OrderedDict({ "temperature": round(adj_temp, 2), "humidity": round(adj_humidity, 2), "pressure": round(adj_press, 2), "luminance": round(ltr_data[BreakoutLTR559.LUX], 2),
