BME280 sensor with MIND+ and python
Pedro.Hepp 2024-04-25 12:05:57 628 Views5 Replies Hi, what is the Mind+ python code to access sensor data from a BME280 sensor?
Please provide a small functional code.
Thank you very much
I seem to be able to read the sensor for temperature and pressure<a href="https://minimilitiamodapk.com/">.</a>
john.smith5305 I seem to be able to read the sensor for temperature and pressure.
john.smith5305 “TypeError: 'NoneType' object is not subscriptable” means you don't find the sensor. You need to verify that the sensor is correctly connected and Pins are properly defined.
Lupin Below is the Python sample code which could run on UNIHIKER, if that what you are looking for.
from pinpong.libs.dfrobot_bme280 import BME280
from pinpong.board import Board
import time
Board().begin()
p_bme280 = BME280()
while True:
print(p_bme280.temp_c())
print(p_bme280.humidity())
print(p_bme280.cal_altitudu())
print(p_bme280.press_pa())
time.sleep(1)

I tried that code before on a UNIHIKER Board and got this error message:
Traceback (most recent call last):
File "/root/mindplus/cache/new-project-25-4-2024-8-22-4.mp/BME280.py", line 6, in <module>
p_bme280 = BME280()
File "/usr/local/lib/python3.7/dist-packages/pinpong/libs/dfrobot_bme280.py", line 54, in __init__
while not self.begin():

TypeError: 'NoneType' object is not subscriptable
root@unihiker:~/mindplus/cache/new-project-25-4-2024-8-22-4.mp#
This is line 6 causing the error:
p_bme280 = BME280()
Is it a problem with the UNIHIKER board perhaps?
