Why is hydrogen such a big issue for CO sensors? | GfG ...

However, the hydrogen leak mostly affected the CO readings, and not the readings from the LEL sensors in the instruments we are currently using. We would pick up 0-5% LEL from time to time, but pretty constantly stay at about 50-250 ppm CO even though we knew that could not be right since CO can only be present as a byproduct of combustion from ...

How Water Sensors Can Help Prevent Costly Water Damage ...

Some water-sensor systems can be programmed to shut off the water to the house to help prevent a small leak from becoming a large one. If your home is heated by an older steam-heating system, or if it’s protected by an automatic fire sprinkler system, check with a qualified professional before installing sensor-activated water shut-off devices.

Water Leak Sensor - Aqara

The Aqara Water Leak Sensor makes use of the electrical conductivity of water. When two probes come into contact with water, a current loop is formed. At the same time, the sensor reports water leak/water immersion status to the Aqara Hub and thereby triggers the alarm or interacts with other smart devices to perform related operations.

May 22, 2019· Reference voltage at non-inverting pin 3 of IC2 is set using potmeter VR1 to adjust voltage levels based on sensitivity requirements. LPG sensor (MQ-6) output voltage is fed to inverting pin 2 of IC2. If reference voltage (pin 3 of IC2) is less than sensor voltage (pin 2 of IC2), output goes low, which means there is no LPG leakage.
