Re: MQ2 gas sensor
At least, test.py does not work as is, it must have import MQ as module: import MQ from MQ import MQ2 import utime class App: def __init__(self, pin = 0): self.sensor = MQ2.MQ2(pinData = pin, baseVoltage = 3.3) def Run(self): print("Calibrating") self.sensor.calibrate() print("Calibration completed"...

MQ2 gas sensor
Hi,
I have MQ2 gas sensor with digital and analog pins (4 pins, D0, A0, Gnd, Vcc).
Is there anyone do thw program to read this senso with pure micropython on ESP8266 Lolin board?
Thanx in advance,
Jadro

Re: LILYGO TTGO T-Call ESP32
Hi, sorry on my late answer,
I think is not problem in battery current because I put txt logging and it not reconnects, just dont send messages or calls. If current is problem then it would restart i think.

Re: LILYGO TTGO T-Call ESP32
I think problem is in UART connection, I'am not familiar with it... In code, there is initialization uart = UART(1, 9600, timeout=1000, rx=self.MODEM_TX_PIN, tx=self.MODEM_RX_PIN) where MODEM_TX_PIN = 26 and MODEM_RX_PIN = 27 and when on USB this is OK but what if battery is connected and USB power ...
