ENS160+AHT2X no data to retrieve regarding Air Quality (NOT RELATED TO ESPHOME) about olive-turtle HOT 11 OPEN

Possible sensor replacements:

• SGP30
• CCS811
• SM300D2 $$$$
• SparkFun Environmental Combo Breakout - ENS160/BME280 (Qwiic)

from olive-turtle.

Does it mean you do not suggest buying this sensor?
Have someone tried the Adafruit breakboard with this sensor?

from olive-turtle.

Not what I mean, in fact I am considering replacing this sensor with a sparkfun ENS160+BME combo shield.

It's just that this specific sensor (AHT2X+ENS160) is giving me problems, I tried contacting the seller to understand if I made some mistake but as of now "DFRobot_ENS160" lib most of the times returns 0 on all values and "SparkFun Indoor Air Quality Sensor - ENS160" lib returns "no data to retrieve".

Keep in mind this is an academic project so there is a non zero probability that I'm making a mistake somewhere...

Will update issue to be more specific, sorry for the misunderstanding

from olive-turtle.

When you are talking about "returns 0 on all values", which values do you want to get?
Does your bug block the merge into esphome?

from olive-turtle.

Referring to all data provided by ENS160 (AQI, TVOC, eCO2, status).

It actually has nothing to do with esphome, I referenced the PR here as a way to keep track of my steps (since I was trying the implementation used there) but I forgot that GitHub keeps track of everywhere a PR has been mentioned...

As soon as I realized that my mention was appearing in the PR I removed the mention from here (but unfortunately it is still there)

from olive-turtle.

This is in no way a problem related to the ESPHome implementation of ENS160, which, by the way, works perfectly (in my case returns the same error as the SparkFun lib but in less time)

Have you tried the software on the official home page of the sensor: https://downloads.sciosense.com/ens160/

from olive-turtle.

I'm looking into it but as far as I understand I would need an I2C to USB converter and I have none

from olive-turtle.

unless i make one using esp32

from olive-turtle.

If you use the sensor in ENS160_OPMODE_CUSTOM mode then only raw resistance values will be reported as I read somewhere. Do you use it in ENS160_OPMODE_STD mode?

from olive-turtle.

Sorry for the late reply...
Can't find that mode in SparkFun_ENS160 lib.
Only modes I have are

#define SFE_ENS160_DEEP_SLEEP 0x00
#define SFE_ENS160_IDLE 0x01
#define SFE_ENS160_STANDARD 0x02
#define SFE_ENS160_RESET 0xF0```
