I hate to disappoint you @micah but @Mike-Musskopf has got a point: MQ* sensors are power hungry. You may want to connect everything up to 240V via a small PSU. There is a big thread on mysensors about air quality detection. DHT is not the best sensor for a battery application. Please check BME280 (pressure, temp and hum) or Si7021 (temp and hum) - these would be my favourite sensors for low power consumption. Small tip - your Arduino Pros must be 3.3V and not 5V for the battery usage.

@bisschopsr said in BlackCircle Sensor - High "WAF" Temp/Hum. sensor: Hi All, Like the design thinking of this, although an older topic I did manage to get me one of these dishes. After taking it apart, I have one question that came to mind. Is the ventilation in the dish enough for the humity sensor? Is there any experience with that after running this sensor for a while? Thx Ralph Hello, yes I think it's enough, in fact there's much more ventilation than in many commercial sensors which only have a small hole. But it's a good test to make, I'll try to compare to a sensor out of it's enclosure to see if there's significant difference or delay.

@Samuel235 I am looking at a CO sensor too, do you have any updates on the ones you are using? What is the exact model?
