Good sensitivity for garage use

Works well for monitoring CO levels in my workshop when cars are running. It picks up changes quickly. Just make sure you provide adequate ventilation during testing.

Perfect for DIY Safety Projects

I integrated this module into a custom home automation system. The analog output is stable and easy to read with an Arduino. Calibration was straightforward following the datasheet.

Great value for the price

The build quality is solid for the cost. The digital threshold adjustment potentiometer is a nice touch. Took about 24 hours of warm-up time to stabilize completely.

Decent but needs calibration

The sensor works as described, but it required significant calibration out of the box to match our reference equipment. Once tuned, it performs adequately for general monitoring.

Reliable component

Bought this to replace a faulty sensor in an older alarm unit. It fits perfectly and the readings match our standalone detector. Very satisfied with the purchase.

5 FAQ

Q: Is this suitable for detecting natural gas or methane?

A: No, this specific model (ZE16-CO) is designed exclusively for Carbon Monoxide detection. Please look for our methane-specific sensors for natural gas applications.

Q: What is the expected lifespan of the sensing element?

A: Under normal operating conditions, the ZE16-CO sensing element typically lasts approximately 2 years. Exposure to extreme temperatures or silicone vapors may reduce this lifespan.

Q: Does this module come pre-calibrated for immediate use?

A: The module undergoes factory testing, but we recommend a 24-hour warm-up period and fine-tuning the threshold potentiometer for your specific environment before final installation.

Q: Can this be used directly with a Raspberry Pi?

A: Yes, since it provides a 3.3V/5V compatible TTL digital output and an analog signal, it can be easily interfaced with a Raspberry Pi using an ADC hat or GPIO pins.

Q: Does the package include mounting hardware?

A: The package includes the sensor module and a connector cable. Mounting screws or brackets are not included, but the module has standard mounting holes for M2 screws.
