4 years ago The box is not the reason. As turned out, bme280 sensor is not so good for measuring temperature. On the first place for this sensor are pressure and humidity. Temperature is available just for environment condition assessment. There are two ways for resolving this situation:
- Use another sensor for measuring temperature only.
- Collibrate bme280 if it's possible. Anyway another sensor is necessary.
The new plan is:
- attach another sensor to wemos;
- compare values;
- if callibration is possible - collibrate it and continue to use bme280. If not - use another sensor.
The reason is box probably. ESP8266 chip is pretty warm and can make a mistake for temperature. Plan:
